Why This Test Is Done

Your healthcare provider may order this test if you’ve had prolonged exposure to mold, have symptoms like skin rashes, respiratory issues, or immune system problems, or if you live in an area with known mold contamination.

What to Expect Before the Test

No special preparation is needed. You’ll provide a blood sample, typically drawn from a vein in your arm. The process is quick and usually painless.

What the Results Mean

Results help determine if trichothecene exposure is present. Elevated levels may indicate recent or ongoing exposure that requires further evaluation or treatment.

Possible Symptoms of Exposure

Symptoms of trichothecene exposure can include skin irritation, respiratory distress, gastrointestinal issues, or weakened immune function. These symptoms may appear shortly after exposure or develop gradually.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Clinical Significance: Trichothecenes are mycotoxins produced by certain molds. High levels in the blood can indicate recent or chronic exposure, which may require medical intervention to manage symptoms or reduce further risk.
