The Phoma Betae Allergy Test measures blood levels of IgE antibodies specific to Phoma betae, a mold that grows on sugar beets and can be found in soil and decaying plant matter. It is ordered when a person has allergy symptoms and a clinician suspects mold exposure as a trigger.
What it measures
- Total IgE — Overall level of allergy-related antibodies in the blood.
- Phoma betae-specific IgE — Antibodies that bind specifically to Phoma betae mold.
- Other mold-specific IgE — Sometimes checked to compare reactions to common molds.
Who it is for
A clinician such as an allergist or primary care provider may order this test for people with ongoing sneezing, runny nose, or asthma symptoms that could be linked to mold exposure.
Preparation
No fasting or special preparation is required. A blood sample can be drawn at any time of day.
Results and what they mean
Results are reported as a number or class for Phoma betae-specific IgE, often alongside total IgE. A clinician interprets these values with your symptoms and history; a positive result alone does not confirm an allergy. This is general information, not medical advice.
