The document describes a standard electrochemical blood glucose monitoring system and does not mention any AI or ML components.
No
The device is used for the quantitative measurement of glucose, aiding in monitoring the effectiveness of diabetes control. It is for "in vitro diagnostic use" and explicitly states it "should not be used for the diagnosis of, or screening for diabetes." These characteristics indicate it is a diagnostic or monitoring device, not a therapeutic device which would directly treat a condition.
No
The text explicitly states: "The Prodigy® AutoCode® Eject Blood Glucose Monitoring System should not be used for the diagnosis of, or screening for diabetes, or for neonatal use." While it measures glucose, its intended use is for monitoring effectiveness of diabetes control rather than initial diagnosis.
No
The device description explicitly states that the system consists of a meter and test strips, which are hardware components. It also mentions a lancing device and lancets as part of a kit.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Explicit Statement: The "Intended Use / Indications for Use" section clearly states: "The Prodigy® AutoCode® Eject Blood Glucose Monitoring System is intended for self-testing outside the body (in vitro diagnostic use)..." and "They are for testing outside the body (in vitro diagnostic use only)".
- Definition of IVD: An IVD is a medical device used to examine specimens, such as blood, taken from the human body to provide information for diagnosis, monitoring, or screening. This device fits this definition by measuring glucose in blood samples.
- Purpose: The system is intended to measure glucose in blood samples to aid in monitoring the effectiveness of diabetes control, which is a diagnostic and monitoring purpose.

Intended Use / Indications for Use
Prodigy® AutoCode® Eject 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® AutoCode® Eject Blood Glucose Monitoring System is intended to be used by a single person and should not be shared. The Prodigy® AutoCode® Eject 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® AutoCode® Eject Blood Glucose Monitoring System should not be used for the diagnosis of, or screening for diabetes, or for neonatal use. The alternative site testing should be done only during steady-state times (when glucose is not changing rapidly).
PRODIGY® No Coding Test Strips are intended for use with the PRODIGY® AutoCode® Eject blood glucose meter to measure the concentration of the blood glucose in fresh capillary whole blood samples drawn from the fingertips, forearm, upper arm, palm, calf or thigh for self-testing at home. They are for testing outside the body (in vitro diagnostic use only) . Do not use them for diagnosis of, or screening for dabetes or for testing on neonates. PRODIGY® No Coding Test Strips are used as an aid to monitor the effectiveness of diabetes control.

Device Description
The Prodigy® AutoCode® Eject 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® AutoCode® Eject Blood Glucose Monitoring System is marketed as a meter only with a carrying case, batteries, Owner's Manual, Quick Reference Guide, Logbook, and Warranty Card.
The Prodigy® AutoCode® Eject Blood Glucose Monitoring System is also marketed as a meter kit with a carrying case, batteries, Owner's Manual, Quick Reference Guide, Logbook, and Warranty Card, Prodigy Lancing Device, Prodigy Lancets, Prodigy No Coding Test Strips, and Control Solution.

● Substantial Equivalence (SE) Discussion
A claim of substantial equivalence is made to PRODIGY Preferred® Blood Glucose Monitoring System (K122338). Both of them have the same indications for use, the same working principle and technologies including using the same Prodigy No-Coding test strips and PRODIGY Control Solution, sample volume, operating & storage conditions, HCT range, detecting range.
The major differences for the two devices are measuring time, meter dimensions, meter weight; power battery, memory storage, and speaking feature The speaking function for the subject device is indicated not to be used by visually impaired person, just an aid for all of the users. The subject device and predicate device are intended for use in the quantitative measurement of glucose in fresh capillary whole blood from the finger and the following alternative sites: the palm, the forearm, the upper-arm, the calf and the thigh. Thus the differences are due to the feature design aspects, not related to the safety or effectiveness aspects. They are substantially equivalent.
● Synopsis of Test Methods and Results
Pre-clinical and clinical data are employed upon submission of this 510(K) premarket notification according to the Guidance Document for In Vitro Diagnostic Test System; Guidance for Industry and FDA document provided by CDRH/ FDA.
● Conclusion
The conclusions drawn from the non-clinical tests demonstrate that the device is as safe, as effective, and performs as well as the legally marketed device identified in the submission. Thus the subject device is substantially equivalent to the predicate devices.
