Description

Tuberculin purified protein derivative (PPD) is used as a test to help diagnose tuberculous infection.

How the test is done: Tuberculin PPD is injected into the surface layers of the skin. If the test is positive, a reaction will be seen at and around the place of injection or puncture. If the test is given using an injection, this reaction is usually a hard, raised area with clear margins. If the test is given using the puncture devices, the reaction is usually a swollen area at the puncture site. Forty-eight to 72 hours after administration of the injection the size of the reaction is measured and recorded and the results of the test are studied.

Tuberculin PPD is to be used only by or under the supervision of a doctor.

Before Using
