Allergens, Pediatric, Common Profile IgE
Also known as: COMPEDPRO
Use
The Allergens, Pediatric, Common Profile IgE test is intended to evaluate the presence of allergen-specific immunoglobulin E (IgE) antibodies in pediatric patients. It assesses sensitivity to common allergens including cat dander, dog dander, cockroach, Alternaria alternata, and various food items like egg white, milk, peanut, soybean, wheat, and codfish. The presence of elevated IgE can aid in the diagnosis of allergic conditions, although the levels may not always correlate with the severity of allergic symptoms or reactions.
Special Instructions
Multiple patient encounters should be avoided. It is recommended to collect serum in a separator tube, and multiple specimen tubes should be avoided. Serum should be separated from cells as soon as possible or within two hours of collection. Transfer 1.35 mL of serum to the appropriate transport tube, ensuring the minimum volume of 0.69 mL is met.
Limitations
Allergen results, particularly in the range of 0.10-0.34 kU/L, are primarily for specialist evaluation as their clinical relevance can be undetermined. Despite the correlation of increasing IgE levels with higher sensitivity to allergens, these do not always predict clinical reactions or correlate with skin test results. Clinical correlation with patient history and reactivity to specific allergens is essential. Negative results do not exclude the possibility of allergies or severe allergic reactions like anaphylaxis.
