Tuberculin Purified Protein Derivative
(Mantoux) Diagnostic Antigen (Aid in the detection of infection with Mycobacterium tuberculosis)
FOR INTRADERMAL USE
Polysorbate 80 Stabilized Solution of Tuberculin Purified Protein Derivative for Tuberculin Testing in Humans
TUBERSOL®, Tuberculin Purified Protein Derivative (Mantoux) (PPD) (1) for intradermal tuberculin testing is prepared from a large Master Batch Connaught Tuberculin (CT68) (2) and is a cell-free purified protein fraction obtained from a human strain of Mycobacterium tuberculosis grown on a protein-free synthetic medium and inactivated. (2) The use of a standard preparation derived from a single batch (CT68) has been adopted in order to eliminate batch to batch variation by the same manufacturer. (2)
TUBERSOL is a clear, colorless liquid.
|Purified protein derivative of M. tuberculosis||5 TU per 0.1 mL|
|Phenol||0.22% to 0.35% w/v|
in sterile isotonic phosphate buffered saline.
Before release, each successive lot is tested for potency in comparison with the US Standard Tuberculin PPD-S. (3)
Independent studies conducted by the US Public Health Service in humans have determined the amount of CT68 in stabilized solution necessary (4) (5) (6) to produce bio-equivalency with Tuberculin PPD-S (in phosphate buffer without polysorbate 80) using 5 US units (TU) Tuberculin PPD-S as the standard.
