The Hemoglobin Variants System is intended as a qualitative screen for the presence of hemoglobins F, A, S, D, C and E in eluates of neonatal blood collected on filter paper by high-performance liquid chromatography (HPLC). The Hemoglobin Variants System is intended for Professional Use Only. For in vitro diagnostic use. The Hemoglobin Variants System is for use only with the Newborn Hemoglobin System (NHS). This device, consisting of the reagents, controls, apparatus, HPLC instrumentation, software is indicated for professional laboratory IVD use to isolate and identify inherently determined abnormal (S, D, C, E) and normal (F, A) hemoqlobin types in neonatal blood samples.

The instrument, Newborn Hemoglobin System (NHS) utilizes same principles of ionexchange high-performance liguid chromatography (HPLC). The NHS instrument is a fully automated, high-throughput hemoglobin analyzer. It utilizes principles of ion-exchange highperformance liquid chromatography (HPLC). The NHS provides an integrated method for the separation and determination of relative percent of specific hemoglobins of dried blood spots. The dried blood spot collected from neonatal heel stick is punched and eluted with deionized water. The punched disc is removed and eluted sample is transferred into microplate well. The eluted sample is analyzed to identify specific inherently abnormal (S, D, C, E) as well as normal (F, A) hemoglobins through the system. The NHS consists of two modules — the Newborn Chromatographic Station (NCS) and the Newborn Auto Sampler (NAS). NCS module delivers buffer solutions (See table 4 for kit components) to the Hemoglobin Variants System CE Mini-Columns and the detector. The NAS module through automatic injection introduces eluted sample from microplate wells. Each sample is processed individually. The mini-column contains a cation exchange gel, and the analyzer makes use of a continuous pre-programmed gradient system. The preprogrammed gradient is designed to have the hemoglobins of interest elute from the minicolumn with retention times that fall within pre-determined windows characteristic of known normal and abnormal hemoglobins. The ionic strength of two phosphate buffers passing through the mini-column is changed over three minutes. The eluted hemoglobins introduced through automatic injection are sequentially detected with a dual-wavelength filter photometer. which monitors hemoglobin absorbance at 415 nm and corrects for any gradient induced absorbance changes at 690 nm. Detection is performed at two wavelengths (415 nm and 690 nm) to ensure a stable baseline. Sample of water immediately following a newborn or quality control sample prevents carryover. A workstation is used to control the Newborn Hemoglobin System using Genetic Disease Management (GDM) software. The GDM software is designed to execute the assay protocol on the NHS instrument using the Hemoglobin Variants System reagent kit components. The software processed HPLC data is outputted in a printed report that contains: 1) sample identification, 2) date and time of analysis, 3) report data (i.e., peak names, retention times, area, relative percent), and 4) chromatogram. Also system assigns a presumptive phenotype "pattern" to each sample result. The pattern is calculated by applying a set of "rules" to the peaks identified in the peak table. The purpose of the pattern rules is to eliminate minor peaks from the pattern, identify system or sample problems, and to focus the operator on the samples that may require further investigation. The pattern rules used by the GDM software were derived from those generated by the Genetic Diseases Laboratory for the state of California, USA, after analysis of 2.5 million newborns by HPLC over a four year period (Eastman, et al., 1996)'. Laboratories using the Newborn Hemoglobin System pattern rules and assignment should perform an internal validation study to confirm the performance of the system for their application. 1.Eastman, J. W.; Wong, R.; Liao, C. L.; Morales, D. R. Automated HPLC Screening of Newborns for Sickle Cell Anemia and Other Hemoglobinopathies. Clin. Chem. 1996, 42 (5), 704—710. The HbReview Software is to support the review of transmitted result and release of an approved result for each neonate sample analyzed on Hemoglobin Variants System with Newborn Hemoglobin System. A screening site using Newborn Hemoglobin Systems (NHS) transmits results from the Genetic Disease Management (GDM) software to the central site. The central site uses HbReview software to review results, identify samples for retesting, add comments and release results to the reporting site. Features are provided to assist Reviewers and Approvers in their tasks of examining results from the Hemoglobin Newborn Screening test. The HbReview software is a Client-Server design. The Review process provides a user interface (client) to a relational database, which is located on a separate computer (the server). The Client software permits an authorized user to make changes to the data maintained on the Server.

The D-10™ Hemoglobin A1c Program is intended for professional in vitro diagnostic use only.

The D-10™ Hemoglobin Testing System utilizes the principles of ion-exchange highperformance liquid chromatography (HPLC). A dual-piston, low pulsation HPLC pump and a proportioning value deliver the buffer solution to an analytical cartridge and detector. Whole blood samples undergo an automatic two step dilution process and then introduced into the analytical flow path. Pre-diluted samples are aspirated directly and introduced into the analytical flow path. Between sample injections, the sample probe is rinsed with Wash/Diluent Solution to minimize sample carryover. 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 photometer flow cell where changes in the absorbance are measured at 415 nm and recorded as a digital chromatogram. The software performs a reduction of raw data collected from each analysis that may indicate use of a calibration factor. A samples report and chromatogram are generated for each sample. The D-10™ Hemoglobin A1c Program is designed to be used on the D-10™ Hemoglobin Testing System with or without a D-10 Rack Loader.

The Bio-Rad D-100™ HbA1c utilizes principles of ion-exchange high-performance liquid chromatography (HPLC). 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. Prediluted samples are identified based upon the use of a microvial adapter in the sample rack, and the automatic dilution step is omitted. 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 415 nm 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 are percent. Any peaks that are identified as the target analyte(s) are calibrated before generating a sample report and chromatogram for each sample. The software includes an optional feature (Advisor) that compares the sample report against a set of rules that are programmed to take user-specified actions. The D-100™ HbA1c test is designed to be used on the D-100™ Hemoglobin Testing System.
