i-STAT CG4+ cartridge (blue), List No. 03P85-50. UDI (01) 00054749002269 - Product Usage: The i-STAT CG4+ cartridge is intended for the quantitative measurement of lactate, pH, pCO2, and pO2 in venous, arterial or capillary whole blood.
Official recall recorded by the U.S. Food & Drug Administration.
The hazard
The I-STAT BLUE CHEM8+ and CG4+ cartridges are not FDA cleared and do not have CLIA waived status. CLIA recognizes two types of laboratory tests: waived and non-waived. Different CLIA standards apply to waived and non-waived tests as well as the facilities that perform these types of tests. The i-STAT CHEM8+ cartridge contains nine measured assays (sodium, potassium, chloride, blood urea nitrogen (BUN), ionized calcium, TCO2, glucose, creatinine and hematocrit) and is categorized as a CLIA waived test for venous whole blood samples, meaning this cartridge could be used in a facility with a CLIA Certificate of Waiver as a waived test.
