Intended Use

The GEM Premier 7000 with iQM₃ is a portable critical care system for use by health care professionals to rapidly analyze lithium heparinized whole blood samples at the point of health care delivery in a clinical setting and in a central laboratory. The instrument provides quantitative measurements of pH, pCO2, pO2, sodium, potassium, chloride, ionized calcium, glucose, lactate, hematocrit, total bilirubin, and CO-Oximetry (tHb, O2Hb, COHb, MetHb, HHb, sO2*) parameters from arterial, venous, or capillary lithium heparinized whole blood. These parameters, along with derived parameters, aid in the diagnosis of a patient's acid/base status, electrolyte and metabolite balance and oxygen delivery capacity.

Device Story

Portable critical care system; analyzes lithium heparinized whole blood samples (arterial, venous, capillary) at point-of-care or central lab. Uses potentiometry, amperometry, electrical conductivity, and spectrophotometry to measure pH, blood gases, electrolytes, metabolites, hematocrit, bilirubin, and CO-Oximetry parameters. Includes iQM₃ (Intelligent Quality Management) with new photometric hemolysis detection feature. Device flags samples with hemolysis ≥116 mg/dL plasma-free hemoglobin to prevent reporting of inaccurate potassium results. Healthcare providers use output to diagnose acid-base disturbances, electrolyte imbalances, and oxygen delivery capacity. Benefits include rapid, accurate bedside testing and automated detection of pre-analytical sample interference.

Clinical Evidence

Bench testing only. Verification studies included internal method comparison, internal whole blood precision, hemolysis interference on potassium, hemolysis verification, shelf-life, and use-life studies. Testing followed CLSI guidelines (EP05-A3, EP07, EP09c, EP25-A, EP37). Results demonstrated that the addition of the hemolysis detection module does not impact performance and that the device is equivalent to the predicate.

Technological Characteristics

Portable critical care analyzer. Measurement principles: potentiometry (pH, pCO2, Na+, K+, Cl-, Ca++), amperometry (pO2, glucose, lactate), electrical conductivity (hematocrit), and spectrophotometry (bilirubin, CO-Oximetry). Features iQM₃ for automated quality management and photometric hemolysis detection. Operates on lithium heparinized whole blood. Connectivity and software architecture are consistent with the predicate GEM Premier 5000.

Indications for Use

Indicated for health care professionals to analyze lithium heparinized whole blood (arterial, venous, capillary) for pH, blood gases, electrolytes, metabolites, hematocrit, total bilirubin, and CO-Oximetry parameters to aid in diagnosis/treatment of acid-base, electrolyte, metabolite, and oxygenation status in clinical/laboratory settings.

#### Device Description

#### The GEM Premier 7000 with iQM3

The GEM Premier 7000 with iQMs system provides health care professionals with quantitative measurements of lithium heparinized whole blood pH, pCO2, pO2, Na*, K*, Ch, Ca**, glucose, lactate, Hct, total bilirubin and CO-Oximetry (tHb, O2Hb, COHb, MetHb, HHb, sO₂*) from arterial, venous or capillary samples at the point of health care delivery in a clinical setting and in a central laboratory.

*sO₂ = Ratio between the concentration of oxyhemoglobin plus deoxyhemoglobin plus deoxyhemoglobin.

| Key Components | Description |
|------------------------------------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| Instrument | It employs a unique touch-sensitive color screen and a simple set of menus<br>and buttons for user interaction. The analyzer guides operators through<br>the sampling process with simple, clear messages and prompts. |
| PAK (Cartridge) | All required components for sample analysis are contained in the GEM PAK,<br>including sensors, optical cell for CO-Oximetry and total bilirubin, sampler,<br>pump tubing, distribution valve, waste container and Process Control<br>Solutions. The GEM PAK is an entirely closed analytical system. The operator<br>cannot introduce changes to the analytical process before or during the<br>GEM PAK's use-life on board the instrument. |
| | The GEM PAK has flexible menus and test volume options to assist facilities<br>in maximizing efficiency. The EEPROM on the GEM PAK includes all solution<br>values and controls the analyte menu and number of tests. |
| | The setup of the instrument consists of inserting the GEM PAK into the<br>instrument. The instrument will perform an automated GEM PAK start-up<br>during which the following is performed: warm-up (15 minutes), sensor<br>conditioning (10 minutes), Process Control Solution (PCS) performance (15<br>minutes), all of which take about 40 minutes. |
| | After GEM PAK start-up, Auto PAK Validation (APV) process is automatically<br>completed: two completely independent solutions traceable to NIST<br>standards, CLSI procedures or internal standards, containing two levels of<br>concentration for each analyte (PC Solution D and E), are run by the analyzer<br>to validate the integrity of the PC Solutions and the overall performance of<br>the analytical system.<br>Note: GEM PAKs that include tBili analyte will require the successful<br>performance of CVP 5 tBili. |
| | Includes all necessary components for hemolysis detection, such as an<br>acoustofluidic flow cell, an LED light source and an optical detector, for<br>appropriate flagging of potassium measurements in whole blood samples<br>without additional sample volume or sample processing steps. |
| Intelligent Quality Management<br>(iQM3) | iQM3 is used as the quality control and assessment system for the GEM<br>Premier 7000 system. iQM3 is an active quality process control program<br>designed to provide continuous monitoring of the analytical process<br>before, during and after sample measurement with real-time, automatic<br>error detection, automatic correction of the system and automatic<br>documentation of all corrective actions, replacing the use of traditional<br>external QC. |
| | iQM3 introduces hemolysis detection in whole blood samples, enhancing<br>quality assessment in the pre-analytical phase of testing. |
