Allergen, Fungi and Molds, Staphylococcal Enterotoxin B IgE
Also known as: STAPHB IGE
Use
This test is clinically significant for identifying allergen-specific IgE antibodies against Staphylococcal Enterotoxin B. It aids healthcare providers in diagnosing allergic responses to this specific allergen. Increasing levels of allergen-specific IgE may indicate heightened sensitivity to the specific allergen, but the correlation with clinical symptoms and skin testing must be considered. Results between 0.10-0.34 kU/L require specialist interpretation as clinical relevance is undetermined. It is important to correlate laboratory results with the patient's clinical history and in vivo reactivity to specific allergens.
Special Instructions
Multiple patient encounters should be avoided to ensure accurate test results. Proper specimen collection and handling according to specified guidelines are essential for test validity.
Limitations
Concentrations of allergen-specific IgE do not directly correlate with the degree of clinical response. A negative test result does not rule out the possibility of a clinical allergy or anaphylaxis. The results should be interpreted in the context of clinical history and other diagnostic tests, as they may not align with skin testing outcomes.
