What it measures
- TDI-specific IgE — An antibody that, if present, suggests the immune system has reacted to TDI.
- Total IgE — A general measure of allergic antibody levels; helps interpret the specific result.
- TDI-specific IgG — An antibody that may indicate past or ongoing exposure rather than allergy.
- Exposure history — Information about tasks, duration, and protective equipment used at work or home.
Preparation
No fasting is required. Tell the clinician about all medicines, especially antihistamines, because some can affect allergy test results.

Frequently asked questions
Do I need to stop my allergy medicine before this test?
Ask the clinician ordering the test. Some antihistamines can interfere with allergy testing, but the decision depends on your medicines and health history.
How soon will I get results?
Typical turnaround is 1 to 3 business days after the blood sample reaches the lab.
Can this test tell me if I have asthma?
No. It only checks for immune sensitivity to TDI. Asthma and other breathing conditions are diagnosed by a clinician using symptoms, exams, and breathing tests.
Is a positive result permanent?
Sensitivity can persist, but results should be interpreted with your exposure and symptoms. Discuss what a positive result means for your situation with a clinician.
