The Medconn Glycated Hemoglobin Test System is intended for the quantitative determination of hemoglobin A1c (IFCC mmol/mol and NGSP %) in human venous blood or hemolysate using ion-exchange high performance liquid chromatography (HPLC) on the Medconn Glycated Hemoglobin analyzer, models MQ-3000 and MQ-3000PT. A high-pressure pumping system delivers a buffer solution to an analytical cartridge and detector. Whole blood samples undergo an automatic hemolysis and dilution process before being introduced into the analytical flow path. Manually hemolyzed and prediluted samples loaded in sample cups at designated location are directly introduced for analysis. A programmed buffer gradient of increasing ionic strength delivers the sample to the analytical cartridge where the hemoglobin species are separated based upon their ionic interactions with the cartridge material and the buffer gradient. The separated hemoglobin species then pass through the flow cell where changes in the absorbance are measured at 415nm and recorded as a digital chromatogram. The software performs an analysis of the hemoglobin peaks in the chromatogram, recording information including retention time, peak area, and relative peak area of the detected substance over the total peak area of all substances. Peaks identified as target analytes are calibrated to generate a report and a chromatogram for each sample. Medconn Glycated Hemoglobin Test system contains the following components: - Medconn Glycated Hemoglobin analyzer - Medconn HbA1c Assay Kit (HPLC) - Medconn Hemoglobin A1c Calibrator - Medconn Hemoglobin A1c Control - Medconn HbA1c Column Kit (HPLC) - Medconn HbA1c Haemolyser

This test is an aid in diagnosis of diabetes and identifying patients who may be at risk for developing diabetes, and for monitoring of long-term blood glucose control in individuals with diabetes mellitus.

The Tosoh Automated Glycohemoglobin Analyzer HLC-723G8 is an automated High-Performance Liguid Chromatography (HPLC) system that separates and reports stable hemoglobin A1c (sA1c) percentage in venous whole blood. The operational portion of the G8 is composed of a sampling unit, liquid pump, degasser, column, detector, microprocessors, sample loader, smart media card, operation panel, and a printer. The Tosoh Automated Glycohemoglobin Analyzer HLC-723G8 uses ion-exchange HPLC for rapid, accurate, and precise separation of the stable form of HbA1c (sA1c) from other hemoglobin fractions. The G8 uses a non-porous cation exchange column and separates the hemoglobin components in the blood. Separation is achieved by utilizing differences in ionic interactions between the cation and exchange group on the column resin surface and the hemoglobin components in a step gradient elution. The hemoglobin fractions (designated as A1a. A1b. F. LA1c+, SA1c, A0, and, if present, H-V0, H-V2, H-V2 and H-V3) are subsequently removed from the column by performing a step-wise elution gradient using the varied salt concentrations in the Variant Elution Buffers HSi 1, 2 and 3. The peaks, H-V0, H-V1, H-V2 and H-V3 are typically presumptive HbAD, HbAS, HbAC and HbAE respectively. The software compares the retention times of hemoglobin fractions in a sample to the expected "windows of retention" and labels each fraction that correctly elutes within a defined expected window of retention. The software designates a hemoglobin fraction as POX (where X is the order of the peak as it elutes from the column) if it does not match a defined window of retention. All automated processes in the G8 are controlled by internal microprocessors, using software downloaded via a smart media card. The result report is printed and can be stored on the instrument. The data can be transmitted to a host computer through a bi-directional interface. The result report includes the sample ID, date, percentage and retention time of each fraction of hemoglobin, sA1c percentage and total A1 percentage, along with a chromatogram of the elution pattern of the hemoglobin fractions. If a sample contains a hemoglobin variant, the column elutes the fraction depending upon its charge.

Tina-quant Hemoglobin A1cDx Gen.3 assay is an in vitro diagnostics reagent system intended for quantitative determination of mmol/mol hemoglobin A1c (IFCC) and % hemoglobin A1c (DCCT/NGSP) in hemolysate or whole blood on the cobas c 503 clinical chemistry analyzer. The assay offers separate applications that are specific to the sample types whole blood and hemolysate. The Whole Blood Application differs from the Hemolysate Application in the hemolyzing step. For the Whole Blood Application, whole blood samples are placed on the analyzer and hemolysis occurs onboard the analyzer. For the Hemolysate Application, hemolyzed samples are placed on the analyzer and hemolysis occurs manually before placing the samples onboard the analyzer. The two applications yield the same results. Hemolyzing reagent is part of the test system and is either placed on board the analyzer for the Whole Blood Application or used manually for the Hemolysate Application. Anticoagulated whole blood is hemolyzed either manually or automatically prior to determination of HbAlc by a turbidimetric inhibition immunoassay. Liberated hemoglobin (Hb) in the hemolyzed sample is converted to a derivative having a characteristic absorption spectrum and measured bichromatically. The instrument calculates the % HbAlc from the HbAlc/Hb ratio according to a user selected protocol, either IFCC or NGSP protocols.

The HbA 1c (Hemoglobin A 1c) Advanced assay on the Beckman Coulter DxC700 AU Clinical Chemistry Analyzer, is intended for the quantitative determination of mmol/mol HbA1c (DCCT/NGSP) concentration in human venous whole blood.

The HbA1c calibrator is supplied with the reagent, in a liquid, ready to use format and contains 5 x 2mL calibrator levels. The sample hemolysis is automated on the DxC700 AU Clinical Chemistry analyzer. Sample handling is performed as follows: 200 uL of hemolyzing reagent is aspirated from the Hemolyzing Reagent R1and dispensed into a cuvette. Tetradecyltrimethylammonium bromide (TTAB) in the hemolyzing reagent eliminates interference from leukocytes. 2 µL of whole blood sample is then aspirated from the patient sample and added to the hemolyzing reagent in the cuvette. This hemolyzed whole blood is then added to the THb assay cuvette and HbA1c assay cuvette as per the assay parameters. The concentrations of both HbA1c and Total Hemoglobin are determined. The HbA1c/Total Hemoglobin ratio is expressed either as mmol/mol (IFCC) or %HbA1c (DCCT/NGSP). Total Hemoglobin Reagent is used to measure total hemoglobin concentration by a colorimetric method. Change in absorbance is measured at 570/660 nm. HbA1c reagent is used to measure hemoglobin A1c concentration by a turbidimetric immunoinhibition method. In the reaction, hemoglobin A1c antibodies combine with HbA1c from the sample to form soluble antigen-antibody complexes. Polyhaptens from the reagent then bind with the excess antibodies and the resulting agglutinated complex is measured turbidimetrically. Change in absorbance is measured at 340/700 nm.

The Afinion™ HbA1c Dx is a fully automated boronate affinity assay for the determination of the percentage of hemoglobin A1c in human whole blood. The Afinion™ HbA1c Dx is a modification of the existing device, Alere Afinion™ HbA1c for use with the Alere Afinion™ AS100 Analyzer, with the addition of a diagnostic intended use. The test begins with a blood sample collected with the integrated sampling device before the test cartridge is placed in the cartridge chamber of the Alere Afinion™ AS100 Analyzer. The sample is then automatically diluted and mixed with a solution that releases hemoglobin from the erythrocytes. After the hemoglobin is precipitated, the sample mixture is transferred to a blue boronic acid conjugate which binds to the cis-diols of glycated hemoglobin. This reaction mixture is soaked through a filter membrane and all precipitated hemoglobin, conjugate-bound and unbound (i.e. glycated and non-glycated hemoglobin) remains on the membrane. Excess conjugate is removed with a washing reagent. The analyzer measures the reflectance of the precipitate on the membrane as blue (glycated hemoglobin) and red (total hemoglobin) color intensities. The analyzer calculates a ratio proportional to the percentage of HbA1c in the sample and displays as the % HbA1c (NGSP).
