Evaluation of the Quo-Test hemoglobin A1c point-of-care instrument: second chance.

摘要

We previously reported the evaluation of 8 different hemoglobin A_(1c) (Hb A_(1c): point-of-care instruments (1). Two of 8 manufacturers withdrew from that study after initial unpromising results. One of the 2 instruments withdrawn was the Quo-Test Alc (Quotient Diagnostics), which was withdrawn because of a technical problem. The manufacturer claimed to have resolved the problem and asked us to reevaluate the instrument.The Quo-Test method is based on affinity separation and the use of fluorescence quenching and gives results in 3 min. The instrument was certified by the National Gycohemoglobin Standardization Program (NGSP) as of September 2009 (2 ).
