With the T-SPOT.TB test a blood specimen is collected using routine phlebotomy and a standard blood collection tube, this is then transported at room .T-SPOT.TB counts the number of antimycobacterial effector T cells, white blood cells that produce interferon-gamma, in a sample of blood.This gives an overall measurement of the host immune response against mycobacteria, which can reveal the presence of infection with Mycobacterium tuberculosis, the causative agent of tuberculosis (TB). Because this does not .T Cells Matter 1. When your test looks for signs of TB infection using T cells, it matters how many T cells you include. The T-SPOT.TB test, unlike other tests, uses the same number each time. And it’s a big number: 250,000 cells per well, four wells per test. That’s a million witnesses to infection – and a moment of truth for TB. TECHNOLOGY
The T-SPOT ®. TB test is an in vitro diagnostic test for the detection of effector T cells that respond to stimulation by Mycobacterium tuberculosis antigens ESAT-6 and CFP 10 by capturing interferon gamma (IFN- γ) in the vicinity of T cells in human whole blood collected in sodium citrate or sodium or lithium heparin. 1 It is intended for use as an aid in the diagnosis of M .

Mycobacterium tuberculosis is the bacteria responsible for the infectious disease known as tuberculosis (TB). It spreads easily from person to person, mainly . An alternative to the tuberculin skin test (TST) e.g. Mantoux test has emerged in the form of a new type of in-vitro T-cell-based assay: the interferon-gamma assay. interferon-gamma assays are based on the principle that T cells of individuals sensitised with tuberculosis antigens produce interferon gamma when they re-encounter mycobacterial antigensWhen your test looks for signs of TB infection using T cells, it matters how many T cells you include. The T-SPOT.TB test, unlike other tests, uses the same number each time. And it’s a big number: 250,000 cells per well, four wells per test. 1 That’s a million witnesses to infection – and a moment of truth for TB. The principles of the T .
Blood samples to be processed with the T-SPOT.TB test must be used within 8 hours post venepuncture. Samples can be used up to 32 hours post venepuncture with the addition of the T-Cell Xtend reagent prior to running the T-SPOT.TB test. Whole blood samples should be maintained between 18°C and 25°C until pro-cessed.

It is intended for use as an aid in the diagnosis of M.tuberculosis infection.Interferon-gamma release assay (IGRA) test. This is a blood test based on detecting the response of white blood cells to TB antigens. It is less likely to give false positive results compared with a Mantoux test and gives a rapid result.

The T-SPOT.TB test is an in vitro diagnostic test for the detection of effector T cells that have been specifically activated by MTB antigens and is intended for use as an aid in the diagnosis of MTB infection. The T-SPOT. T-SPOT TB Test . T-SPOT TB test is also a single visit, blood test. This is the only blood test cleared by the FDA for patients as young as 2 years old. Enzyme-linked immunospot (ELISPOT) methodology is used by the T-SPOT TB test to similarly count the T cells that have been sensitized by TB infection, as described above.
