Can RAST testing determine pet allergies?

0

My boyfriend has a cat that I am convinced is giving me a serious allergic reaction. I am not generally allergic to cats or other pets, but it’s the only thing that makes sense to me. Can RAST testing determine pet allergies?

Hi there,

Thanks for your question.

Radioallergosorbent testing or RAST is a method employed in allergy testing (type 1 allergy – IgE mediated). The patient’s serum is incubated with a solid phase allergen and the amount of allergen-specific IgE quantified with radiolabelled anti-IgE. Many different allergens (e.g. house dust mite, grass pollen, cat epithelium) may be tested for with one sample of serum. Although the RAST was the first type of test described, radioisotopes are no longer used in the detection of specific IgE and hence the term RAST is now used as an abbreviation for an in vitro assay for specific IgE.
