The Penicillium Chrysogenum Allergy Test is a blood test that checks for an allergic response to Penicillium chrysogenum, a common mold found indoors and outdoors. It is ordered when a person has symptoms such as sneezing, coughing, or wheezing that may be linked to mold exposure.
What it measures
- Specific IgE antibodies to Penicillium chrysogenum — Your immune system makes these antibodies if you are sensitized to this mold.
- Total IgE — A measure of all allergy-related antibodies in your blood, which can help interpret the specific result.
- Other mold-specific IgE — Sometimes tested together to see if you react to multiple molds.
Who it is for
This test is usually ordered by an allergist or primary care clinician for people with ongoing allergy or asthma symptoms that might be triggered by mold.
Preparation
No fasting or special preparation is needed. You can eat and drink normally before the blood draw.
Results and what they mean
Results are reported as a number that shows the level of specific IgE to Penicillium chrysogenum. A clinician interprets this number along with your symptoms and history; it does not by itself diagnose an allergy or predict severity. This is general information, not medical advice.
