Rat Skin Extract: What to Know About This Allergy Test

Published: July 26, 2026Updated: August 31, 2026

Rat Skin Extract is an allergen extract used by trained healthcare professionals to help diagnose an immediate allergy to rats. It is generally given through skin-prick or intradermal testing and is not intended to treat allergy symptoms or be used at home. Your doctor or pharmacist can confirm how the specific product should be used.

Quick summary

Rat Skin Extract is mainly used for allergy testing, not for treating a rat allergy. It should be administered and interpreted by a healthcare professional because testing can cause allergic reactions.
