The Aspergillus niger allergy test is a blood test that checks whether your immune system reacts to Aspergillus niger, a common mold found in soil, dust, and some foods. It is usually ordered when a person has ongoing allergy or asthma symptoms and a clinician wants to see whether this mold may be a trigger.

What it measures

  • Specific IgE to Aspergillus niger — Measures the allergy-related antibody your immune system makes against this mold.
  • Total IgE — Sometimes measured to give context, since this antibody is often higher in allergic people.
  • Other mold IgE tests — May be ordered alongside to compare reactions to different molds.
  • Inhalant allergen panel — A group of common airborne allergens that may be checked at the same time.

Who it is for

A clinician such as an allergist, immunologist, or primary care provider typically orders this test. It is most often used for people with persistent nasal, eye, or breathing symptoms that may be linked to mold exposure.

Preparation

No fasting or special preparation is needed for this blood test. You can eat, drink, and take your usual medicines unless your clinician tells you otherwise.

Results and what they mean

Results are reported as a level of specific IgE, often shown as a number or a class from low to high. A clinician interprets this together with your symptoms, exposure history, and other tests; a single result does not confirm or rule out an allergy. This is general information only and not medical advice.

Requesting the Aspergillus niger Allergy Test in California

Order online, choose a certified collection site in California, and review results through a secure portal. No referral is required, and orders are processed confidentially. Because the region is uneven, coastal metros, inland towns, and rural counties with very different access to testing — worth planning around when you book.

Frequently asked questions

Do I need to avoid mold before the test?

No. Avoiding mold is not required for the test, and the result reflects your immune response rather than your recent exposure.

Does a positive result mean I am allergic?

Not always. A positive result shows sensitivity, but a clinician decides whether it explains your symptoms.

Can this test diagnose a mold infection?

No. It checks for allergy-related antibodies, not an active infection.

How long do results take?

Most results are ready in about 1 to 3 business days, though timing can vary by lab.
