Product Summary

The Parameter Creatinine assay is a 30 minute chemical analysis designed to measure Creatinine in urine.

Precision

Intra-Assay Precision (Precision within an assay) Three samples of known concentration were tested on one plate to assess intra-assay precision.

Inter-Assay Precision (Precision between assays) Three samples of known concentration were tested in separate assays to assess inter-assay precision.

Urine
 

Recovery

The recovery of Creatinine spiked to levels throughout the range of the assay was evaluated.

Linearity

To assess the linearity, nine urine samples were serially diluted with deionized or distilled water and assayed in two lots of kit reagents.

Preparation and Storage

• Storage

  Storage conditions vary by component. See product insert for storage instructions.

Background: Creatinine

Creatinine is a non-enzymatic metabolite of phospho-Creatine, a molecule used primarily by muscle tissue as a store for high-energy phosphate that can be utilized for the production of ATP. Creatinine diffuses into the blood and is excreted by the kidneys at a relatively constant rate. Creatinine levels in the urine are used as a measurement of renal function.
