About the Isocyanate TDI Allergy Test - Chemical
The isocyanate TDI allergy test is a blood test that measures immunoglobulin E (IgE) antibodies against toluene diisocyanate (TDI), a reactive chemical used to make polyurethane foams, coatings, adhesives, and sealants. It helps determine whether exposure to TDI is contributing to allergy symptoms such as sneezing, nasal congestion, wheezing, coughing, or skin irritation. Isocyanate exposure is a recognized concern in industries that handle these chemicals, and symptoms often appear or worsen at work. The test is typically ordered for workers with recurring symptoms after handling isocyanate products.
Who this test may be right for
- Workers in foam, coating, adhesive, and sealant manufacturing.
- Spray painters and autobody technicians exposed to isocyanate products.
- People with asthma or rhinitis that worsens during or after work shifts.
- Those being evaluated for suspected occupational isocyanate allergy.
What this test measures
- TDI (toluene diisocyanate)-specific IgE Detects IgE antibodies that bind to toluene diisocyanate allergens in the blood.
Before your visit
- No fasting is required.
- Tell the clinician about antihistamines and any other allergy medications.
- Continue prescribed medications unless a healthcare provider advises otherwise.
- Wear a short-sleeved or loose top for the blood draw.
Understanding your results
A positive result suggests the body has produced IgE antibodies to TDI, which may indicate a sensitivity contributing to nasal, eye, or airway symptoms after exposure. A negative result makes TDI allergy less likely but does not exclude irritation or reactions to other isocyanates. Because symptoms are often work-related, tracking when they occur can help interpretation. Discuss results with a healthcare provider for a complete assessment.
