Hexamethylene Diisocyanate (HDI) Allergy Test in Nebraska

The hexamethylene diisocyanate (HDI) allergy test is a blood test that checks for antibodies your immune system may make after exposure to HDI, a chemical used in some paints, coatings, and foams. It is usually ordered when a person has workplace exposure and symptoms such as wheezing, coughing, or skin reactions that could be related to HDI.

What it measures

HDI-specific IgE — An antibody linked to immediate-type allergic reactions to HDI.
HDI-specific IgG — An antibody that can show immune exposure to HDI, though it does not by itself confirm allergy.
Total IgE — A general measure of allergic antibody levels, sometimes included for context.
Serum control — A check that the sample was handled properly and the test ran correctly.

Who it is for

This test is typically ordered by allergists, occupational medicine clinicians, or primary care clinicians for people who work with HDI-containing products and have symptoms that may be work-related.

Preparation

No fasting is required. Tell your clinician about any medicines you take, because some drugs may affect antibody levels; timing may matter if symptoms are recent.

Results and what they mean

Results are usually reported as negative or positive, sometimes with a numeric level for each antibody. A positive result does not prove allergy by itself, and a negative result does not rule it out, so a clinician interprets the results alongside your history and exam. This is general information, not medical advice.
