Red Kidney Bean IgE
The Red Kidney Bean (f287) IgE test measures your body's allergic response to red kidney beans by quantifying IgE antibodies. This test is performed in a lab and helps in diagnosing food allergies when combined with other clinical evaluations.  Food-specific IgE tests are very sensitive but a positive result doesn't always mean you'll have allergic reactions to the food. A healthcare provider should evaluate these results alongside your medical history to accurately diagnose a food allergy.

  • Widespread skin disease
  • Recent use of antihistamines or other medications
  • Uncooperative patients
