Description
The PPD 1 Step test is a standard screening procedure used to detect exposure to tuberculosis (TB). This test involves a single intradermal injection of purified protein derivative (PPD) and is a crucial step in identifying potential TB infection.
During the PPD 1 Step test, a small amount of PPD is injected just beneath the skin’s surface. After 48 to 72 hours, you will need to return for a reading of the test site to determine if there is a reaction, indicating possible TB exposure.
This test is commonly required for employment, school, or healthcare settings to ensure that individuals do not have active TB or are at risk of spreading it. It is a reliable and straightforward method for TB screening and essential for maintaining public health and safety.
