There is no single test for mold toxicity. Testing for mold can be tricky because there are so many different types of molds, and each person may react differently to exposure. Some doctors may test your blood for antibodies to certain molds, or order a sputum culture to look for certain molds in your lungs. There are also some tests that can be done to measure the level of inflammation in your body, as well as tests to measure the level of toxins in your blood or urine. However, there is no one "standard" test that can accurately diagnose mold toxicity.

There is no one definitive test for mold toxicity. A variety of tests may be used, including blood tests, urine tests, and imaging tests. If a person suspects they have a mold allergy or mold toxicity, the first step is usually to get tested for IgE antibodies to common molds. This can be done with a blood test. If IgE antibodies are found, it's likely the person has an allergy to mold. If a person has symptoms that suggest they may have mold toxicity, but no IgE antibodies are found, further testing may be needed. Urine testing can look for compounds called mycotoxins that are produced by some types of molds.
