What it measures
- Specific IgE to hexamethylene diisocyanate (HDI) — Reflects the presence of allergic antibodies directed against HDI.
What the test involves
A healthcare professional collects a small sample of blood from a vein in your arm using a standard blood draw. The sample is then sent to a laboratory for analysis.
Why it is often ordered
