# Rat Epithelium and Proteins

> This test measures the level of specific antibodies in your blood that react to proteins found in rat skin and hair. It helps show whether your immune system views these proteins as harmful, which is useful for investigating symptoms like sneezing or itching after contact with rats. This analysis helps distinguish a rat allergy from other environmental sensitivities. However, a positive result indicates sensitization and does not predict exactly how severe your physical reaction will be.
