What is purified protein derivative PPD?
Tuberculin Purified Protein Derivative (PPD) is a sterile aqueous solution of a purified protein fraction for intradermal administration as an aid in the diagnosis of tuberculosis.
What does purified protein derivative contain?
PPD-S was comprised of approximately 92.9% protein, 5.9% polysaccharide, and 1.2% nucleic acid (Seibert & Glen, 1941). Because of its enhanced purity and potency, PPD-S was adopted as the international standard of tuberculin by the World Health Organization (WHO) in 1952 (Guld, et al., 1958).
What is tuberculin purified protein derivative made of?

What is the amount of purified protein derivative PPD injection?
The TST is performed by injecting 0.1 ml of tuberculin purified protein derivative (PPD) into the inner surface of the forearm. The injection should be made with a tuberculin syringe, with the needle bevel facing upward. The TST is an intradermal injection.
How is a PPD test given?
The standard recommended tuberculin test, known as the Mantoux test, is administered by injecting a 0.1 mL of a liquid containing 5 TU (tuberculin units) of PPD into the top layers of skin (intradermally, immediately under the surface of the skin) of the forearm.
What is the role of purified protein derivative PPD in the diagnosis of TB?
When TB infects your body, it becomes extra sensitive to certain elements of the bacteria, such as the purified protein derivative. A PPD test checks your body’s current sensitivity. This will tell doctors whether or not you have TB.

What is a purified protein derivative skin test?
A purified protein derivative (PPD) skin test is a test that determines if you have tuberculosis (TB). TB is a serious infection, usually of the lungs, caused by the bacteria Mycobacterium tuberculosis. This bacteria spreads when you breathe in the air exhaled by a person infected with TB. The bacteria can remain inactive in your body for years.
