GLUCOMETER ENCORE Blood Glucose Test Strips are for the self-monitoring of blood glucose as an adjunct to the care of persons with diabetes*
GLUCOMETER ENCORE Blood Glucose Test Strips are over-the-counter home tests for glucose in blood. They are for use by persons with diabetes and by healthcare professionals in home settings and in healthcare facilities. GLUCOMETER ENCORE Blood Glucose Test Strips are for use with GLUCOMETER ENCORE® Blood Glucose Meters.
Here's an analysis of the provided text, focusing on acceptance criteria and study details:
1. Table of Acceptance Criteria and Reported Device Performance
The provided text does not explicitly state specific numerical acceptance criteria for the GLUCOMETER ENCORE® Blood Glucose Test Strips. Instead, it describes a comparative study showing the device "compared well" and is "equivalent in performance" to predicate devices and other laboratory methods.
| Acceptance Criteria (Explicitly Stated) | Reported Device Performance |
|---|---|
| Not explicitly stated | Compared well to predicate and other laboratory methods. |
| Not explicitly stated | Equivalent in performance to the predicate device. |
| Quantitative measurement range 10-600 mg/dL (0.6-33.3 mmol/L) | Device is capable of this range. |
2. Sample Size Used for the Test Set and Data Provenance
- Sample Size: Not explicitly stated. The text mentions "Fresh arterial specimens collected from catheters and deep sticks were used," implying multiple samples, but no specific number is provided.
- Data Provenance:
- Country of Origin: U.S. (from "STAT Laboratories of a large U.S. medical center").
- Retrospective or Prospective: Prospective, as it states "Fresh arterial specimens collected..."
3. Number of Experts Used to Establish Ground Truth for the Test Set and Their Qualifications
Not applicable. This device is a quantitative measurement device for blood glucose. The "ground truth" is established by reference laboratory methods, not by human expert opinion or interpretation.
4. Adjudication Method for the Test Set
Not applicable, as the ground truth is established by reference laboratory methods rather than human interpretation requiring adjudication.
5. If a Multi Reader Multi Case (MRMC) Comparative Effectiveness Study Was Done, and Effect Size
No, an MRMC study was not done. This type of study is typically for image interpretation or diagnostic tasks where human readers are involved. This study compares a device's quantitative output to reference methods.
6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done
Yes, this was a standalone performance study. The GLUCOMETER ENCORE systems (test strips with meters) were evaluated by themselves, with their results compared directly to other methods. There is no indication of a human-in-the-loop component for interpreting the device's output in the context of the performance assessment.
7. The Type of Ground Truth Used
The ground truth was established by "other laboratory methods for the determination of glucose" and comparison to the "Accu-Chek® Advantage™ H Blood Glucose Meter" (predicate device). This indicates that a gold standard or highly accurate laboratory reference method was used.
8. The Sample Size for the Training Set
Not applicable. The text describes a performance evaluation of a device, not a machine learning model that undergoes training.
9. How the Ground Truth for the Training Set Was Established
Not applicable, as there is no training set for a machine learning model.
