The Quo-Test A1C Analyzer and Reagent Test System (Quo-Test A1C System) are intended for the in-vitro quantitative determination of glycated hemoglobin in whole blood samples obtained from fingerstick or venous samples for point-of-care testing. The Quo-Test A1C System is indicated in the management and treatment of diabetes and for monitoring long term glycemic control by diabetics. It is for multiple patient use. Only auto-disabling, single use lancing devices should be used with this system.


Study Type: Observational
Official Title: Reproducibility and Method Comparison of the Quo-Test™ A1C System and the Quo-Lab A1C Test and CLIA Waiver of the Quo-Test™ A1C System

Further study details as provided by Quotient Diagnostics Limited:

Primary Outcome Measures:
  • The objective is to conduct reproducibility testing using duplicates of each of 3 levels of HbA1C [ Time Frame: 10 Days ]
    The objective is to conduct a method comparison between both the Quo-Test and Quo-Lab investigational devices and the reference method [Tosoh G8 (K071132)]. The reference method also serves as the predicate for the premarket notifications for both investigational devices. Both capillary and venous samples will be tested on the Quo-Test A1C System and Quo-Lab A1C Test, while only venous samples will be tested on the reference method.

Secondary Outcome Measures:
  • Obtain CLIA Waiver Status for the Quo-Test [ Time Frame: 10 Days ]

Biospecimen Retention:   Samples Without DNA
Whole Blood Venous Draw and Capillary Blood - IVD Study
