What Does PPD Stand For?
PPD stands for Purified Protein Derivative
PPD, or Purified Protein Derivative, is a sterile extract derived from the culture of Mycobacterium tuberculosis. It is primarily used in medical diagnostics, particularly the tuberculin skin test, to determine an individual's exposure to tuberculosis infection. PPD stimulates an immune response, allowing healthcare professionals to assess whether further evaluation or treatment for tuberculosis is necessary.
