The Isocyanate TDI Allergy Test is a blood test that checks for an immune response to toluene diisocyanate (TDI), a chemical used in polyurethane foams, coatings, and adhesives. It is ordered when a person has workplace or hobby exposure to TDI and symptoms such as wheezing, nasal congestion, or skin reactions. The test helps a clinician evaluate whether symptoms may be related to TDI sensitivity.

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.

Who it is for

It is usually ordered by an allergist, occupational medicine physician, or primary care clinician for people who work with isocyanates or have symptoms after exposure.

Preparation

No fasting is required. Tell the clinician about all medicines, especially antihistamines, because some can affect allergy test results.

Results and what they mean

Results are reported as positive, negative, or a numeric level for each marker. A positive result does not by itself diagnose an allergy or asthma; a clinician interprets it with your symptoms and exposure history. This is general information, not medical advice.

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.
