Tubersol Tuberculin Skin Tests

Tuberculin skin tests are primarily used to detect latent tuberculosis (TB) infections. By injecting a small amount of purified protein derivative (PPD) into the skin, healthcare providers assess the immune response, typically within 48 to 72 hours. A raised, hardened area at the test site may indicate TB exposure. It is commonly used in routine screenings for high-risk populations and helps in TB control efforts by identifying individuals who may need further evaluation or treatment.
