Blood gases with electrolytes, ionized calcium, and hematocrit in a single rapid test
Product overview
The i-STAT EG7+ cartridge combines blood gas analysis with key electrolytes, ionized calcium, and hematocrit in a single test that delivers results in approximately two minutes. This combination panel is designed for critical care settings where multiple parameters need to be assessed simultaneously from a single sample. The cartridge directly measures sodium, potassium, ionized calcium, hematocrit, pH, PO2, and PCO2, with hemoglobin, TCO2, HCO3, base excess, and sO2 calculated. The calculated bicarbonate (HCO3) value is clinically significant as it reflects the metabolic component of acid-base status and helps differentiate respiratory from metabolic acidosis or alkalosis. Sodium measurements are traceable to NIST SRM 956, and all electrolyte sensors are calibrated against reference standards to ensure correlation with central lab methods.
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 applications
Supports the diagnosis and treatment of patients with hypertension, dehydration, cardiac distress, renal impairment, and cellular transport dysfunction. The blood gas values assess oxygenation and respiratory status. Particularly useful in ICUs, operating rooms, emergency departments, and anywhere that rapid, multi-parameter assessment is needed to drive immediate clinical decisions.

Specifications
Intended use
Intended for use in the in vitro quantification of Sodium, Potassium, Ionized Calcium, Hematocrit, pH, oxygen partial pressure, and carbon dioxide partial pressure in arterial or venous whole blood. Also for Sodium, Hematocrit, pH, PO2, and PCO2 in capillary whole blood.
Storage and handling
Cartridges should be stored refrigerated at 2 to 8 degrees Celsius. Once removed from refrigeration, cartridges can be held at room temperature (18 to 30 degrees Celsius) for up to 14 days. Allow cartridges to equilibrate to room temperature before use. Do not freeze or expose to temperatures above 30 degrees Celsius.
Frequently Asked Questions
The EG7+ includes ionized calcium in addition to everything on the EG6+. If ionized calcium is part of your clinical assessment (common in cardiac, surgical, and transfusion settings), the EG7+ provides that data without needing a separate cartridge.
The CG8+ adds glucose to the EG7+ analyte menu. If you need glucose as part of the same test, go with the CG8+. If glucose is not needed (or you are testing it separately), the EG7+ covers the rest.
Yes, but with a reduced analyte menu. Capillary blood supports sodium, hematocrit, pH, PO2, and PCO2. Potassium and ionized calcium require arterial or venous samples.
