The Abbott i-STAT EG7+ cartridge is a comprehensive, single-use disposable diagnostic tool designed for rapid point-of-care blood testing in critical care, emergency, and surgical environments. Its primary purpose is to simultaneously measure a broad panel of critical physiological parameters from a single small sample of whole blood, including arterial blood gases, pH, electrolytes like sodium and potassium, ionized calcium, glucose, and hematocrit. By delivering laboratory-accurate quantitative results directly at the patient's bedside within minutes, the EG7+ cartridge enables physicians and emergency medical teams to make swift, life-saving therapeutic interventions without waiting for centralized laboratory turnaround times.
