Is Intradermal for tuberculosis testing

Yes, intradermal testing is commonly used for tuberculosis (TB) screening, specifically through the Mantoux test. In this procedure, a small amount of purified protein derivative (PPD) is injected just beneath the skin's surface, usually on the forearm. The test measures the immune response to the TB proteins after 48 to 72 hours, indicating whether a person has been exposed to the TB bacteria. A positive result usually requires further evaluation to confirm active TB.
