Cheese, Mold Type Allergy Testing in California

This blood test checks for allergic sensitivity to molds found in certain cheeses, especially blue-veined types like Roquefort, Gorgonzola, and Brie. It is usually ordered when a person has allergy symptoms after eating cheese or handling moldy foods, and the cause is unclear.

What it measures

Specific IgE to mold allergens — Antibodies your immune system makes against mold proteins; higher levels suggest sensitivity.
Total IgE — A general measure of allergic antibody in your blood, used for context.
Individual mold species markers — Separate results for molds such as Penicillium or Aspergillus, common in cheese rinds.
Cross-reactive markers — Checks whether your reaction may relate to other molds or foods.

Who it is for

A doctor or allergist typically orders this test when someone reports hives, nasal symptoms, wheezing, or digestive upset after eating mold-ripened cheese. It may also be used to help sort out food allergy from other causes.

Preparation

No fasting is needed. Tell your clinician about all medicines you take, since some antihistamines can affect allergy test results.

Results and what they mean

Results are reported as levels of specific IgE, often graded from negative to high, along with a reference range from the lab. A clinician interprets these numbers together with your symptoms and history; a positive result alone does not always mean you are allergic. This is general information only and not medical advice.

Frequently asked questions

Do I need to avoid cheese before the test?

No. It shows sensitivity to certain mold proteins. Many people tolerate some cheeses and react to others.

Can this test diagnose a cheese allergy on its own?

No. Results must be reviewed with your symptoms and medical history by a clinician.

How long until I get results?

Typical turnaround is 1 to 3 business days, though it can vary by lab.
