The description of "Intelligent Quality Management 2 (iQM2)" mentions "Pattern Recognition" as one of its checks. While "Pattern Recognition" can be a component of AI/ML, the description does not provide enough detail to definitively confirm the use of AI/ML algorithms. It could be a simpler statistical pattern detection method.
No
This device is an in vitro diagnostic (IVD) device used for diagnostic purposes by measuring various parameters in blood samples to aid in the diagnosis and treatment of diseases. It does not provide any therapeutic function.
Yes
Explanation: The "Intended Use / Indications for Use" section explicitly states that the measurements provided by the device "aid in the diagnosis of electrolyte balance." It further specifies that sodium, potassium, and chloride measurements "are used in the diagnosis and treatment" of various diseases involving electrolyte imbalance, and ionized calcium measurements "are used in the diagnosis and treatment" of parathyroid disease, bone diseases, renal disease, and tetany.
No
The device description clearly outlines hardware components including an "Analyzer" with a touch screen, a "GEM Premier 5000 PAK" which houses sensors, optical cells, solutions, and other physical components, and mentions the analysis of whole blood samples, which requires physical interaction with the device. While it includes software (iQM2), it is an integral part of a larger hardware system.
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 heparinized whole blood samples" and provides "quantitative measurements" of various analytes (sodium, potassium, chloride, ionized calcium). These measurements "aid in the diagnosis of electrolyte balance" and are used in the "diagnosis and treatment of disease conditions." This aligns directly with the definition of an in vitro diagnostic device, which is intended for use in the collection, preparation, and examination of specimens taken from the human body for the purpose of providing information for the diagnosis, prevention, or treatment of a disease or condition.
- Sample Type: The device analyzes "heparinized whole blood samples," which are specimens taken from the human body.
- Analytes: The device measures specific analytes (electrolytes) in these samples.
- Purpose: The measurements are used to "aid in the diagnosis" and "monitor electrolyte balance in the diagnosis and treatment of disease conditions."
The description of the quality control materials (GEM System Evaluator, GEM Hematocrit Evaluator, GEM CVP 5 tBili) also reinforces that this is an IVD system, as quality control materials are essential components of IVD testing.

Device Description
The GEM Premier 5000 system provides health care professionals in central laboratory or point-of-care clinical settings with fast, accurate, quantitative measurements of sodium and ionized calcium from venous, arterial and capillary heparinized whole blood, as well as quantitative measurements of potassium and chloride from venous and arterial heparinized whole blood.
Key Components:
Analyzer: Employs a unique color touch screen and a simple set of menus and buttons for user interaction. The analyzer guides operators through the sampling process with simple, clear messages and prompts.
GEM Premier 5000 PAK (disposable, multi-use GEM PAK): Houses all required components necessary to operate the instrument once the cartridge is validated. These components include the sensors, CO-Ox/tBili optical cell, Process Control (PC) Solutions, sampler, pump tubing, distribution valve and waste bag. The GEM PAK has flexible menus and test volume options to assist facilities in maximizing efficiency. NOTE: The EEPROM on the GEM PAK includes all solution values and controls the analyte menu and number of tests. Step 1: After inserting the GEM PAK, the instrument will perform an automated PAK warm-up during which the sensors are hydrated and a variety of checks occur, all of which take about 40 minutes. During warm-up, the instrument requires no user intervention. Step 2: After GEM PAK warmup, Auto PAK Validation (APV) process is automatically completed: two completely independent solutions (PC Solution D and E) that are traceable to NIST standards, CLSI procedures or internal standards, containing two levels of concentration for each analyte, are run by the analyzer to validate the integrity of the PC Solutions and the overall performance of the analytical system. NOTE: For total bilirubin, CVP 5 tBili (Calibration Valuation Product) must be run prior to performing tBili samples. Step 3: After successful performance of APV, iQM2 manages the quality control process, replacing external quality controls.
Intelligent Quality Management 2 (iQM2): iQM2 is an active quality process control program designed to provide continuous monitoring of the analytical process before, during and after sample measurement with real-time, automatic error detection, automatic correction of the system and automatic documentation of all corrective actions. iQM2 is a statistical process control system that performs 5 types of continuous, quality checks to monitor the performance of the GEM PAK, sensors, CO-Ox, and reagents. These checks include System, Sensor, IntraSpect, Pattern Recognition and Stability Checks.

| PC Solutions | PC Solution B is the primary Process Control Solution measured at a minimum of every half hour or after every sample. Furthermore, Solution B is monitored every 30 seconds while residing in the sensor card between measurements. Further, PC Solution B is used as a reference blank for CO-Oximetry. PC Solution A is measured at a minimum of every 4 hours. All sensor slope values are also measured and checked. Slope, which is an indicator of sensor sensitivity and drift, must be within allowable limits. PC Solution A also contains dyes that are used for checking functionality of the optical cell and the CO-Oximetry. PC Solution C is measured at a minimum of once every 24 hours. PC Solution C is primarily used for measuring low-level oxygen; however, PC Solution C is also used to provide an additional measurement of pH, pCO2 and K+ sensor functionality. PC Solution D is measured every 12 hours. PC Solution D provides additional measurement for all analytes including CO-Oximetry.

External Precision - Whole Blood
To evaluate whole blood precision on the GEM Premier 5000 system in the central laboratory and point-ofcare (POC) settings, whole blood patient samples were tested at 2 external central laboratories and 1 internal Customer Simulation Laboratory (CSL), as well as at 3 external POC locations. For the central laboratory setting, the studies were performed by 3 operators on 3 GEM Premier 5000 instruments using a single lot of GEM Premier 5000 PAK (cartridge). For the POC setting, the studies were performed by 11 operators on 3 GEM Premier 5000 instruments, using a single lot of GEM Premier 5000 PAK (cartridge). At least two whole blood specimens were analyzed in triplicate daily for 5 days in both normal mode (150 µL) for all 4 electrolytes, and micro capillary (65 µL) mode for Nat and Ca**. At the internal Customer Simulation Laboratory (CSL), contrived whole blood specimens were analyzed in addition to native specimens in order to cover the low and high medical decision levels of each analyte.

Linearity
In accordance with CLSI EP06-A, nine (9) or ten (10) levels per analyte were prepared by spiking or diluting whole blood to challenge the claimed reportable range for each parameter. Each blood level was analyzed in triplicate on three (3) GEM Premier 5000 test analyzers and results compared to reference analyzers.
Combined data from limit of quantitation (LOQ) and linearity were used to support the lower limits of the claimed reportable ranges.

Total Error was computed based on the following equation and the results were compared to the GEM Premier 5000 Total Error Specifications:
Total Error Observed = Bias + 2 * SD (or %CV)

Clinical Testing
In accordance with EPO9-A3, a method comparison study was conducted on the GEM Premier 5000 compared to the predicate device, the GEM Premier 4000, in the point-of-care (POC) setting using heparinized whole blood patient samples from the intended use population.
- Study Design:
- . Three (3) external point-of-care (POC) sites.
- One (1) internal Customer Simulation Laboratory (CSL) at IL, where three (3) intended POC users were brought on site to run the samples, allowing spiking to cover the reportable ranges.
The pooled results from the POC sites and the IL internal Customer Simulation Laboratory (CSL) for the Normal Mode (with samples collected in syringes) are presented below.
