# Rat Serum

> This test measures the level of specific antibodies in your blood that react to proteins found in rat serum. It helps show whether your immune system is sensitive to rats, which is useful if you experience sneezing, itching, or breathing issues after exposure to these animals. The results help distinguish a specific allergy to rats from other environmental triggers. However, this test cannot predict the severity of an allergic reaction or diagnose other respiratory conditions on its own.
