The Only Blood Serum Mycotoxin Test in the U.S.
Test for 14 mycotoxins with both IgG and IgE antibody detection. Total 28 results that show how your immune system is responding to mycotoxin exposure.
Mycotoxins are invisible toxic compounds produced by certain molds. Exposure can happen through water-damaged buildings, contaminated food, workplace environments, and everyday items — often without any visible signs of mold. Because mycotoxin symptoms like fatigue, brain fog, headaches, and gut issues overlap with conditions like Chronic Fatigue Syndrome, Fibromyalgia, and Lyme disease, they’re frequently misdiagnosed or missed entirely. If no one has tested your blood for mycotoxin antibodies, your evaluation may not be complete.

Why Blood Serum Testing Matters
Most mycotoxin testing in the U.S. relies on urine samples. MyMycoLab tests blood serum and that difference changes what your results can tell you.
Urine testing detects mycotoxin metabolites, but low levels of mycotoxins are naturally present in everyday foods like coffee, grains, and nuts. Meaning urine results can reflect what you ate, not whether your body is being harmed. Blood serum testing measures your immune system’s actual response: the IgG and IgE antibodies your body produces when it recognizes mycotoxins as a threat.
Blood Serum Testing
Urine Testing (Other Labs)
What it measures
IgG and IgE antibodies — your immune system's response to mycotoxin exposure
Free mycotoxin metabolites — the toxin compounds passing through your body
What results tell you
Whether your body has mounted an immune reaction to specific mycotoxins — indicating meaningful exposure
Whether mycotoxin compounds are present in your urine at the time of collection
Ochratoxin A detection
Reliable. Detected through antibodies in the blood
Unreliable. 99.8% of ochratoxin binds to albumin and is reabsorbed by the kidneys, making urinary excretion negligible
Dietary mycotoxin interference
Not a factor. Antibodies reflect immune response, not food intake
Can be misleading. Can detect traces from everyday foods (cereals, coffee, nuts, wine), even in healthy individuals
Exposure vs. presence
Distinguishes between real immune exposure and incidental contact
Detects presence but cannot differentiate between dietary intake and environmental exposure
Antibody types
Tests both IgG (ongoing/past exposure) and IgE (allergic sensitization) for each mycotoxin
Not applicable. Urine testing does not measure immune response
Number of mycotoxins tested
14 mycotoxins with both IgG and IgE — delivering 28 individual results
Typically, 11–16 mycotoxins, varies by laboratory
Clinical validation
Serum antibody methodology validated in peer-reviewed research for over 20 years
Methodology varies by lab; the CDC has noted limitations of urine-based mycotoxin testing for clinical diagnosis
14 Mycotoxins.28 Results.
Our blood serum panel tests for IgG and IgE antibodies to each of the 14 mycotoxins below — giving you 28 individual data points that reveal how your immune system is responding to mycotoxin exposure.
Every mycotoxin tells a different story about what’s happening in your body. Our panel tests for all 14 — with both IgG and IgE antibodies — so nothing gets overlooked.
One of the most potent mycotoxins known. Satratoxin is neurotoxic, damages olfactory neurons, and triggers chronic inflammation in the brain. Patients exposed to it commonly report fatigue, headaches, nosebleeds, and persistent cognitive problems.
Potent protein synthesis inhibitors that disrupt how your cells build and repair themselves. Exposure is associated with tremors, immune suppression, and widespread inflammation throughout the body.
Among the most widespread and dangerous mycotoxins. Ochratoxin is toxic to the kidneys, liver, and brain, classified as a possible human carcinogen, and crosses the placenta. Nearly 99.8% binds to albumin in the blood — which is why it’s virtually undetectable in urine testing.
The only mycotoxin that has been used in biological warfare. T-2 toxin damages the gut lining, disrupts reproductive cycles, and is known to decrease testosterone levels in both men and women.
Destroys intestinal barrier function, which can lead to symptoms resembling IBS, celiac disease, and chronic inflammatory bowel conditions. Also known to affect both estrogen and testosterone balance.
Cladosporium spores are one of the most common airborne allergens and significantly affect people with asthma or respiratory conditions. This mold also produces neurotoxic volatile compounds linked to severe headaches, seizures, and excessive sleepiness.
A broad class of trichothecene toxins that affect multiple body systems at once. Linked to nerve demyelination, pulmonary hemorrhage, skin reactions, hormonal disruption, and digestive damage including intestinal permeability.
Toxic at the cellular level — mutagenic, genotoxic, and immunosuppressive. Alternaria toxin generates reactive oxygen species that drive chronic inflammation and is also known to reduce testosterone levels.
A hemolytic mycotoxin, meaning it destroys red blood cells. It is also cytotoxic to key immune cells including neutrophils and macrophages, weakening your body’s front-line defense against infection.
A precursor to aflatoxin and a recognized carcinogen. Sterigmatocystin is mutagenic, toxic to the liver, and teratogenic — meaning it can cause developmental harm during pregnancy. Also linked to autoimmune disease.
A powerful immunosuppressant — so much so that a synthetic version is used as an anti-rejection drug for organ transplants. Environmental exposure to this mycotoxin can weaken your immune system’s ability to fight infection and regulate itself.
One of the most immunotoxic mycotoxins. Gliotoxin kills white blood cells at extremely low concentrations, damages DNA, and has been linked to neurological conditions including multiple sclerosis. It also compromises blood-brain barrier integrity.
Toxic to the liver and kidneys, and a known cause of esophageal cancer. Fumonisin disrupts sphingolipid metabolism in the brain and can cause depression that doesn’t respond to standard antidepressant medication. Also linked to mitochondrial dysfunction.
An estrogenic mycotoxin that mimics estrogen in the body. In women, it can cause premature breast development, early puberty, reduced fertility, and lower milk production. In men, it reduces testosterone and sperm production. Also hepatotoxic and immunotoxic.
