Order Isocyanate TDI Allergy Test | ChemicalIsocyanate TDI allergy testing measures the presence of immunoglobulin E (IgE) antibodies directed against toluene diisocyanate, a reactive chemical widely used in the production of polyurethane foams, coatings, adhesives, and elastomers. Because TDI is a known respiratory sensitizer, identifying an IgE-mediated response can help clarify whether symptoms such as wheezing, nasal congestion, or skin reactions are linked to chemical exposure.
About Isocyanate TDI Allergy Test | Chemical in Appleton
Toluene diisocyanate is one of the most common isocyanates in industrial settings, and IgE sensitization to it is a recognized occupational concern.
TDI is a low-molecular-weight chemical that becomes allergenic when it binds to proteins in the body, a process called haptenization. Once sensitized, the immune system produces specific IgE antibodies that can trigger responses upon re-exposure, even at low concentrations.
Exposure to TDI occurs primarily through inhalation of vapors or aerosols, and to a lesser extent through skin contact. Workplaces that handle polyurethane raw materials, spray foams, and certain paints or varnishes may present relevant exposure routes. Symptoms of sensitization can include asthma-like breathing difficulty, rhinitis, and contact dermatitis.
This test detects TDI-specific IgE in a blood sample. A positive result indicates that IgE antibodies to TDI are present, which supports a diagnosis of sensitization but does not by itself predict the severity of future reactions. Results should be interpreted alongside exposure history and clinical findings by a qualified healthcare provider.
