What is this test?
This blood test looks for allergen-specific IgE antibodies directed against Alternaria farinae, a mold commonly found in damp indoor and outdoor environments. A qualitative result reports whether these antibodies were detected.
Why might I need this test?
Your clinician may order this test if you have sneezing, wheezing, congestion, or eye symptoms that may be related to mold exposure. It can help identify whether Alternaria farinae is a potential trigger of your symptoms.
How is the test performed?
A blood sample is analyzed for IgE antibodies to Alternaria farinae. The laboratory provides a qualitative result indicating whether specific antibodies were detected.
How do I prepare for the test?
This test usually requires no special preparation. Tell your clinician about any medicines you take, and do not stop prescribed medications unless your clinician advises you to do so.
Reference range
Adult males: 7-56 U/L; Adult females: 7-43 U/LN/A
No special preparation required. Avoid fatty meals before the test if possible.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
A positive result indicates that the immune system has produced IgE antibodies to Alternaria farinae, consistent with sensitization to this mold. This may help explain allergy symptoms when the result matches your exposure history and symptoms. A negative result does not completely exclude mold allergy because some affected people may have low antibody levels or symptoms caused by another trigger.
Short name
Alternaria farinae IgE
