T-SPOT®.TB

T-SPOT®.TB

The T-SPOT®.TB test is a blood test to detect tuberculosis infection (TI) that is performed in one visit to a specialist.

Description

Belongs to the IGRA family of tests for interferon gamma release assay (Interferon gamma release assay), which uses the unique ELISpot technology developed by Oxford Immunotech to ensure maximum accuracy of results in various patient groups.

T-SPOT.TB is highly informative in diagnosing TI with a specificity of 98.8% and a sensitivity above 99%[1]. T-SPOT.TB does not give false results in BCG-vaccinated individuals.

T-SPOT.TB is less susceptible to immunosuppression than other TB tests[2,3].

Therefore, this test is preferable for screening people living with HIV infection, as well as for screening for TI in patients before starting biological therapy.

IGRA tests are the standard for identifying latent TI in risk groups and are included in clinical guidelines in more than 30 countries, including the List of Essential In Vitro Diagnostic Tools of the World Health Organization[4].
