Isocyanate MDI Allergy Test in Idaho

The Isocyanate MDI Allergy Test is a blood test that checks for allergic sensitization to methylene diphenyl diisocyanate (MDI), a chemical used in polyurethane foams, coatings, and adhesives. It is ordered when a person has work-related or home-related symptoms such as wheezing, nasal congestion, or skin reactions after exposure to MDI-containing products.

What it measures

MDI-specific IgE — Antibody that may indicate allergic sensitization to MDI.
Total IgE — Overall allergy antibody level, sometimes used for context.
Other isocyanate IgEs — Related isocyanates such as TDI or HDI may be checked together.
Inhalant allergen panel — Common airborne allergens may be tested to rule out other causes.

Who it is for

It is usually ordered by allergists, occupational medicine physicians, or primary care clinicians for people with suspected MDI-related allergy, especially those working with paints, foams, or adhesives.

Preparation

No fasting is required. Tell your clinician about all medicines, especially antihistamines, because some can affect allergy test results.

Results and what they mean

Results are reported as negative or positive, often with a numeric level for MDI-specific IgE. A positive result suggests sensitization but does not by itself mean you have an allergy or predict how severe symptoms will be. A clinician interprets the results alongside your symptoms and exposure history. This is general information, not medical advice.

Frequently asked questions

Do I need to stop my allergy medicine before this test?

Some antihistamines can affect allergy testing. Ask your clinician whether you should pause them and for how long.

What does a positive result mean?

It means your blood has antibodies that react to MDI. Your clinician will consider your symptoms and exposure to decide what it means for you.

Can this test tell me if my workplace caused my symptoms?

It can show sensitization, but it cannot prove where or when exposure happened. Your work history and symptom pattern help clarify that.

How long until I get results?

Typical turnaround is 1 to 3 business days after the sample reaches the lab.
