The summary describes a standard blood gas analyzer and does not mention any AI/ML capabilities, image processing, or training/test sets typically associated with such technologies.
No.
The device is described as a system used to analyze whole blood samples to aid in diagnosis, not to provide therapy.
Yes
The "Intended Use / Indications for Use" section explicitly states that the parameters measured by the device "aid in the diagnosis of a patient's acid/base status, oxygen delivery capacity, and electrolyte and metabolite balance."
No
The device description explicitly states it is a "portable system" and an "instrument" that provides "quantitative measurements of whole blood samples," indicating it is a hardware device with analytical capabilities, not solely software.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use explicitly states that the device is used to "rapidly analyze whole blood samples" and that the results "aid in the diagnosis of a patient's acid/base status, oxygen delivery capacity, and electrolyte and metabolite balance." Analyzing samples in vitro (outside the body) to aid in diagnosis is the core definition of an IVD.
- Sample Type: The device analyzes "whole blood samples," which are biological specimens taken from the body.
- Parameters Measured: The parameters measured (pH, pCO2, pO2, Na+, K+, Ca++, Hct, Base Excess, HCO3, TCO2, sO2) are all clinically relevant markers used in the diagnosis and monitoring of various medical conditions.
- Clinical Setting: The device is intended for use "at the point of health care delivery in a clinical setting," which is a typical environment for IVD use.
The information provided clearly aligns with the definition of an In Vitro Diagnostic device.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Precision: Blood gas precision data were generated by using three levels of controls (GEM Check Plus) for pH, pCO2, pO3, Na+, K+, Ca++ and two levels of controls (GEM critCheck) for hematocrit. Control levels were run in replicates of 4 once a day for 14 days (twice on Day 1) for a total of 60 replicates on each of 7 different IL GEM 3000 instruments (total n=420). The table shows the combined within run and total %CV of the seven instruments.
Method Comparison: The method comparison data included arterial, venous, heart bypass and liver transplant blood samples from hospital patients using heparinized syringes and from healthy volunteers using heparinized vacutainer tubes. All samples were analyzed on the GEM Premier 3000 using an IL Synthesis as the predicate device with the exception of the hematocrit parameter, which used manual spun hematocrit as the predicate device. The GEM Premier 3000 was shown to be statistically similar to the predicate devices for the parameters listed. Sample sizes for method comparison ranged from 80 to 130 depending on the parameter.

Dear Ms. Marble:
We have reviewed your Section 510(k) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.
If your device is classified (see above) into either class II (Special Controls) or class III (Premarket Approval), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 895. A substantially equivalent determination assumes compliance with the Current Good Manufacturing Practice requirements, as set forth in the Quality System Regulation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic QS inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations.
