PPD skin test 

The Mantoux tuberculin skin test (TST) is the standard method of determining whether a person is infected with Mycobacterium tuberculosis. Reliable administration and reading of the TST requires standardization of procedures, training, supervision, and practice.

How i s the TST Administered?

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. When placed correctly, the injection should produce a pale elevation of the skin (a wheal) 6 to 10 mm in diameter.

How i s the TST Read?

The skin test reaction should be read between 48 and 72 hours after administration.

A positive result will form a red and swollen circle at the site of the injection. The size (diameter) of the swollen raised circle determines whether exposure to TB has occurred. The size that is considered positive varies with the health status and age of the individual. Even when infected, children, the elderly, and people who are severely immune compromised (such as those with AIDS) may have smaller, delayed, or even negative reactions to the TST.

 

Is there anything else I should know?

Positive TST results are commonly seen in those who have received a BCG (Bacille Calmette-Guérin) vaccination. IGRA results are not affected by BCG.

A negative TST may cause mild itching or discomfort at the injection site. A person may not respond to a TB skin test (even with TB exposure) if the person has had a recent viral infection, a "live" vaccine (such as measles, mumps, chickenpox, influenza), or has overwhelming tuberculosis, another bacterial infection, or is taking immune suppressive drugs such as corticosteroids.

A person should generally wait 4-6 weeks to do a TB skin test after having had a vaccination with a live-virus vaccine.

Kinda pricey

Even with my student discount the price for a TB test was 1.5x higher than if I just went to the walk-in clinic.

Easy and Affordable

Shopping for my lab tests was simple and quick. I thought that I would end up spending more than I did.
