CSD skin test

CSD skin test
The CSD skin test determines whether or not a person has been infected with cat scratch disease. It is performed by injecting a CSD antigen under the skin with a needle. After 48 to 72 hours the site of injection is evaluated by a physician. If the test is positive the injection site will show evidence of a reaction.
