Isocyanate HDI

This test measures specific antibodies in your blood to see if your immune system reacts to Hexamethylene Diisocyanate (HDI), a chemical used in industrial paints and foams. It helps show whether breathing problems or skin irritation may be caused by an allergic reaction to this substance, which is often related to workplace exposure. By identifying this specific sensitivity, the test helps distinguish occupational allergies from other types of asthma or dermatitis. However, a positive result indicates sensitization and does not confirm a diagnosis of occupational asthma without a full medical evaluation.
