Order Hexamethylene Diisocyanate (HDI) Allergy Test | ChemicalThe HDI (Hexamethylene Diisocyanate) Allergy Test is a blood-based immunoassay that measures circulating immunoglobulin E (IgE) antibodies directed against hexamethylene diisocyanate, a reactive chemical widely used in industrial coatings, adhesives, and foams. Unlike patch testing, which assesses delayed hypersensitivity, this test evaluates the immediate-type allergic response that can follow sensitization to isocyanates.
About Hexamethylene Diisocyanate (HDI) Allergy Test | Chemical in Paramount
Isocyanates are among the most common causes of occupational asthma and chemical sensitization in the workplace.
Hexamethylene diisocyanate belongs to the isocyanate family, a group of highly reactive compounds used in the production of polyurethane paints, varnishes, sealants, and rigid or flexible foams. Because HDI is volatile at ambient temperatures, inhalation and skin contact are the primary routes of exposure in industrial settings.
Sensitization to HDI occurs when the immune system produces specific IgE antibodies after repeated exposure. Once sensitized, even low-level contact can provoke symptoms such as wheezing, nasal congestion, watery eyes, or contact dermatitis. The IgE antibody response measured by this test is distinct from the irritant effects that can occur in anyone exposed to high concentrations of the chemical.
This assay uses a blood sample, so it does not require the controlled exposure that provokes symptoms in some patients. Results are reported as a quantitative or semi-quantitative IgE level for HDI. A positive result supports the presence of specific IgE antibodies and is interpreted by a qualified clinician alongside exposure history, symptom timing, and other diagnostic findings.
