i-STAT CG8+ Cartridges

The i-STAT CG8+ is one of the most comprehensive point-of-care cartridges available for the i-STAT handheld analyzer, delivering a full panel of critical results from a single sample in minutes. For clinicians working in emergency departments, ICUs, cardiac catheterization labs, and pre-hospital settings, this cartridge answers the questions that can't wait: What are the blood gases? Where is the patient's electrolyte balance? Is oxygenation adequate?

A single CG8+ cartridge reports arterial blood gas values (pH, PCO₂, PO₂), electrolytes (sodium, potassium, ionized calcium), hematocrit, hemoglobin, and total carbon dioxide, along with calculated values including base excess, bicarbonate, and oxygen saturation. That breadth is why the CG8+ is a mainstay for rapid assessment of critically ill and unstable patients, where drawing blood, running it, and acting on results all need to happen at the bedside.

Because it runs on the same i-STAT platform as other cartridges, the CG8+ fits seamlessly into workflows that already use point-of-care testing, requiring only a small whole-blood sample and delivering lab-quality results without transport delays. Buyers evaluating these cartridges typically weigh shelf life, storage temperature requirements, and lot consistency—CG8+ cartridges are refrigerated and should be brought to room temperature before use, and each shipment ships with lot information to support your quality control protocols.

Maintaining reliable results depends on regular verification of your analyzer and cartridges. To support that, pair your testing supplies with the appropriate calibration and quality control materials in our iSTAT Tricontrols collection, which provides the control solutions used to confirm your CG8+ cartridges and instruments are performing within expected ranges.

Whether you're stocking a hospital's rapid-response cart or equipping a mobile care unit, the i-STAT CG8+ delivers the combined blood gas, electrolyte, and hematology profile that supports fast, confident clinical decisions.
