Allergen, Epidermals and Animal Proteins, Cat Dander
Also known as: CATEPI
Use
This test is used to detect allergen-specific IgE antibodies to cat dander, which can help diagnose allergic reactions in patients who have symptoms of allergy particularly related to feline exposure. It assists in identifying individuals with a sensitization to cat allergens which might manifest as respiratory allergies or skin reactions. It is important for making informed clinical decisions regarding patient management and therapeutic interventions for allergy symptoms.
Special Instructions
Not provided.
Limitations
This assay measures the concentration of IgE antibodies specific to cat dander, but it might not directly correlate with clinical symptoms or in vivo reactivity. Low levels of IgE (0.10-0.34 kU/L) have undetermined clinical relevance and should be interpreted in conjunction with the patient’s clinical history and other diagnostic tests. False negatives can occur, and a negative result does not definitively rule out cat allergen sensitivity or the risk of anaphylaxis.
