Tuberculin
» Tuberculin conforms to the regulations of the FDA concerning biologics (650.10 to 650.15) (see Biologics 
1041
). It is a sterile solution derived from the concentrated, soluble products of growth of the tubercle bacillus (Mycobacterium tuberculosis or Mycobacterium bovis) prepared in a special medium. It is provided either as Old Tuberculin, a culture filtrate adjusted to the standard potency based on the U.S. Standard Tuberculin, Old, by addition of glycerin and isotonic sodium chloride solution, or as Purified Protein Derivative (PPD), a further purified protein fraction standardized with the U.S. Standard Tuberculin, Purified Protein Derivative. It has a potency, tested by comparison with the corresponding U.S. Standard Tuberculin, on intradermal injection of sensitized guinea pigs, of between 80 percent and 120 percent of that stated on the label. It is free from viable Mycobacteria as shown by injection into guinea pigs.
