Order Isocyanate TDI Allergy Test | ChemicalIsocyanate TDI is a reactive chemical used in the production of polyurethane foams, coatings, adhesives, and elastomers. Because it can act as a sensitizer, repeated or single high-level exposure may prompt an immune response in susceptible individuals. The Isocyanate TDI Allergy Test measures specific IgE antibodies in the blood to help assess whether a person has become sensitized to toluene diisocyanate.
About Isocyanate TDI Allergy Test | Chemical in Evanston
This test evaluates immunoglobulin E (IgE) antibodies directed against toluene diisocyanate (TDI), a common industrial isocyanate.
IgE is an antibody class associated with immediate-type allergic reactions. When a person is exposed to an allergen such as TDI, the immune system may produce IgE antibodies that bind to the chemical structure. A blood test can detect these antibodies and provide an objective measure of sensitization.
The Isocyanate TDI Allergy Test is typically ordered when a healthcare provider suspects work-related or environmental exposure to isocyanates and wants to investigate whether symptoms such as wheezing, nasal congestion, or skin irritation are linked to an allergic response. It is not a standalone diagnostic tool; results are interpreted alongside clinical history and other findings.
Toluene diisocyanate is one of several isocyanates, and cross-reactivity with other isocyanates can occur. A positive result indicates the presence of specific IgE antibodies but does not by itself confirm that symptoms are caused by TDI. Conversely, a negative result does not entirely rule out isocyanate sensitivity, as some reactions may involve non-IgE mechanisms.
