The Rhizopus nigricans Allergy Test measures allergic sensitization to a common mold. It is ordered when a person has persistent allergy symptoms and a clinician suspects mold as a trigger.

What it measures

  • Specific IgE to Rhizopus nigricans — Antibody level linked to allergic response to this mold.
  • Total IgE — Overall allergy antibody level, sometimes included for context.
  • Other mold IgEs — Often tested together to check for cross-reactivity or multiple mold allergies.

Who it is for

Allergists, immunologists, or primary care clinicians order this test for people with ongoing sneezing, runny nose, or asthma symptoms that may worsen in damp or moldy environments.

Preparation

No fasting or special preparation is required. Tell your clinician about antihistamines or other medications you take, as they may affect test interpretation.

Results and what they mean

Results are reported as a numerical level or class for specific IgE, often with a reference range. A higher level suggests sensitization but does not by itself diagnose an allergy. A clinician interprets results with your history and symptoms. This is general information, not medical advice.

Requesting the Rhizopus Nigricans 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. Access across Pacific is uneven, so confirming a site ahead of time is worthwhile.

Frequently asked questions

What is Rhizopus nigricans?

Does a positive result mean I am allergic?

Not necessarily. It shows your immune system has made antibodies to the mold, but only a clinician can confirm an allergy.

How long do results take?

Can I take allergy medication before the test?

Ask your clinician. Some medications may need to be stopped, but do not change any medication without medical advice.
