Unicel dxc 600i synchron

Blood was drawn via venipuncture and high sensitivity CRP levels were measured using the SYNCHRON System(s) High Sensitivity C-Reactive Protein reagent. The system portioned out one-part sample to 26-parts reagent into a cuvette and monitored change in absorbance at 940 nanometers. This change is proportional to the concentration of CRP and is used to calculate the concentration based on a single-point adjusted, pre-determined calibration curve. There was a change in lab equipment during the 2015-2016 survey cycle from the Beckman Coulter UniCel DxC 600 Synchron chemistry analyzer to the Beckman Coulter UniCel DxC 600i Synchron chemistry analyzer. An internal comparison study was reported to indicate no statistical adjustment was required to correct for this change. Specimens were frozen at −70 °C until the day of the assay. Samples were run singly as part of a Multi-analyte Biochemistry Panel. Lower limit of detection for CRP was .08 mg/L (values lower than this were set to .08 mg/L). Participants were asked to fast the morning of the blood draw.
