TOTAL IMMUNOGLOBULIN E (IgE)

"This test measures total IgE levels in the blood, which are associated with allergic responses. It is essential when investigating suspected allergies, asthma, eczema, hay fever, or unexplained skin rashes. Elevated IgE levels may indicate an allergic tendency and can help guide further allergy testing or specialist referral when symptoms are persistent or worsening.

Preparation: No fasting. Antihistamines can usually be continued for a blood allergy test."
