About this test

The Peanut Allergy Test (Moongfali) is a specialized blood test used to detect allergic sensitivity to peanuts by measuring specific Immunoglobulin E (IgE) antibodies. Peanut allergy is one of the most common and potentially severe food allergies. Even small amounts of peanut exposure may trigger allergic reactions in sensitive individuals. Symptoms can range from mild itching and skin rashes to life-threatening anaphylaxis.

This test helps determine whether the immune system reacts abnormally to peanut proteins and assists healthcare providers in diagnosing peanut allergy accurately. Early identification allows individuals to avoid allergens and reduce the risk of severe allergic episodes.

Benefits of the Test

  • Accurately detects allergic sensitivity to peanuts.
  • Helps diagnose food-related allergic reactions.
  • Assists in preventing severe allergic responses.
  • Supports personalized dietary and treatment plans.
  • Useful for identifying triggers causing unexplained symptoms.
  • Helps distinguish peanut allergy from food intolerance.
