The T-SPOT.TB test technology

1 small tube. 1 million ways to find the truth.1
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. It’s intended for use as an aid in the diagnosis of tuberculosis (TB) infection. The T-SPOT.TB test is a simplified enzyme-linked immunospot (ELISPOT) method which enumerates individual TB-specific activated effector T cells.

T-Cell Xtend
The T-Cell Xtend reagent allows blood samples to be processed up to 32 hours after venipuncture without affecting the accuracy of the test. With the T-Cell Xtend reagent, the T-SPOT.TB test offers IGRA users unrivalled flexibility.

T-Cell Select
The new T-Cell Select reagent kit allows automated sample preparation and enables the T-SPOT.TB test to be used with blood samples stored for up to 54 hours at room temperature.
The T-Cell Select reagent uses a magnetic bead-based system to isolate the cells using positive selection. This provides exceptional cell purity without negatively impacting T cell function or the superior clinical performance of the T-SPOT.TB test.
T-SPOT.Discovery
The T-SPOT Discovery SARS-CoV-2 kit has been developed to aid in the investigation of the T cell response to SARS-CoV-2 infection. The kit uses a modified ELISPOT assay where samples prepared from peripheral blood are stimulated in vitro by peptide pools from SARS-CoV-2. This re-stimulation allows SARS-CoV-2 specific T cells to be enumerated.
The T-SPOT Discovery SARS-CoV-2 kit is for research use only. Not for use in diagnostic procedures.
