The world’s leading IGRA – now with powerful, flexible automation solutions

QuantiFERON-TB Gold Plus

The world’s leading IGRA – now partnered with the world’s leading automation solutions

TB remains one of the most contagious and deadly infectious diseases in the world today. Every case of TB begins with a “silent” latent TB infection. If latent TB is detected early enough, it can be treated and cured before it becomes active disease. Eliminating the vast reservoir of latent TB infection is the key to stopping TB once and for all.

The WHO recommends systematic latent TB testing with tests like QuantiFERON-TB Gold Plus for populations at increased risk, including anyone living with HIV infection, contacts of active pulmonary TB cases and patients receiving TNF-a inhibitor therapy. The QuantiFERON TB test is one of only two TB blood tests that has received endorsement from the WHO.

QuantiFERON-TB Gold Plus – it’s time to test and treat latent TB

QIAGEN and QuantiFERON-TB Gold Plus are proud to be your partner of choice and your test of choice in the global fight to end TB.

QuantiFERON-TB Gold Plus (QFT-Plus) is an objective laboratory test that is more accurate than the century-old tuberculin skin test. Unlike the TB skin test, QFT-Plus testing is unaffected by prior BCG-vaccination, and results are available with only a single patient visit.

Know your TB status – and gain true peace of mind – by choosing QFT-Plus.

LIAISON QuantiFERON-TB Gold Plus Test

In the face of increasing consolidation and workload, labs are looking for automation solutions that can help control test costs and improve efficiency. QIAGEN and DiaSorin have now partnered to help accelerate conversion of the global latent TB testing market to modern blood-based QuantiFERON technology.

DiaSorin is proud to offer the LIAISON QuantiFERON-TB Gold Plus Test – the first and only chemiluminescence-based (CLIA) detection solution in the European market. Performing the QFT-Plus test on DiaSorin LIAISON family platforms provides an automated, flexible workflow with complete traceability and easy integration into current lab routines. With the DiaSorin LIAISON family of automated analyzers, labs can embed QFT-Plus in broad menu of assays on a best-in-class clinical diagnostic platform:

  • Testing on demand with Random Access technology
  • Reduced hands-on time with improved time to first result and overall test turnaround
  • Check-in, barcode duplication, automatic interpretation of results, repetitions and retesting with LIAISON QuantiFERON software (LQS)
  • Integrated testing on a single automation platform

Continuous workflow optimization for confidence in your test results

QFT-Plus has the most flexible blood collection options on the market including single tube collection. To further improve the efficiency of single tube blood collection, aliquoting of blood from single tubes into  QFT-Plus tubes will be streamlined on the Tecan Fluent Laboratory Automation workstation or the Hamilton Microlab STAR automated liquid handling workstation. These instruments can automate aliquoting to support a more efficient single tube sample collection workflow. These optimized single tube workflows will provide:

  • Ease of use and improved patient experience at the blood collection site
  • Aliquoting of blood from single tube into QFT-Plus tubes for better control of blood volume prior to incubation
  • Automated liquid handling for efficient upstream sample processing in large volumes
  • Streamlined sample processing with reduced hands-on time
