Device Story

System uses electronic biosensor test strips and handheld meter to measure blood glucose; capillary action draws 0.3 microliters of whole blood into strip chamber; glucose dehydrogenase enzyme reacts with glucose to produce electrical current; meter measures current to calculate glucose level; results displayed in ~15 seconds. Used in home and clinical settings by patients and healthcare professionals. Tracker system integrates with PDA for data management, analysis, and evaluation of historical results. Benefits include effective diabetes management through monitoring and historical data review.

Clinical Evidence

Clinical study compared palm and fingertip glucose values during conditions of rapid glucose change. Results demonstrated equivalence between sites, supporting the recommendation of the palm as an alternative test site.

Technological Characteristics

Electrochemical coulometric sensor; glucose dehydrogenase enzyme; capillary fill (0.3 microliters); result range 20-500 mg/dL; operating temp 50-95°F; humidity 5-90%; battery-powered (AAA or rechargeable PDA battery); data management via Tracker software; plasma equivalent calibration.

Indications for Use

Indicated for quantitative whole blood glucose measurement in patients with diabetes mellitus; for use by healthcare professionals and patients at home. Not for neonates, diagnosis, or screening. Tracker system indicated for use on finger, forearm, upper arm, thigh, calf, and hand.

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.

#### 3. Device Description

The FreeStyle Blood Glucose Monitoring System comprises an electrochemical biosensor glucose reagent test strip, a handheld meter, a quality control solution, a complete Owner's Booklet and Quick Reference Guide. A lancing device, lancets and a logbook for recording test results are also included with the system.

When the user inserts a test strip, the meter turns on. The user acquires a blood sample (with the test strip in the meter) by picking up the meter and touching the edge of the test strip at the blood target area, filling the chamber on the strip by capillary action. The meter sounds a tone (bee) to let the user know that the sample chamber is full and the reaction has begun. When the test is complete, the meter displays the glucose reading on its liguid crystal display (LCD).

# FreeStyle Blood Glucose Monitoring System

The TheraSense, Inc., FreeStyle Blood Glucose Monitoring System is intended for use in the quantitative measurement of glucose in whole blood. It is intended for use by healthcare professionals and people with diabetes mellitus at home as an aid in monitoring the effectiveness of diabetes control program. It is not intended for the diagnosis of or screening for diabetes mellitus, and is not intended for use on neonates.

# FreeStyle Tracker Diabetes Management System

The TheraSense, Inc., FrecStyle Tracker Diabetes Management System is intended for use in the quantitative measurement of glucose in whole blood. It is intended for use by healthcare professionals and people with diabetes mellitus at home as an aid in monitoring the effectiveness of diabetes control program. It is not intended for the diagnosis of or screening for diabetes mellitus, and is not intended for use on neonates.

Additionally, the TheraSense, Inc. FreeStyle Tracker Diabetes Management System is intended for use in home and clinical setting to aid people with diabetes and healthcare professionals in the review, analysis, and evaluation of historical blood glucose test results to support an effective diabetes management program.

The TheraSense, Inc. FreeStyle Tracker Diabetes Management System is specifically indicated for use on the finger, forearm, upper arm, thigh, calf and hand.

#### Principle of Operation న్.

The user obtains a blood sample using a conventional lancing technique on the finger or arm. The user inserts a test strip into the meter, which turns the meter on. When the strip is touched to the blood drop, the sample chamber on the strip tills by capillary action in approximately 2 seconds. The blood sample volume required is approximately 0.3 microliters (300 nanoliters), which can be obtained from the finger or other areas of the body such as the arm. Test results are displayed in about 15 seconds. The time required to

display test results varies depending on the blood glucose concentration (approximately 15 to 45 seconds).

The glucose in the blood sample reacts with the glucose Dehydrogenase enzyme to yield gluconolactone, and produces a small electrical current. This current is measured by the FreeStyle meter and displayed as a glucose level.

#### 6. Conclusion Drawn from Clinical Test Demonstrating Substantial Equivalence

The clinical study data demonstrate that during times of rapid glucose change, palm and fingertip glucose values are the same. This study confirms results in several published reports which show the equivalence of fingertip and palm glucose test results under conditions of rapid glucose change. The combination of TheraSense's confirmatory study and published support TheraSense's proposed labeling change to recommend the palm of the hand as an alternative test site even under conditions of rapidly changing blood glucose.
