Notes:
A PPD skin test is used to determine if someone has been exposed to the TB bacteria. During testing, a Purified Protein Derivative (PPD) is injected just under the skin. The site of injection is examined 48 to 72 hours later. If there is a reaction, the site is measured. At Shands, a reading of mm based on the induration (swelling or lump) is considered positive. Immunosuppressed individuals must be evaluated using other criteria and are often considered to be positive at 5mm of induration.
Annual PPD testing/screening is required as part of your annual performance evaluation. When your skin test is completed, you will receive documentation from Occupational Health.
