Device Story

Stat Profile Prime ES Comp Plus Analyzer is a microprocessor-based, benchtop blood electrolyte analyzer for clinical laboratory use. It accepts lithium heparinized whole blood (syringes, open tubes, cups), serum, or plasma. Device utilizes ion-selective electrode (ISE) technology for pH, ionized calcium, and ionized magnesium, and impedance sensing for hematocrit. System features automated sampling, calibration, and quality management. User interface includes a 5.7" VGA touch screen, thermal printer, and integrated barcode scanner. Output provides quantitative analyte concentrations and calculated parameters (e.g., temperature-corrected pH, normalized calcium/magnesium). Healthcare professionals use results to diagnose and manage metabolic, renal, and acid-base conditions. Device benefits include rapid, automated point-of-care or lab-based testing to guide clinical decision-making.

Clinical Evidence

No clinical trials performed. Analytical performance established via bench testing: precision (within-run and run-to-run), linearity, interference, and method comparison against the predicate. Method comparison (N=150-191 whole blood, 100-121 plasma, 100-115 serum) showed high correlation (r² > 0.98) across all analytes. LoB, LoD, and LoQ determined per CLSI EP17-A2.

Technological Characteristics

Microprocessor-based analyzer; ion-selective electrodes (ISE) for iCa, iMg, pH; impedance sensor for Hct. Dimensions/form factor: benchtop analyzer with sensor card housing. Connectivity: barcode reader, onboard printer, QMS. Calibration: automated via sealed pouches. Sterilization: N/A (in vitro diagnostic).

Indications for Use

Indicated for use by healthcare professionals in clinical laboratories for quantitative measurement of pH, Hct, iCa, and iMg in heparinized venous whole blood, plasma, and serum to assist in diagnosing/treating parathyroid disease, bone disease, renal disease, tetany, magnesium imbalances, acid-base disturbances, anemia, and erythrocytosis. Not for point-of-care use.

Regulatory Classification

Identification
