Allergen, Fungi and Molds, Staphylococcal Enterotoxin A IgE
Also known as: STAPHA IGE
Use
This test measures allergen-specific IgE antibodies to Staphylococcal Enterotoxin A in human serum using a quantitative ImmunoCAP fluorescent enzyme immunoassay. Elevated allergen-specific IgE levels can indicate sensitization to the specific allergen and may correlate with the potential for allergic reactions. Interpretation of results should be in conjunction with clinical history and other allergy test results.
Special Instructions
Not provided.
Limitations
The clinical relevance of allergen results in the range of 0.10-0.34 kU/L is undetermined and intended for specialist interpretation. Concentrations of allergen-specific IgE may not correlate with the severity of clinical symptoms or skin test responses. Negative results do not conclusively rule out clinical allergy or anaphylaxis.
