# Isocyanate MDI

> This test measures specific antibodies in your blood that react to Methylene Diphenyl Diisocyanate (MDI), a chemical commonly used in industrial foams, paints, and glues. It helps show whether your immune system has become overly sensitive to this substance, which is useful for evaluating breathing problems or skin reactions that occur in the workplace.
