Device Description
The Tosoh Automated Glycohemoglobin Analyzer HLC-723G8 (G8) is an automated High Performance Liquid Chromatography (HPLC) system that separates and reports stable Alc (sAlc) percentage in whole blood. The operational portion of the G8 is composed of a sampling unit, liquid pump, degasser, column, detector, microprocessors. sample loader, floppy disk drive unit, operation panel, and a printer.
The Tosoh Automated Glycohemoglobin Analyzer HLC-723G8 uses non-porous ionexchange high performance liquid chromatography (HPLC) for rapid, accurate and precise separation of the stable form of HbA1c from other hemoglobin fractions. The G8 uses a cation exchange column and separates the usual hemoglobin components in the blood into six fractions, Ala, A1b, F, L-A1c, sA1c, and A0. The separation is done by eluting the hemoglobins from the column with a stepwise elution of three elution buffers containing different salt concentrations. The result report is printed out and can be stored on a digital media. The result report includes a sample ID, date, percentage and retention time of each fraction. sA1c percentage and total A1 percentage (A1a+A1b+sA1c), along with a chromatogram of the elution pattern of the hemoglobin fractions. If a sample contains a hemoglobin variant, the column elutes the material depending upon its charge.
The calibrator set consists of two levels of calibrator, the low level in the non-diabetic range and the high level in the diabetic range. These two calibrators are used to establish a reference curve from which to establish the percentage of HbA1c in patient and control samples.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Tosoh Bioscience, Inc., has conducted substantial performance testing on the Automated Glycohemoglobin Analyzer HLC-723G8 and Hemoglobin A1c Calibrator Set, including interference testing, variant interference testing, method comparison testing with the predicate, dilution (total area/linearity), recovery/linearity testing, intra- and inter-assay precision testing, total precision/reproducibility testing, traceability, and analytic specificity testing. In addition, Tosoh Bioscience, Inc., compared the performance of the the Automated Glycohemoglobin Analyzer HLC-723G8 and Hemoglobin Alc Calibrator Set to its predicate device. A total of 114 specimens over a range of 4.0 to 16.8 % were compared. The difference between the two devices was within the allowable error range for all 114 of 114 specimens (100% ± 0.5). In all instances, the Automated Glycohemoglobin Analyzer HLC-723G8 and Hemoglobin A1c Calibrator Set functioned as intended and measurement of A1c and Total HbA was as expected.

Identification. A glycosylated hemoglobin assay is a device used to measure the glycosylated hemoglobins (A1a , A1b , and A1c ) in a patient's blood by a column chromatographic procedure. Measurement of glycosylated hemoglobin is used to assess the level of control of a patient's diabetes and to determine the proper insulin dosage for a patient. Elevated levels of glycosylated hemoglobin indicate uncontrolled diabetes in a patient.(b)

The Tosoh Automated Glycohemoglobin Analyzer HLC-723G8 is intended for IN VITRO DIAGNOSTIC USE for the measurement of hemoglobin A1c (HbA1c) in whole blood specimens. Hemoglobin A1c measurements are used in the clinical management of diabetes to assess the long-term efficacy of diabetic control.
The Hemoglobin A1c Calibrator Set is a reference agent designed for calibrating the Tosoh Automated Glycohemoglobin Analyzer HLC-723G8.
Technological Characteristics
The Tosoh Automated Glycohemoglobin Analyzer HLC-723G8 (G8) is an automated High Performance Liquid Chromatography (HPLC) system that separates and reports stable Alc (sAlc) percentage in whole blood. The operational portion of the G8 is composed of a sampling unit, liquid pump, degasser, column, detector, microprocessors. sample loader, floppy disk drive unit, operation panel, and a printer.
