Tina-quant® HbA1c - Setting a new precedent in HbA1c lab efficiency


Diabetes mellitus, rainking 7th in the top ten global causes of death, has become a worldwide health topic.In 2017, 1 in every 11 adults was diagnosed with diabetes (425 million) with approximately 50% of adults have undiagnosed diabetes.2

HbA1c, which reflects the average glucose level in the last 8-12 weeks, is one of the most widely used test in diabetes management. Current ADA guidelines recommend the HbA1c tests for use in diagnosing type 2 diabetes and prediabetes.2,3 Therefore, it is critical for the lab to use a standardized assay with good quality to support the right clinical decision.

On cobas® series platforms, the Tina-quant® HbA1c assay empowers the laboratory to reduce TAT, optimize operational cost with various solutions, and build confidence on the results for clinical decisions.

The Tina-quant® HbA1c assay aims to meet all of your needs in HbA1c measurement for routine diabetes management. Each and every time!

Testing Throughput for Lab TAT

  • The Tina-quant® HbA1c assay is available on the platforms with different throughput, eg. cobas INTEGRA 400 plus, cobas c 111, 311, 501/502, 503
  • Dedicated high throughput close tube sampling HbA1c system: cobas c 513 (400 samples/hour)



Workflow Efficiency for Operational Cost


  • Roche digital diagnostics
  • Robustness in cobas® Series with long MTBRV4 time
  • Ready-to-use cassette
  • Direct result reporting (no result validation needed)
  • No sample preparation5



Results Accuracy for Clinical Decision


  • IFCC (traceable to IFCC ref. method) certified
  • NGSP (traceable to DCCT study) certified
  • FDA clearance with diagnostics claim6
  • Result report in duel units: mmol/mol (SI) and % (DCCT)
  • Highly specific antibody, no interference of common variants (HbS, C, D, E)7
  • Excellent CV, eg. cobas c 513 < 1% in DCCT unit5
  • Good correlation to different methodology standardized8
