... zero standard. For direct capture this was found to be 13 ng/mL, for homogenous sandwich Assay 20 ng/mL and for the direct Sandwich Assay 3 ng/mL. Precision for the direct sandwich assay was determined using ... sensitive method for quantification of CRP. The lower limit of detection for the direct assay and the homogenous sandwich assay were both 20 ng/mL whereas for...
