In 2 to 3 days, the client returns to the Health Department to get their test results. If the skin test or blood test is positive the client will be given additional tests, such as a chest x-ray, to determine if he or she has latent TB infection or TB disease. 2. How much does a Tuberculosis (TB) test cost?

After the test, you should avoid using bandages, putting on lotion, or scratching the test area because it may affect the results. You can wash the area with water, but do not wipe or scrub. If the area itches, put an ice cube or cold cloth on it.

The skin test reaction should be read between 48 and 72 hours after administration by a health care worker trained to read TST results. A patient who does not return within 72 hours will need to be rescheduled for another skin test. The reaction should be measured in millimeters of the induration (firm swelling).

Tuberculin Skin Test (TST) is a screening method developed to evaluate an individual's status for active Tuberculosis (TB) or Latent TB infection. A 2-Step TST is recommended for initial skin testing of adults who will be periodically retested, such as healthcare workers.

In this procedure a person is given a baseline PPD test. If the test is negative, a second test is administered one to three weeks later. If the second test is negative, the person is considered uninfected.

If you have an Mtb infection, the skin around the injection site should start to swell and harden within 48 to 72 hours . This bump, or induration, may also change color.

What does a positive TB test look like after 72 hours? ›

Within 48 to 72 hours, a positive TB skin test is marked by an area of reddish induration greater than 10 mm. It is the induration (firm bump) that is gently palpated that determines the size, not the area of redness. This reaction is slightly larger than the average positive test 17 mm in size.

The authors state that, in adults, the size of the Mantoux reaction for tuberculin testing is significantly larger at 72 hours than at 48 hours. They add that in clinical practice, tuberculin tests should be read at 72 hours to reduce the number of false-negative results.

Results. Redness alone at the skin test site usually means you haven't been infected with TB bacteria. A firm red bump may mean you have been infected with TB bacteria at some time. The size of the firm bump (not the red area) is measured 2 to 3 days after the test to find out the result.

What is a one-step TB skin test? A one-step TB test requires that you come in for the test, and return 48-72 hours later to have it read. If you arrive more than 72 hours later the test cannot be read, as the result is no longer valid.

The Labcorp OnDemand QuantiFERON™ Tuberculosis Blood Test can help find out if you have ever been exposed to TB bacteria or if you need evidence of a negative TB test. Note: This screening test is not intended to be used to diagnose a latent TB infection or active TB disease.
