Dedicated blood gas panel for rapid acid-base and oxygenation assessment
Product overview
The i-STAT G3+ is a dedicated blood gas cartridge that delivers results in approximately two minutes at the bedside. Respiratory therapists and nurses can assess acid-base disturbances and oxygenation status without sending samples to the central lab. The cartridge measures pH, partial pressure of carbon dioxide (PCO2), and partial pressure of oxygen (PO2) directly, with TCO2, HCO3, base excess, and sO2 calculated from the measured values. Abbott's STATNotes feature provides on-screen reference information for each analyte, helping clinicians interpret results at the point of care without needing to consult external references.
Expand your point-of-care testing capacity with refurbished i-STAT analyzers
If your facility relies on the Abbott i-STAT system for point-of-care testing, Block Scientific can help you increase your testing capacity at a fraction of the cost of buying new. The Abbott i-STAT is one of Block Scientific's Centers of Excellence analyzers, which means we carry deep inventory, provide factory-level refurbishment, and back every unit with comprehensive service and support.
Adding refurbished i-STAT 1 or i-STAT Alinity instruments to your fleet lets you deploy more analyzers across departments, satellite locations, or mobile units without the capital outlay of purchasing new. Every refurbished i-STAT from Block Scientific is thoroughly tested, calibrated, and verified to meet original manufacturer specifications before it ships.
And when you bundle your cartridge and consumable orders with refurbished instrumentation, you get the best possible pricing on both. Complete the form on this page and your local sales rep will contact you to discuss your application.
Clinical evidence
The G3+ has demonstrated particular value in respiratory therapy and neonatal intensive care (NICU) settings. In respiratory care, therapists can run a blood gas at the bedside, get results in two minutes, and immediately adjust ventilator settings or medication doses without waiting for central lab turnaround. In the NICU, the ability to collect a 95 uL capillary sample via heel stick means clinicians can monitor blood gases frequently without drawing the larger volumes required by central lab analyzers. For low birth weight neonates, where total blood volume may be as little as 80 mL, this blood conservation is clinically significant. More frequent monitoring with smaller draws means better respiratory management with less iatrogenic blood loss.
Clinical applications
Primarily used in respiratory care for monitoring patients with severe lung diseases and rapidly assessing pulmonary status after ventilation or medication changes. Also valuable in neonatal care and NICU settings, where the small capillary sample volume (95 uL) reduces total blood volume collected from fragile patients. Heel stick capillary collection is supported, making the G3+ practical for even the smallest patients. Physicians can assess respiratory function more frequently and evaluate ventilator needs, and the rapid two-minute turnaround supports real-time clinical decisions rather than reactive adjustments based on delayed lab results.

Intended use
Intended for use in the in vitro quantification of pH, partial pressure of oxygen (PO2) and partial pressure of carbon dioxide (PCO2) in arterial, venous or capillary whole blood in point-of-care or clinical laboratory settings. Used in the diagnosis, monitoring, and treatment of respiratory, metabolic and acid-base disturbances.
Frequently Asked Questions
The G3+ is a dedicated blood gas-only cartridge. It does not include electrolytes, chemistries, or hematology parameters. If you need blood gases combined with electrolytes, consider the EG6+, EG7+, CG4+, or CG8+ cartridges.
Yes. The G3+ accepts arterial, venous, and capillary whole blood samples. The 95 uL sample volume can be obtained via capillary draw, making it suitable for neonatal and pediatric applications.
pH, PCO2, and PO2 are directly measured by sensors in the cartridge. TCO2, HCO3, base excess (BE), and sO2 are calculated from the measured values using standard equations.
