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

Diabetes mellitus, ranking 9th in the top ten global cuases of deaths, has become a worldwide health topic.1 In 2019, more than one in 10 adults is living with diabetes (537 million) with approximately 45% of adults having 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.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!
