Test ID: PEANT    
Peanut, IgE with Reflex to Peanut Components, IgE, Serum

Useful For Suggests clinical disorders or settings where the test may be helpful

Evaluation of patients with suspected peanut allergy

 

Evaluation of patients with possible peanut cross-reactivity

Highlights

The determination of the relative amount of IgE antibody to total peanut, and IgE antibodies to specific peanut components, can aid in assessment of the potential strength and type of allergenic response to peanuts.

 

IgE antibody to total peanut extract will be tested.

 

If detectable total peanut IgE antibody is present, additional specific peanut allergen antibody testing will be performed. This is comprised of testing for IgE antibodies to the potential allergens Ara h 2, Ara h 1, Ara h 3, Ara h 6, Ara h 8, Ara h 9, and profilin Bet v2.

Testing Algorithm Delineates situations when tests are added to the initial order. This includes reflex and additional tests.

Testing begins with analysis of peanut IgE. If peanut IgE is negative (<0.10 kU/L), testing is complete.

 

If peanut IgE is 0.10 kU/L or greater, then 7 peanut components (Ara h 2, Ara h 1, Ara h 3, Ara h 6, Ara h 8, Ara h 9, and profilin Bet v2) are performed at an additional charge.
