What are the advantages of the T-Spot Test?

T-Spot Test for detection of TB is one of the newest tests. Other TB tests take more visits and a long-time procedure and still are not very accurate.

  • This is a single-visit blood test. In other words, it requires a single patient visit to conduct the test.
  • Results can be prepared within 24 hours.
  • If the person has already received the BCG vaccine, this test will not result in false-positive results. Therefore, the results of this test are not affected by previous vaccinations.

BCG, or bacille Calmette-Guerin, is effective against tuberculosis and is mainly used in countries where the prevalence of TB is high. The vaccine is not recommended in the US because the prevalence of Mycobacterium tuberculosis is not high in this country.

 

How to do the T-Spot Test?

In this test, a person’s immune reactivity against Mycobacterium tuberculosis is evaluated. White blood cells in people with TB produce interferon-gamma when it is mixed with antigens. Therefore, to perform this test, the blood sample is mixed with antigen, and the results are expressed as positive, negative, borderline, and invalid. The antigen is a part of a microorganism structure that triggers an immune response, mainly producing antibodies in the body.
