The description focuses on electrochemical biosensor technology and embedded software for converting electrical current to glucose readings. There is no mention of AI or ML.
No
This device is an in-vitro diagnostic device used for measuring glucose levels, it is not a therapeutic device. It provides information but does not actively treat or prevent a condition.
Yes
The device is intended for the quantitative measurement of glucose, which provides information to monitor a condition (diabetes), fitting the definition of a diagnostic device. However, the text explicitly states it is "not intended for use... in the diagnosis of or screening for diabetes mellitus," implying it's for monitoring rather than initial diagnosis. Yet, the document also says it's for "in vitro diagnostic use," which overrides the previous statement for the purpose of this question.
No
The device description explicitly states that the system consists of a physical meter, test strips, control solutions, and a lancing device, in addition to embedded software. This indicates it is a hardware-based system with software components, not a software-only medical device.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Explicit Statement: The "Device Description" section explicitly states: "The microdot® Xtra Blood Glucose Monitoring System is intended for invitro diagnostic use..."
- Intended Use: The "Intended Use / Indications for Use" clearly describes the system's purpose as "self testing of glucose in capillary whole blood" and "quantitative measurement of glucose in fresh capillary whole blood." These are tests performed on samples taken from the body, which is the definition of in vitro diagnostics.
- Components: The system includes components like test strips and control solutions, which are typical for IVD devices used for chemical analysis of biological samples.

The microdot® Xtra Blood Glucose Monitoring System is intended for invitro diagnostic use and for the quantitative measurement of glucose in fresh capillary whole blood. The modified device ie microdor® Xtra Blood Glucose Monitoring System, and its predicate device, microdot® Blood Glucose Monitoring System are intended for use by persons with diabetes or by healthcare professionals in home settings or healthcare facilities.
The modified microdot® Xtra Blood Glucose Monitoring System is substantially equivalent in form, firmware, fundamental scientific technology and specifications as the predicate system. The microdot® Xtra Blood Glucose Monitoring System relies on quantitative electrochemical biosensor technology to measure current generated on disposable test strips.
The strip remains unchanged since the last submission approval, microdot® Blood Glucose Monitoring System (K070524). The Test Strip manufacturing and performance characteristics are unchanged. The test strips are designed to quantitatively measure glucose in fresh capillary blood from the fingertip by persons with diabetes or by healthcare professional in home or healthcare facilities. Both the predicate strips, microdor® Test Strips (K070524) and the microdot® Xtra Test Strips use the reagent qlucose dehydrogenase with nicotinamide-adenine dinucleotide as co-factor.
The predicate meter uses lot specific calibration code number marked on the strip vial label. The specific code number on the strip vial label allows the meter to convert electrical current into glucose readings via the embedded software in the meter. The user calibrates their meter each time they open a new vial of strips.
Each lot of strips is calibrated to give plasma equivalent glucose readings. The meter is turned on by strip insertion, the user applies a drop of blood or control solution to the test strip and the meter starts the measurement. After 10 seconds, the meter displays the glucose concentration and time and date on the LCD display.
The microdot® Xtra Blood Glucose Monitoring System is pre-programmed with a predetermined code number, thus removing the requirement to load a code number specific to the strip vial.
