Automating the T-SPOT.TB test

In TB testing, why trade accuracy for efficiency when you don’t have to?

The T-SPOT®.TB test is now automated using the T-Cell SelectTM reagent kit which provides a simplified workflow while maintaining the same superior clinical performance you can expect from the T-SPOT.TB test. 1,2

The T-SPOT.TB test with the T-Cell Select reagent kit provides you with:

  • Superior clinical performance 1,2
  • Reduced hands-on time
  • Extended blood sample stability
  • Improved blood sample logistics
  • Maximized operational efficiency
  • Customizable and scalable solutions

What is T-Cell Select?
T-Cell Select is a peripheral blood mononuclear cell isolation reagent that uses positive selection of targeted immune cells with magnetic bead-based cell separation to automate and simplify the preparation of cells for the T-SPOT.TB test.

Simplified workflow using magnetic bead-based cell separation to quickly isolate targeted immune cells

Reduces hands-on time

Automation of the T-SPOT.TB test has been shown to reduce hands-on time as much as 50% in European laboratories, depending on what components of the modular system are used.

Reduce hands-on time as much as 50%
Increase sample throughput without increasing the number of technicians
Free up technicians for other laboratory tasks

Allows for scalability

By choosing to automate just one, a number, or all of the processes within the T-SPOT.TB test workflow, you can select the most cost-effective solution for your specific needs.

Low throughput automation

Uncompromising accuracy for immunocompromised patients

Automation of the T-SPOT.TB test makes the clinically superior IGRA1,2 accessible to more physicians who treat vulnerable immunocompromised patients.

Patient and nurse
  1. Maintains superior clinical performance

    The step the T-Cell Select reagent kit automates plays a key role in maintaining the clinical performance of the T-SPOT.TB test even in challenging to diagnose populations like the immunocompromised3

  2. Displays superior sensitivity

    The ATS/IDSA/CDC guidelines state that the T-SPOT.TB test displays superior sensitivity (90 – 95 %) to the TST (71 – 81 %) and the QFT®-GIT test (81 – 86 %)2
