Siemens DF33B Creatinine (CREA) Flex® Reagent Cartridge – 480 Tests

The Siemens DF33B Creatinine Flex® is a high-volume in vitro diagnostic (IVD) reagent designed for the quantitative determination of creatinine in human serum, plasma, and urine. This assay is a critical tool for clinicians in assessing renal function, calculating Glomerular Filtration Rate (GFR), and monitoring patients with kidney-related pathologies.

Specifically engineered for the Siemens Dimension® integrated chemistry systems, the DF33B utilizes the modified Jaffe methodology to deliver rapid, precise, and standardized results. The "Flex" cartridge design allows for "load-and-go" efficiency, featuring a ready-to-use format that requires no manual reagent preparation, thereby minimizing the risk of human error and reducing laboratory downtime.
