T-Spot TB
Order Code:
TSPOT
Test Summary
The T-Spot test is based upon a cell-mediated immune response in TB-infected individuals. The T cells of the patient are stimulated with Mycobacterium tuberculosis antigens. If the patient has previously been exposed to Mycobacterium tuberculosis, the exposure to these antigens in the T-Spot assay stimulate the patient's T cells to secrete the cytokine interferon-γ. The presence of the interferon-γ is then detected using an EIA method. According to the CDC, this assay may be used as a substitute for a TB skin test. It is more specific than the TB skin test, will detect latent TB, and a positive result is obtained in about 85% of the patients with active TB.
