What Your Labs Aren’t Telling You

How supplements and medications can quietly change your test results.

You fast the night before. You show up on time. You roll up your sleeve and do everything right. So when a lab result comes back abnormal, it’s natural to assume it means something is wrong.

But sometimes, the result isn’t wrong because of your health. It’s wrong because of something you took that morning, or even days earlier — a vitamin, a supplement, an over-the-counter pill — that quietly changed the number on the page.

This happens more often than most people realize. And it can go both ways: it can make a healthy result look alarming, or it can make a real problem look normal. Either way, it can send you and your doctor down the wrong path.

Here’s what you need to know before your next test.

The supplement almost no one thinks about: biotin

Biotin, also called vitamin B7, is one of the most common ingredients in hair, skin, and nail supplements — and it is also one of the most well-documented causes of inaccurate lab results.

The FDA has issued more than one public warning about this. Biotin can interfere with a type of lab test called an immunoassay, which is used to measure many common markers, including thyroid hormones and troponin, the marker used to help diagnose a heart attack.

The FDA has received reports of biotin causing falsely low troponin results — including at least one report where this may have contributed to a missed diagnosis. Biotin has also been linked to inaccurate results for thyroid tests, vitamin D, vitamin B12, ferritin, testosterone, and several other common markers.

The supplements involved aren’t exotic. Many hair, skin, and nail products contain biotin doses far above what your body actually needs — sometimes hundreds of times higher. If you take one of these, or a multivitamin that includes biotin, your lab results could be affected without you ever knowing why.

What to do

Tell your provider and the lab if you take biotin in any form, including multivitamins and hair, skin, or nail supplements. Many providers recommend stopping biotin for two to three days before bloodwork, though you should always confirm this with your provider rather than stopping supplements on your own.

Other common supplements worth mentioning

Biotin gets the most attention, but it isn’t the only one. Here are other supplements known to affect common tests:

  • Vitamin C (high dose). Can throw off some glucose readings and certain stool tests used to screen for colorectal cancer or digestive bleeding.
  • Calcium supplements. Taking calcium before a bone density scan can make your bones appear denser than they really are.
  • Creatine. Commonly used for muscle and exercise support, creatine can raise a marker called creatinine, which is used to check kidney function — potentially making healthy kidneys look impaired.
  • Iron supplements. Can cause a false-positive result on a stool test used to check for hidden digestive bleeding.
  • Fish oil and niacin. Both can genuinely change cholesterol and triglyceride numbers, which is useful to know if you’re trying to track your true baseline.

This is not a complete list, and new research comes out regularly. The point isn’t to memorize every interaction — it’s to understand that supplements, even ones that seem harmless, can influence what your test results show.

It’s not just supplements

Prescription and over-the-counter medications can affect lab results too. A few well-documented examples: certain antibiotics can cause false readings on kidney and urine tests. Acid-reducing medications, a category that includes common heartburn drugs, have been linked to changes in certain hormone and breath-test results, and may affect blood-thinner monitoring in some patients. Even some blood thinners themselves can affect clotting-related lab values in ways your provider needs to account for.

The theme is the same as with supplements: what you take can change what the test shows, and your provider can only account for it if they know about it.

What this means for you

None of this means you should stop taking your supplements or medications on your own, or that you should distrust every lab result you’ve ever received. Most of the time, your results reflect exactly what’s happening in your body.

What it does mean is this: a full and honest list of everything you take is one of the most valuable pieces of information you can hand your provider — every single time you’re tested.

Before your next blood draw, test, or scan, consider bringing a simple list that includes:

  • Every prescription medication you take
  • Every over-the-counter medication, even ones you only take occasionally
  • Every vitamin and supplement, including multivitamins
  • Any recent change — something new you started, or something you recently stopped

If a result ever comes back and doesn’t match how you feel, or doesn’t make sense given your history, it’s fair to ask your provider directly: “Could anything I’m taking have affected this result?” That single question has, in documented cases, changed a diagnosis.

You know your whole story. Make sure your provider does too.

Reading your medical records and asking good questions only works if the information going in is complete. A lab result is only as accurate as the full picture behind it — and you’re the only one who knows everything you’re taking.

Keep a current list. Bring it every time. It’s a small habit that can prevent a very large misunderstanding.

How to Request Your Medical Records — and What to Do Once You Have Them

In my previous post, I walked through five things every patient should check in their own medical records. But that advice is only useful if you actually have your records in hand — and most people don’t.

It’s not because they can’t get them. It’s because nobody ever told them they could.

You have a legal right to your complete medical record. Federal law — specifically HIPAA, the Health Insurance Portability and Accountability Act — requires every healthcare provider to give you access to your medical records upon request. This includes hospitals, physician offices, laboratories, imaging centers, and any other entity that creates or maintains records about your care. They cannot refuse, and they cannot require you to explain why you want them.

This post is the practical companion to that right. I’m going to walk you through exactly how to request your records, what to expect when they arrive, and how to organize them into something you can actually use.

Step 1: Know what you’re entitled to

Under HIPAA, you have the right to obtain copies of virtually everything in your medical file. This includes physician notes and visit summaries, laboratory results, pathology reports, imaging reports (radiology, ultrasound, MRI, CT, PET scans), surgical and procedure notes, hospital admission and discharge summaries, medication lists, immunization records, and billing records.

You are also entitled to request the actual images from imaging studies — not just the written report, but the scans themselves, typically provided on a CD or through a digital portal. This matters if you’re seeking a second opinion, because the reviewing physician needs to see the images, not just read another doctor’s interpretation of them.

There are very narrow exceptions to what providers must release — psychotherapy notes kept separately from your medical record and information compiled for legal proceedings, for example — but for the vast majority of patients, your entire chart is yours to request and review.

Step 2: Submit a written request

You can request records verbally in some cases, but a written request creates a paper trail and is harder to ignore or lose. Here’s how to do it properly.

Contact the medical records department — not the front desk, not your doctor’s office staff, but the Health Information Management (HIM) or Medical Records department specifically. Every hospital and large practice has one. For smaller practices, the office manager usually handles records requests.

Your written request should include your full legal name (and any prior names the records might be filed under), your date of birth, your address and phone number, the specific records you’re requesting (be as detailed as possible — don’t just say “my records,” say “all records including lab results, pathology reports, imaging reports, and physician notes from January 2023 through present”), the format you want them in (electronic copies are usually faster and easier to work with than paper), and your signature and the date.

Most facilities have their own authorization form they’ll ask you to complete. That’s fine — fill out theirs, but keep a copy of your own written request as well. Having both creates a stronger record that the request was made and what specifically was asked for.

Step 3: Know the rules around timing and fees

Under HIPAA, providers must respond to your request within 30 days. They can request a single 30-day extension if they notify you in writing, but beyond that, they are in violation. If you’re being stalled or ignored, you have the right to file a complaint with the U.S. Department of Health and Human Services Office for Civil Rights.

Regarding fees, providers can charge a reasonable cost-based fee for copies, but many states have specific limits on what they can charge per page. Electronic copies are generally less expensive than paper. Some patient portals allow you to download records at no cost. If you’re being quoted a fee that seems excessive, check your state’s medical records fee schedule — your state’s Department of Health website usually has this information.

One important note: a provider cannot withhold your records because you have an unpaid balance. Your right to access your records is not contingent on your account status.

Step 4: Request from every source — not just your primary doctor

This is where most people stop too soon. They request records from their primary care physician or the hospital where they were recently treated, and they think they have everything. They almost certainly don’t.

Your medical history is scattered across every provider who has ever touched your care. That includes your primary care physician’s office, every specialist you’ve seen (oncologist, cardiologist, orthopedist — all of them), every hospital where you’ve been admitted or treated, every laboratory that has processed your blood work or specimens, every imaging center where you’ve had scans performed, urgent care or emergency room visits, and any previous providers you saw years ago who may still have records on file.

Each of these facilities maintains their own records. They don’t automatically share complete files with each other. The pathology report from a biopsy performed at one hospital may never have been seen by the physician at another facility who is now making treatment decisions based on an incomplete picture.

Request records from every source. Cast a wide net. You may be surprised by what turns up in records you didn’t know existed — and what’s missing from records you assumed were complete.

Step 5: Organize what you receive

This is where most people get overwhelmed. A stack of medical records — or a folder of PDFs — can be hundreds of pages long, filled with abbreviations, medical terminology, and formatting that varies wildly from one facility to the next. The temptation is to flip through it, get confused, and put it away.

Don’t do that. Instead, organize it.

Start by sorting everything chronologically — oldest to newest. Use the dates of service, not the dates the records were printed or sent to you. This gives you a timeline of your care from beginning to present.

Next, separate records by type. Group all lab results together, all imaging reports together, all physician notes together, all pathology reports together. Within each group, maintain the chronological order.

Create a simple master timeline — a spreadsheet or even a handwritten list — that captures every significant event: each office visit, each test, each procedure, each diagnosis, each change in treatment. Include the date, the provider, the facility, and a one-line summary of what happened. When you’re done, you’ll have something most patients and even many physicians don’t: a clear, chronological picture of your entire medical history in one place.

This timeline is one of the most powerful tools you can bring to any medical appointment, second opinion consultation, or insurance appeal. It shows that you know your own history, you’ve done the work, and you’re paying attention.

Step 6: Read everything — and take notes

Once organized, read through your records. All of them. Not just the summaries and conclusions — the full reports, the detailed findings, the notes your physicians wrote after each visit.

As you read, keep a notebook or a digital document open and write down anything that catches your attention. Things like a result that seems inconsistent with how you were feeling at the time, a date that doesn’t match your memory of when something happened, a provider’s name you don’t recognize, a diagnosis listed that was never discussed with you, a test result from one lab that looks dramatically different from the same test at a different lab, or a reference to a prior study or report that you don’t have in your collection.

You are not looking for problems. You are looking for anything that doesn’t line up. Most of the time, there will be a perfectly reasonable explanation. But you won’t get that explanation unless you notice the discrepancy and ask about it. And you won’t notice it unless you read the records.

Step 7: Bring your questions to your provider

This is not about confrontation. This is about collaboration.

When you find something in your records that you don’t understand or that doesn’t seem right, write it down clearly — the specific document, the specific page, the specific detail — and bring it to your next appointment. Frame it as a question, not an accusation. “I was reviewing my records and noticed that this report lists a different date than what I recall — can you help me understand that?” or “I see two lab results for the same test from different facilities and the numbers are quite different — are those comparable?”

Most physicians will respect this. Many will be impressed by it. Some may be uncomfortable, and that discomfort can itself be informative — but your job is to ask the question clearly and listen carefully to the answer.

You are not overstepping by reading your own records and asking questions about them. You are doing exactly what an informed, responsible patient should do. The healthcare system works better when patients participate in their own care — and participation starts with information.

One more thing

If you take nothing else from this post, take this: request your records before you need them.

Don’t wait until you’re in a crisis, facing a difficult diagnosis, or preparing for a difficult conversation to start gathering your medical history. Do it now, while things are calm and you have the bandwidth to read carefully and organize thoroughly. Build your file. Maintain it. Update it after every significant visit or test.

The patients who navigate the healthcare system most effectively are the ones who know their own records inside and out. They walk into every appointment with context. They ask better questions because they’ve done the reading. That kind of preparation isn’t paranoia — it’s self-advocacy.

There’s more to that story, though. Getting records early doesn’t just make appointments smoother — there are real, time-sensitive reasons the calendar itself can work against you, and reasons a finding can sit unseen in a report for years. That’s exactly why I wrote The Paper Trail: to explain why timing matters and what waiting can cost you.

Five Things Every One Should Check in Their Own Medical Records

Your medical records tell the story of your health. But what happens when that story contains errors? Here are five things every patient should verify — before someone else makes a decision based on them.

Your medical records are the foundation of every medical decision made about you. Every diagnosis, every prescription, every referral, every second opinion — all of it starts with what’s written in your chart.

Most people never read their own records. They trust that what’s in there is accurate because a medical professional wrote it. That trust is understandable. It’s also, more often than you’d think, misplaced.

Medical records contain errors. Studies have documented error rates ranging from relatively minor misspellings to significant clinical mistakes — wrong test results attributed to the wrong patient, incorrect demographic information, diagnoses carried forward from one visit to the next without anyone verifying the original finding. These aren’t rare edge cases. They happen routinely, across every type of healthcare facility, and most of them are never caught — because the patient never looks.

You have the legal right to obtain and review your own medical records. Under HIPAA, healthcare providers must give you access to your records upon request, typically within 30 days. And once you have them, there are five specific things you should check before anyone makes another decision based on what’s in there.

10 Questions to Ask Yourself Before You Accept Any Diagnosis

Before you accept any diagnosis, there are ten questions worth sitting with. They’re the ones I wish someone had handed me. Free — straight to your inbox.

Send me the free guide

1. Your demographic information — on every single page

This sounds basic, and it is. That’s what makes it so dangerous when it’s wrong.

Check your full name, date of birth, sex, and medical record number (MRN) on every page of every report. Not just the cover sheet — every page. Some multi-page reports carry demographic headers on each page, and those headers don’t always match. A clerical error on one page of a pathology report might mean the difference between your tissue sample and someone else’s.

If you see any inconsistency — a different MRN on page two than page one, an incorrect sex marker, a misspelled name that could belong to another patient — flag it immediately. Don’t assume it’s cosmetic. In a large hospital system processing thousands of specimens and records daily, a single mismatched identifier can mean your results are mixed with another patient’s. And you would never know unless you looked.

2. Dates and provider names across documents

Pull your records together and lay them out chronologically. Do the dates make sense? Does a follow-up report reference the correct date of the original procedure? Does the ordering physician’s name match who you actually saw?

Date errors can create a misleading clinical timeline. If a biopsy report is dated incorrectly, subsequent providers reviewing your chart may draw conclusions based on a sequence of events that didn’t actually happen that way. They may believe a condition progressed faster or slower than it did. They may miss the significance of a gap — or invent significance where none exists.

Provider name errors matter too. If a report lists a physician you never saw, or if the interpreting radiologist on an imaging study differs from what you were told, that’s worth questioning. It doesn’t necessarily mean something went wrong, but it means something doesn’t line up — and in medicine, things that don’t line up deserve an explanation.

3. Lab values and reference ranges

When you get lab results back, most people look at one thing: is it normal or abnormal? The report usually makes this easy with a flag — “H” for high, “L” for low, or a bold marker next to anything outside the reference range.

But here’s what most patients don’t realize: reference ranges vary between laboratories. A result that’s flagged as abnormal at one lab might fall within normal range at another, because different labs use different equipment, different assays, and different calibration standards. If you’ve had the same test run at two different facilities and the numbers look dramatically different, it may not mean your health changed — it may mean the tests aren’t directly comparable.

This matters enormously if your care team is tracking a value over time. If your physician is comparing a result from Lab A six months ago with a result from Lab B today and concluding that something is getting worse, but those two labs use fundamentally different testing platforms, that conclusion may not be valid.

When you review your lab work, note which laboratory performed each test. If the lab changed between draws, ask your provider whether the results are comparable. This is a question most patients never think to ask — but it can change the entire interpretation of your data.

4. Imaging reports — read beyond the conclusion

Most patients, if they read their imaging reports at all, skip straight to the bottom — the impression or conclusion section. That’s the summary where the radiologist gives their overall interpretation. It’s important. But it’s not the whole story.

The body of the report — the findings section — contains the actual observations: measurements, descriptions of what the radiologist saw, comparisons to prior studies, and characterizations using standardized classification systems. Sometimes the findings section contains details that don’t quite match the confidence of the conclusion. A finding described in cautious language in the body of the report may be stated more definitively in the impression. Or a prior study may be referenced for comparison, but when you go pull that prior study, the details don’t align with how they were characterized.

Read the full report. If technical language is unclear, write down the specific terms and look them up — or bring them to your next appointment and ask your physician to explain what each finding means in plain language. You are entitled to understand every word written about your body.

Also check whether prior imaging is referenced accurately. If a current report says “compared to prior study dated March 2023” — go find that March 2023 study and confirm the comparison makes sense. Errors in comparison references can lead to incorrect assessments of whether something has changed, grown, or resolved.

5. Diagnoses that carry forward without re-verification

This is perhaps the most consequential item on this list, and the one least understood by patients.

In medicine, once a diagnosis is entered into your chart, it tends to stay there. It gets carried forward from visit to visit, from provider to provider, from

5. Diagnoses that carry forward without re-verification

This is perhaps the most consequential item on this list, and the one least understood by patients.

In medicine, once a diagnosis is entered into your chart, it tends to stay there. It gets carried forward from visit to visit, from provider to provider, from facility to facility. Each new physician who opens your chart sees the diagnosis listed and, in many cases, accepts it as established fact. They build their own assessment on top of it. They order tests based on it. They recommend treatment based on it.

But what if the original diagnosis was uncertain? What if it was based on a single test that was never repeated? What if the clinical picture has changed in a way that should prompt a fresh look — but nobody goes back to question the original finding because it’s already “in the chart”?

This happens more than most people realize. A finding from years ago, entered during a specific set of circumstances that may no longer apply, can follow you through your entire medical history — shaping decisions made by providers who never examined the original evidence.

When you review your records, look at your active diagnosis list. For each one, ask yourself: when was this first diagnosed, and based on what evidence? Has anyone revisited it recently? Does it still make sense given how I feel and what my current test results show? If something doesn’t add up, bring it to your provider’s attention. You are not questioning their competence — you are doing exactly what a responsible, informed patient should do.

The bottom line

Your medical records are not sacred, infallible documents. They are created by human beings working in high-volume, high-pressure environments, and they are subject to every kind of error that any complex documentation system produces. The difference is that these errors can directly affect your health, your treatment, and your life.

You don’t need a medical degree to review your own records. You need patience, attention to detail, and the willingness to ask questions when something doesn’t look right. That combination — a careful eye and the courage to speak up — is the foundation of effective self-advocacy.

Request your records. Read them. All of them. And if something doesn’t add up, don’t let anyone tell you it doesn’t matter.

It matters. You matter. And nobody will ever care about the accuracy of your medical records more than you do.
