Intended Use

The ASCENSIA™ DEX®2 Diabetes Care System is for the Self-Monitoring of Blood Glucose as an adjunct to the care of person with diabetes. 4

Device Story

The ASCENSIA™ DEX®2 Diabetes Care System is a blood glucose meter used by patients and healthcare professionals in home or clinical settings. It utilizes electrochemical amperometric glucose oxidase technology to measure glucose levels in whole blood samples. The system uses test sensor discs, which are individually sealed in packages of ten. The meter processes the electrochemical signal from the test strip to provide a quantitative blood glucose result, which is referenced to plasma glucose. The device provides a linear response for glucose concentrations ranging from 10-600 mg/dL. Healthcare providers use these results to monitor blood glucose levels, which serves as an adjunct to the management of diabetes. The system is designed for over-the-counter (OTC) use.

Clinical Evidence

In-house and clinical evaluations were conducted by healthcare professionals and persons with diabetes. Studies demonstrated that users obtain blood glucose results substantially equivalent to current blood glucose monitoring methods. No specific sensitivity, specificity, or p-values were provided in the summary.

Technological Characteristics

Amperometric glucose oxidase method; electrochemical sensing; linear range 10-600 mg/dL; results referenced to plasma glucose; test sensor discs packaged in sets of ten.

Indications for Use

Indicated for persons with diabetes and healthcare professionals in home and clinical settings for the measurement of glucose in whole blood as an adjunct to diabetes care.

Regulatory Classification

Identification

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.

Special Controls

*Classification.* Class II (special controls). The device, when it is solely intended for use as a drink to test glucose tolerance, is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 862.9.

# Device Description

The ASCENSIA™ DEX®2 Diabetes Care System consists of an electrochemical method-based meter and dry reagent sensor (test strips) designed for testing glucose by persons with diabetes or by healthcare professionals in the home or in healthcare facilities.

{1}------------------------------------------------

#### Statement of Intended Use:

The ASCENSIA™ DEX®2 Diabetes Care System is for the Self-Monitoring of Blood Glucose as an adjunct to the care of person with diabetes. 4

#### Summary of Technological Characteristics:

The ASCENSIA™ DEX®2 Diabetes Care System employs an amperometric glucose oxidase method to measure glucose in blood. It is conceptually the same as other blood glucose monitoring products available for blood glucose testing. The test sensor discs are individually sealed in a package of ten. Blood glucose results are referenced to plasma glucose. The System has a linear response to glucose from 10-600 mg/dL.

# Performance Data:

An evaluation of the ASCENSIA™ DEX® 2 Diabetes Care System was studied in-house and in clinical settings by healthcare professionals and by persons with diabetes. The studies demonstrated that users can obtain blood glucose results that are substantially equivalent to current methods for blood glucose.

# Conclusion:

The results of in-house and clinical evaluations of the ASCENSIA™ DEX® 2 Diabetes Care System demonstrate that the device is equivalent in performance to the predicate devices and suitable of its intended use.

Dear Mr. Tancos:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.
