What are PPD Tests?

A PPD (purified protein derivative) test, also known as the Mantoux tuberculin skin test, is a diagnostic procedure employed to detect a past or present tuberculosis (TB) infection. The test identifies an individual’s reaction to a substance derived from the bacteria causing TB. A positive result indicates that the person has been exposed to the bacteria, but it doesn’t necessarily mean they have active TB.

The PPD Testing Procedure

PPD tests are a simple skin test. A healthcare professional will inject a small amount of PPD tuberculin into the inner surface of your forearm. The injected site forms a slight bump, which subsides shortly. After 48-72 hours, you’ll need to return to the healthcare provider to have the test area evaluated. If there’s a raised lump with a specific size or larger at the injection site, the result is often considered positive. The size threshold can vary based on certain factors, such as the individual’s health status and the prevalence of TB in the community.

Why is it Important?

Tuberculosis remains a significant global health threat, and early detection is crucial for treatment and controlling its spread. If left untreated, TB can be fatal. Identifying an infection, even if it is latent (inactive), is vital for starting appropriate treatment and preventing potential transmission. A PPD test is especially crucial for those who are at a higher risk of TB exposure, such as healthcare workers or individuals who have recently traveled to areas with a high prevalence of the disease.
