Quick answer
The TDI Allergy Test detects IgE antibodies against toluene diisocyanate, a volatile isocyanate used mainly to produce flexible polyurethane foam. TDI is a recognized cause of occupational asthma, and symptoms may begin after weeks or months of exposure. The test helps show whether an allergic sensitization to TDI is present when work-related symptoms are being investigated.
What this test measures
Toluene diisocyanate, or TDI, is a reactive chemical used in flexible foams for furniture, mattresses, and automotive seating. It can also be present in coatings and sealants. Because TDI can become airborne during production and handling, inhalation is a common route of exposure.
The test measures specific IgE antibodies to TDI from a blood sample. A positive result shows sensitization, which is more likely with repeated exposure. Some people develop asthma-like symptoms after sensitization, while others remain without symptoms, so results are interpreted with the clinical history.
People who manufacture or handle flexible foam, or who work with TDI-based products, may be tested when they report wheezing, cough, chest tightness, or skin irritation that appears at work. A qualified healthcare provider should interpret the result and consider breathing tests or other evaluation.
