A rapid sputum tests is used to diagnose tuberculosis (TB) when other tests show that a person probably has TB. Rapid sputum tests are also called nucleic acid amplification tests (NAATs). One of the best ways to diagnose TB is through a sputum culture.

If a person does not return within 48-72 hours for a tuberculin skin test reading, a second test can be placed as soon as possible. There is no contraindication to repeating the TST unless a previous TST was associated with a severe reaction.

When should I know the results of my TB (tuberculosis) test? It takes 48 to 72 hours (two to three days) to complete a skin TB test. Once you have your second visit with your healthcare provider, they'll be able to tell you if your skin's reaction indicates that you may or may not have a TB infection.

The two-step test is NOT the usual PPD skin test in which you receive an injection of PPD and the test area is observed one time at specific time frame. The two-step PPD test is used to detect individuals with past TB infection who now have diminished skin test reactivity.

There are 2 TB blood tests approved by the FDA. Quest is the only lab that offers both. Quest offers both the T-SPOT^®. TB and the QuantiFERON^®-TB Gold Plus (QFT-Plus) blood tests—with results available from a single visit that can be reported directly to an EHR.

The skin test reaction should be read between 48 and 72 hours after administration by a health care worker trained to read TB skin results. If a patient has symptoms of TB disease, health care providers should not wait for TB skin test results before starting other diagnostic tests.

It usually takes 2 to 10 weeks after exposure to a person with TB disease for the skin test to react positive. The test may also be falsely negative if the person's immune system is not working properly.

A “positive” TB blood test result means you probably have TB germs in your body. Most people with a positive TB blood test have latent TB infection. To be sure, your doctor will examine you and do a chest x-ray. You may need other tests to see if you have latent TB infection or active TB disease.

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. But the induration's size, not the color, will determine your results. An induration of less than 5 millimeters (mm) is a negative result.

Can I read my own TB skin test? ›

The tuberculin skin test must be given and read by a professional who has been trained to do this, and has been informed of the most recent guidelines in tuberculosis control. Never allow anyone other than a nurse or physician to read a tuberculin skin test.

Tuberculosis testing is not currently available with an at-home kit. Tests for both latent and active TB infections require careful administration and interpretation by a health professional in a medical setting.

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.

Rates of protection against tuberculosis infection vary widely and protection lasts up to 20 years. Among children, it prevents about 20% from getting infected and among those who do get infected, it protects half from developing disease. The vaccine is given by injection into the skin.

QFT has been shown to be more accurate than the TST in identifying people who may have latent TB infection.

If the first TB skin test result is negative, a second TB skin test should be done 1 to 3 weeks later. If the second TB skin test result is positive, it is probably a boosted reaction.

The test is "negative" if there is no bump (or only a very small bump) at the spot where the fluid was injected. A negative TB skin test usually means that you don't have TB.

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.
