Use

The Allergen, Food, Crab test is used to detect and quantify allergen-specific immunoglobulin E (IgE) for Crab, which helps assess the potential for IgE-mediated allergic reactions in patients. It is important for evaluating allergic sensitivity to crab, particularly in individuals with suspected food allergies. The results can assist healthcare providers in forming a comprehensive clinical evaluation when correlated with patient history and in vivo reactivity tests.

Special Instructions

Multiple patient encounters should be avoided to ensure accurate testing. It is crucial to separate serum from cells as soon as possible, ideally within two hours of collection. For multiple allergen orders, refer to 'Allergen Specimen Collection Instructions' at the designated web resource.

Limitations

While increasing concentrations of allergen-specific IgE are reflective of increasing allergen burden, these concentrations do not always correlate directly with the severity of clinical allergic reactions or skin testing outcomes. A negative test result does not definitively exclude a clinical allergy or the possibility of anaphylaxis. It is necessary to correlate the laboratory results with clinical history and in vivo reactivity to specific allergens to fully assess the allergic status.
