About this test

Mucor racemosus is a mold, and this test measures IgE antibodies to it in your blood. It is found in soil, compost, and spoiled produce, and indoors in very damp spots. A positive result shows sensitization, which is not the same as an allergy. No fasting or other prep is needed.

For adults 18 and older. Test availability varies by lab location.

Who should take this test?

For adults who want to check for sensitization to the mold Mucor racemosus, often when symptoms flare in damp spaces or during mold season, or before seeing an allergist.

What does this test measure?

The result shows whether you are sensitized to Mucor racemosus. With your history, it can help a healthcare provider decide whether further evaluation makes sense.

Mucor racemosus-specific IgE (m4)
This marker measures IgE antibodies to the mold Mucor racemosus. A level above the lab’s reference range shows the immune system is sensitized to it. Many sensitized people have no symptoms, so the result is read with your history.
Why it’s measured: Helps a healthcare provider see whether Mucor racemosus may play a part in symptoms.

What your results tell you

The lab reports an IgE level in kU/L and compares it with its reference range. A level above that range means you are sensitized.

Questions

Common questions.

Anything else, our care team answers by phone, text, or email.

It does not tell you whether you will react to Mucor racemosus, or how strongly. IgE shows sensitization, and many sensitized people have no symptoms. A negative result does not clear an allergy either.

Decisions about mold exposure or care belong with an allergist or other healthcare provider who knows your history.

No. This test measures IgE antibodies to Mucor racemosus in your blood. It does not measure mold in your home or workplace, and it is not a test for mold toxins.

A positive result shows sensitization to this mold, which an allergist or other healthcare provider reads with your symptoms and where they happen.

Mucor racemosus is found in soil, compost, and spoiled produce, and indoors in very damp spots. Molds release spores into the air, and those spores carry the allergens this test looks at.

Knowing where a mold grows can help you and a healthcare provider think about when and where symptoms happen. A result alone does not show where your exposure comes from.

Yes. Mucor racemosus is one of the allergens in the indoor allergy panel, which measures IgE to several common indoor allergens in one draw.

Panel results are read like single tests. Sensitization is not the same as allergy.

Lab tests are informational and don’t diagnose conditions on their own. Available to adults 18 and older; test availability varies by lab location. A licensed clinician reviews your order and, if appropriate, orders the test. All testing is performed at CLIA-certified laboratories.
