CRP samples diluted using VITROS Chemistry Products Specialty Diluent, VITROS Chemistry Products FS Diluent Pack 3, or a sample with a low concentration of CRP had positively biased results if the endogenous level of CRP in the diluent is not subtracted from the final result. The IFUs do not provide specific instructions for how to account for endogenous CRP in the diluent when calculating the sample result. Orthos diluents used to dilute samples containing CRP are manufactured using human plasma based fluids that contain endogenous CRP. Without accounting for the CRP in the diluent and removing its contribution from the result, the reported result will include the CRP present in both the sample and diluent, possibly leading to positively biased results.
