Why This Test Might Be Ordered

Your healthcare provider may recommend this test if you’ve been exposed to mold environments, have symptoms like nausea, vomiting, or skin irritation, or if you live/work in areas with known mold contamination. It’s also used in occupational settings where workers may handle moldy materials.

What to Expect During the Test

You’ll provide a blood sample, usually drawn from a vein in your arm. The sample will be sent to a lab for analysis using a sensitive detection method to measure trichothecene levels.

Sample Collection and Preparation

No special preparation is needed for this test. However, if you’re taking certain medications or have a history of bleeding disorders, let your provider know before the test.

What the Results Mean

Results show whether trichothecenes are present in your blood. Elevated levels may indicate recent exposure to mold toxins, but interpretation depends on clinical context, including your symptoms and exposure history.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Trichothecenes are potent toxins linked to acute poisoning (e.g., vomiting, diarrhea) and chronic effects like skin rashes or immune system disturbances. While rare, high exposure can be dangerous, so prompt evaluation is important if levels are elevated.
