The Prodigy Preferred Blood Glucose Monitoring System is intended to be used for the quantitative measurement of glucose (sugar) in fresh capillary whole blood samples drawn from the fingertips, forearm, upper arm, palm, calf or thigh. The Prodigy Preferred Blood Glucose Monitoring System is intended to be used by a single person and should not be shared.
The Prodigy Preferred Blood Glucose Monitoring System is intended for self testing outside the body (in vitro diagnostic use) by people with diabetes at home as an aid to monitor the effectiveness of diabetes control. The Prodigy Preferred Blood Glucose Monitoring System should not be used for the diagnosis of or screening of diabetes or for neonatal use. Alternative site testing should be done only during steady - state times (when glucose is not changing rapidly).
The Prodigy No Coding Test Strips are for use with the Prodigy Preferred Blood Glucose Meter to quantitatively measure glucose (sugar) in fresh capillary whole blood samples drawn from the fingertips, forearm, upper arm, palm, calf or thigh.
The Prodigy Preferred Blood Glucose Monitoring System consists of a meter and Prodigy No Coding Test Strips. The system utilizes an electrochemical method-based meter and dry reagent biosensor (test strips) for blood glucose testing. The size of the current is proportional to the amount of glucose present in the sample, providing a quantitative measurement of glucose in fresh whole blood and control solutions.
The Prodigy Preferred Blood Glucose Monitoring System is marketed as a meter only with a carrying case, battery, Owner's Manual, Quick Reference Guide, Logbook, and Warranty Card. The Prodigy Preferred Blood Glucose Monitoring System is also marketed as a meter kit with a carrying case, battery, Owner's Manual, Quick Reference Guide, Logbook, and Warranty Card, Prodigy Lancing Device, Prodigy Lancets, Prodigy No Coding Test Strips, and Control Solution. The Prodigy No Coding Test Strips utilizes the active enzyme is Glucose Oxidase, derived from Aspergillus niger.

2. Sample Size Used for the Test Set and Data Provenance
The document does not explicitly state the sample sizes for the test set for each specific study. It frequently refers to "test results," "data," or "blood samples" without providing the precise number of participants or measurements.
- Provenance: Not explicitly stated, but the studies involve "fresh capillary whole blood samples" and "venous whole blood" in a medical device context, suggesting a clinical or laboratory setting. The approval is from the US FDA, implying testing relevant to US regulatory standards. It does not state whether the studies were retrospective or prospective.
3. Number of Experts Used to Establish Ground Truth and Qualifications
- The document mentions "glucose analyzer YSI2300" as the reference method for ground truth in several performance tests (Precision, Linearity, System Accuracy, Hematocrit, Temperature for Equipment, Humidity for Equipment, Robustness).
- The YSI 2300 STAT Plus Glucose & Lactate Analyzer is a laboratory-grade reference instrument. Thus, the ground truth is established by a highly accurate and precise analytical instrument, not by human experts. The qualifications of the operators of this instrument are not detailed, but it's implied that they are qualified laboratory personnel.
4. Adjudication Method for the Test Set
- No adjudication method by human experts is mentioned for the test set. The direct comparison is against a reference instrument (YSI2300).
5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study
- No multi-reader multi-case (MRMC) comparative effectiveness study is mentioned. The device is a blood glucose meter, which provides a direct numerical reading, not an interpretation like an imaging device that would typically involve human readers. Therefore, the concept of "human readers improve with AI vs without AI assistance" does not apply in this context.
6. Standalone (Algorithm Only Without Human-in-the-Loop Performance) Study
- Yes, the performance tests described (Precision, Linearity, System Accuracy, Interference, etc.) represent standalone performance of the device (meter + test strip system). The device provides a direct quantitative measurement, and these studies evaluate its accuracy and performance independently of human interpretation, although human users operate the device and apply the blood sample. The "Human Factor Study" addresses ease of use and label comprehension for the human operator, but the core performance metrics are device-centric.
7. Type of Ground Truth Used
- The primary ground truth used for analytical performance studies is comparison to a laboratory reference instrument, specifically the YSI 2300 STAT Plus Glucose & Lactate Analyzer. This is a highly accurate and precise method for determining blood glucose levels. For the Disinfection Efficacy, the ground truth was the efficacious removal of HBV as per FDA guidance.
8. Sample Size for the Training Set
- The document does not provide information on a "training set" sample size. This type of medical device (blood glucose meter) is typically developed through analytical validation of its electrochemical principles and biochemical components, rather than through machine learning model training on large datasets in the way an AI-driven diagnostic would be. The "design verification and validation testing" refers to broader engineering and performance validation rather than machine learning training.
9. How Ground Truth for the Training Set Was Established
- As no "training set" for a machine learning model is mentioned or implied, the method for establishing its ground truth is not applicable. The device's "training" in a broad engineering sense would involve iterative design, prototyping, and testing against known glucose concentrations and reference methods to optimize its performance characteristics.
