Intended Use

A glucose test system is a device intended to measure glucose quantitatively in blood and other body fluids. Glucose measurements are used in the diagnosis and treatment of carbohydrate metabolism disorders including diabetes mellitus, neonatal hypoglycemia, and idiopathic hypoglycemia, and of pancreatic islet cell carcinoma.

Device Story

In vitro diagnostic assay for quantitative glucose measurement in human serum, plasma, urine, or CSF; utilizes hexokinase/G-6-PDH enzymatic methodology; hexokinase phosphorylates glucose in presence of ATP/magnesium to produce G-6-P; G-6-PDH oxidizes G-6-P to 6-phosphogluconate, reducing NAD to NADH; NADH production measured spectrophotometrically at 340 nm; used on AEROSET and ARCHITECT c8000 systems; operated by laboratory professionals; output provides quantitative glucose concentration; results assist clinicians in diagnosing/managing carbohydrate metabolism disorders.

Clinical Evidence

Bench testing only. Precision studies (CLSI EP5-A/EP10-A) performed on AEROSET and ARCHITECT systems; total %CV ranged from 0.80% to 2.15%. Linearity verified across 5-800 mg/dL (serum) and 1-800 mg/dL (urine/CSF). Interference testing confirmed acceptable recovery (±6% serum, ±10% urine) for common substances (bilirubin, hemoglobin, triglycerides, etc.). Method comparison (n=102 serum, 41 urine, 52 CSF) against predicate showed high correlation (r > 0.999).

Technological Characteristics

Liquid, ready-to-use single reagent kit. Contains NAD (5.0 mg/mL), G-6-PDH (3,000 U/L), Hexokinase (15,000 U/L), ATP 2Na (9.0 mg/mL). Sensing principle: spectrophotometric absorbance at 340 nm. Analyzers: Abbott AEROSET and ARCHITECT c8000. Calibration stability: 30 days. Shelf-life: 12 months.

Indications for Use

Indicated for quantitative measurement of glucose in human serum, plasma, urine, or cerebrospinal fluid (CSF) to aid in the diagnosis and treatment of carbohydrate metabolism disorders, including diabetes mellitus, neonatal hypoglycemia, idiopathic hypoglycemia, and pancreatic islet cell carcinoma.

### Test Description:

The Glucose assay is used for the quantitation of glucose in human serum, plasma, urine, or cerebrospinal fluid (CSF). Glucose is phosphorylated by hexokinase (HK) in the presence of adenosine triphosphate (ATP) and magnesium ions to produce glucose-6-phosphate (G-6-P) and adenosine diphosphate (ADP). Glucose-6-phosphate dehydrogenase (G-6-PDH) specifically oxidizes G-6-P to 6-phosphogluconate with the concurrent reduction of nicotinamide adenine dinucleotide (NAD) to nicotinamide adenine dinucleotide reduced (NADH). One micromole of NADH is produced for each micromole of glucose consumed. The NADH produced absorbs light at 340 nm and can be detected spectrophotometrically as an increased absorbance.

#### Performance Characteristics:

Comparative performance studies were conducted using the AEROSET® and ARCHITECT® c8000 Systems. The Glucose assay method comparison yielded acceptable correlation with the Glucose/HK assay on the Hitachi 917 Analyzer. The AEROSET System showed a correlation coefficient of 0.9995, slope of 1.09, and Y-intercept of - 5.50 mg/dL for the serum application, a correlation coefficient of 0.9998, slope of 1.09, and Y-intercept of - 1.35 mg/dL for the urine application, and a correlation coefficient of 0.9998, slope of 1.09, and Y-intercept of - 4.29 mg/dL for the CSF application when compared to the Hitachi 917 Analyzer. The ARCHITECT c8000 System showed a correlation coefficient of 0.9993, slope of 1.06, and Y-intercept of - 4.54 mg/dL for the serum application, a correlation coefficient of 0.9998, slope of 1.04, and Y-intercept of -- 2.67 mg/dL for the urine application, and a correlation coefficient of 0.9997, slope of 1.04, and Y-intercept of -3.89 mg/dL for the CSF application when compared to the Hitachi 917 Analyzer. The ARCHITECT c8000 System showed a correlation coefficient of 0.9996, slope of 0.97 and Y-intercept of 0.85 mg/dL for the serum application, a correlation coefficient of 0.9999, slope of 0.96, and Y-intercept of -1.36 mg/dL for the urine application, and a correlation coefficient of 0.9998. slope of 0.95, and Y-intercept of 0.22 mg/dL for the CSF application when compared to the AEROSET System. The Glucose assay method comparison yielded acceptable correlation between the AEROSET System and the ARCHITECT c8000 System.

Precision studies were conducted using the Glucose assay. On the AEROSET System, the total %CV for Level 1 is 1.06%, and Level 2 is 1.41% for the serum application, the total %CV for Level 1 is 1.66%, and Level 2 is 1.35% for the urine application, and the total %CV for Level 1 is 1.55%, and Level 2 is 1.69% for the CSF application. On the ARCHITECT c8000 System, the total %CV for Level 1 is 2.15%, and Level 2 is 1.51% for the serum application, the total %CV for Level 1 is 1.01%, and Level 2 is 0.80% for the urine application, and the total %CV for Level 1 is 1.07%, and Level 2 is 1.17% for the CSF application.

{3}------------------------------------------------

The Glucose assay is linear from 5 to 800 mg/dL for the serum/plasma application. The Glucose assay is linear from 1 to 800 mg/dL for the urine/CSF application. The limit of quantitation (sensitivity) of the Glucose assay is 5.0 mg/dL for the serum application, and 1.0 mg/dL for the urine/CSF applications.

These data demonstrate that the performance of the Glucose assay is substantially equivalent to the performance of the Glucose/HK assay on the Hitachi 917 Analyzer.

#### Conclusion:

The Glucose assay is substantially equivalent to the Glucose/HK assay on the Hitachi 917 Analyzer as demonstrated by results obtained in the studies.
