TB Skin Test (PPD)

The TB Skin Test (PPD) is a two-visit protocol used to determine if you’ve been exposed to tuberculosis. It is commonly required for healthcare workers or individuals who may have been in close contact with someone with TB. This test helps detect early-stage infections, allowing for early treatment to prevent the spread of the disease. Results are typically read 48 to 72 hours after the initial injection. A positive result may require additional testing, such as a chest X-ray.
