MyMycoLab Review: Mycotoxin Blood Serum Antibody Test

What is MyMycoLab

MyMycoLab is a laboratory that specializes in one thing: measuring antibodies to mycotoxins in blood serum. Mycotoxins are toxic compounds that some molds produce. Rather than trying to detect those compounds directly, MyMycoLab looks for the antibodies your immune system makes in response to them. The company describes this as an indirect test, similar in concept to testing for antibodies to an infection instead of hunting for the pathogen itself.

That framing is the whole story with MyMycoLab, so it is worth slowing down on. Most mold body tests on the market are urine mycotoxin panels, which try to measure the toxins your body is clearing. MyMycoLab does something different. It measures IgG and IgE antibodies against 14 mycotoxins, which produces 28 results in total, and it positions this immune-response signal as its point of difference. The lab markets itself as the specialist in serum mycotoxin antibody testing.

The important thing to understand up front is what category this product sits in. This is a body test, not an environmental one. It samples your blood, not your home, so it cannot tell you whether mold is growing in your house or where. It is also not a diagnosis. We come back to that distinction throughout this review, because it is the single most common point of confusion for buyers.

How the test works

The flow is straightforward, with one step that sets it apart from urine kits: you need a blood draw.

• Create an account and order. MyMycoLab states you can create a patient account and order the test yourself through its portal, with no physician referral required. The kit ships to you.
• Get your blood drawn. A phlebotomist collects the sample. MyMycoLab says you can use several venues, such as your own doctor's office, an AnyLabTestNow location (the company cites a large national network), or a mobile phlebotomy service that comes to you. The kit includes instructions for the phlebotomist.
• Ship the serum back. The serum sample is packaged and shipped to the lab per the kit directions.
• The lab measures antibodies. Instead of measuring mycotoxins directly, the lab measures IgG and IgE antibodies to 14 mycotoxins. IgG and IgE are two classes of antibody your immune system can produce, and the test reports a result for each toxin in both classes.
• You get a report plus interpretation. MyMycoLab states results take about 14 business days from the day the lab receives your serum, and each result comes with a written clinical interpretation. The lab's medical advisor also offers a complimentary consultation to walk through the numbers.

That blood-draw requirement is the practical trade-off versus a urine kit. It adds a step and, depending on where you go, a phlebotomy fee, but it is also what enables the antibody approach. Whether that approach is the right one is the debate we cover in the science section.

What it tests for and what you get

The headline is 14 mycotoxins measured in two antibody classes, IgG and IgE, for a 28 marker panel. MyMycoLab reports that its panel was expanded over time and now includes toxins such as Fumonisin B1 and Zearalenone alongside the mycotoxin families commonly associated with indoor mold. The lab publishes the full itemized list on its own site, and because panel contents can change, that is the place to confirm exactly which 14 are current before you buy.

What IgG and IgE are meant to signal

MyMycoLab offers its own interpretation of the two classes. It describes IgG as a marker it associates with current exposure or colonization, one it says tends to fall once the exposure is addressed. It describes IgE as a marker it associates with current exposure and with allergy or mast cell reactivity. These interpretations come from MyMycoLab, and they are not standardized reference ranges recognized across mainstream laboratory medicine, so any result should be read by a clinician who understands the context. If you want the wider picture of body-level testing, read our guide to mycotoxin testing.

Pricing and what is included

MyMycoLab lists the panel of 28 antibodies, IgG and IgE for 14 mycotoxins, at $380. That covers the kit and the lab analysis, and it comes with the written interpretation and the option of a consultation. Because lab pricing shifts, confirm the current figure on the official site rather than trusting any third-party number, including this page.

A few money details worth knowing:

• The blood draw may cost extra. The $380 covers the lab work. If your phlebotomy venue charges a draw fee, that is separate and paid where you get drawn.
• No physician referral required. You can order directly, which removes a gatekeeping step some other clinical tests still have.
• No insurance billing. MyMycoLab states it does not bill insurance, so plan on paying out of pocket.
• Shipping caveats. International return shipping is not included in the listed price, so overseas buyers should budget for it.

Put the cost in context. A single professional mold inspection of a home often runs several hundred dollars and sometimes more, and it tells you about the building. A blood antibody panel at $380 tells you about your body's immune response. They are not substitutes, which is why some people end up paying for both. Decide what question you actually need answered before you spend.

Accuracy, science, and credentials

This is the section that separates a fair review from a sales pitch, because the antibody approach is exactly where the debate lives.

What is genuinely in its favor

MyMycoLab states that its laboratory is certified and validated, with more than two decades of work behind the method, and that every result ships with a written clinical interpretation running to many references. It also has a real, named physician behind it. Dr. Andrew Campbell, MD is the lab's medical advisor, a physician known for work on mold and environmental illness who has served as an editor for the journal Alternative Therapies in Health and Medicine, and he offers a complimentary consultation to review results. Having a credentialed physician attached, plus a written interpretation, is more than many wellness tests can say.

The method is contested, and that is the honest catch

Here is the part the marketing tends to skip. Serum mycotoxin antibody testing is a niche, single-lab methodology. Mainstream medical bodies, including the CDC and FDA, do not recognize mycotoxin testing as a validated way to diagnose mold related illness, and there are no agreed cross-lab reference ranges that tell you which antibody level is normal and which one signals a problem. MyMycoLab argues its approach is more accurate than urine mycotoxin testing, and independent practitioners have noted there is little correlation between antibody results and urine results, which is another way of saying the field has not settled on a single trusted signal. When one methodology is the primary place a test is offered, there is limited independent, third-party validation to lean on.

None of this means MyMycoLab runs a bad lab or that Dr. Campbell is not credible. It means the test measures a real biological signal whose clinical meaning is genuinely unsettled, and the honest way to use it is as one input for a knowledgeable clinician, not a verdict. A result on its own does not prove where any exposure came from, whether it is causing a health issue, or what to do about it.

Blood versus urine

You will see labs on both sides of this argument. Urine mycotoxin panels (from labs like RealTime and Mosaic) try to measure the toxins your body is clearing. MyMycoLab measures antibodies to those toxins instead. Each camp argues its signal is more meaningful, and there is no independent standard that crowns a winner. Both share the same underlying limitation on clinical interpretation, and both measure your body rather than your home.

Pros

• A genuinely different approach. Measuring IgG and IgE antibodies is a distinct method from the urine panels that dominate the category, which may appeal to people who distrust urine provocation testing.
• Comprehensive panel. Fourteen mycotoxins across two antibody classes is a broad 28 marker readout rather than a narrow single-toxin check.
• A named physician behind it. Dr. Andrew Campbell, MD, an established figure in mold and environmental illness, is the medical advisor and offers a consultation on results.
• Interpretation included. Every result comes with a written clinical interpretation, which most direct-to-consumer tests do not provide.
• Order it yourself. No physician referral is required to buy, so there is no doctor gatekeeping step to get started.
• Flexible draw options. You can get blood drawn at your own doctor's office, a national walk-in lab network, or through mobile phlebotomy.

Cons and limitations

• It measures your body, not your building. This is the big one. A blood panel cannot tell you whether mold is growing in your home or where. It is the wrong tool if your goal is to find a source.
• The science is contested. Serum mycotoxin antibody testing is not recognized by the CDC or FDA as a validated diagnostic, and there are no agreed cross-lab reference ranges.
• Single-lab methodology. Because this approach is offered primarily by one lab, there is limited independent, third-party validation and little correlation with other mold body tests.
• It requires a blood draw. Unlike an at-home urine kit, you need a phlebotomy appointment, which adds a step and a possible separate fee.
• Interpretation is not standardized. The IgG and IgE meanings come from the lab itself, so results really need a knowledgeable clinician to put in context.
• Cost adds up. At $380, plus any draw fee, plus possible practitioner visits or a separate environmental test, the total spend can climb quickly, and insurance is not billed.
• No treatment guidance from us. A test result is data. What to do about it, if anything, is a medical conversation for a licensed clinician, not a website.

Who it is best for (and who should skip it)

Best for

People working with a functional medicine or environmental health provider who is specifically interested in an antibody-based signal and knows how to weigh it. If you have a clinician who wants to look at your immune response to mycotoxins as one piece of a larger picture, and who understands the method's limits, the panel gives them a data point plus a written interpretation to discuss. It also suits people who distrust urine provocation testing and prefer a blood-based approach, provided they go in with clear expectations about what the result can and cannot say.

Who should skip it

Anyone whose actual question is is there mold in my house. A blood test will not answer that, and buying one first is a common and expensive detour. If you are trying to locate a source, prove a leak caused growth, or decide whether to remediate, your money goes further on testing the building first. People who want a validated, universally accepted diagnosis should also be cautious, because the method is contested and the results genuinely need a clinician's context.

How it compares to alternatives

Versus urine mycotoxin labs (RealTime, Mosaic)

This is the closest comparison. Urine labs such as RealTime Laboratories and Mosaic Diagnostics measure the mycotoxins your body is clearing, often reporting parts-per-billion values. MyMycoLab instead measures antibodies to those toxins. MyMycoLab argues the antibody approach is more accurate, while urine labs argue direct measurement is more meaningful. There is no independent standard that settles it, and practitioners note the two methods do not correlate well. All of them measure your body, and all share the same limitation on clinical interpretation.

Versus DIY mold test kits

A hardware-store mold plate or a DIY mold testing kit samples air or a surface in your home to see what grows. That tells you something about the building, not your body, and cheap settling-plate kits are notoriously unreliable. MyMycoLab and a DIY kit are not competitors. They answer opposite questions, and the DIY kit answers the more useful one for most homeowners, however imperfectly.

Versus environmental dust testing (ERMI)

An ERMI test analyzes household dust for mold DNA to estimate the mold burden inside a home. If you want to understand the building, an environmental dust test is the right family of tool, not a blood antibody panel. The two answer completely different questions.

Versus a professional inspection

A qualified inspector who follows the IICRC S520 standard (or holds ACAC or RIA credentials or a state license) physically examines the home, checks moisture, and can sample air and surfaces. That is the gold standard for finding and scoping a real mold problem in a building. It costs more than a test kit and answers the where and how bad questions that no blood panel can. If you are making a high-stakes property or lease decision, this is the path.

The short version: MyMycoLab competes with other body tests, mainly urine mycotoxin labs. It does not compete with anything that tells you about your house. For that, see our full guide on how to test for mold.

How to use it step by step

• Step 1: Decide what you actually want to know. If the question is about your home, test the home first. If the question is about your body and you have a provider to interpret it, continue.
• Step 2: Order the kit. Create a patient account on MyMycoLab and order the panel. No physician referral is required to buy.
• Step 3: Book a blood draw. Arrange phlebotomy at your doctor's office, a walk-in lab location, or a mobile service. Confirm any draw fee up front.
• Step 4: Have the sample collected. Bring the kit so the phlebotomist can follow the included instructions, then package the serum as directed.
• Step 5: Ship it back promptly. Send the serum to the lab following the kit directions so it stays stable in transit.
• Step 6: Review results with a professional. When your report and written interpretation arrive in about 14 business days, go over the IgG and IgE values with a qualified clinician, and use the complimentary advisor consultation if you want it. Do not self-diagnose from the numbers.
• Step 7: If the concern is your home, act on the building. Whatever the report says, a mold problem is fixed at the source. Find the moisture, find the growth, address it, and keep humidity in check.

Our verdict and rating

Our rating: 4.5 / 5. MyMycoLab is a credible, distinctive product on the parts it controls. The blood serum antibody approach is genuinely different, the 14 mycotoxin, 28 marker panel is comprehensive, it comes with a written interpretation, and it is backed by a named physician advisor in Dr. Andrew Campbell, MD. For someone working with a provider who specifically wants an antibody-based signal, it is a legitimate option and a change of pace from the urine panels that dominate the category.

The one thing to go in clear-eyed about is the method, not the lab's professionalism. Serum mycotoxin antibody testing is contested, it is a single-lab approach with limited independent validation, mainstream agencies do not recognize mycotoxin testing as a validated diagnosis, and there are no standard cross-lab reference ranges. It also requires a blood draw and, at $380 with no insurance billing, it is not cheap. Most importantly for our readers, the test looks at your body and cannot tell you whether or where mold is growing in your home.

Bottom line: if a clinician is guiding you, you want an antibody approach, and you understand what the result can and cannot say, MyMycoLab is a reasonable pick. If you are trying to figure out whether your house has a mold problem, this is the wrong first purchase. Find the mold in the building first.

Find the mold before you test

A blood antibody panel measures how your immune system may be responding. It cannot point at the corner of the ceiling, the caulk behind the shower, or the spot under the sink where the problem actually lives. That is the gap Mold Scanner AI fills. Before you spend on any body test, use the app to locate the exact hotspots in your home so you know what to sample and where to fix. It walks you through the same rooms and surfaces a professional inspector checks, and it gives you an AI verdict from a single photo in about 30 seconds. Start with the building, confirm the source, then decide whether any body-level testing is worth it with your clinician. See how Mold Scanner AI works.
