CRP level
Log transformed level of C-reactive protein
This variable is only available in MAP and MARS.
C-reactive protein (CRP) level is quantified from serum samples using highly sensitive multiplexed sandwich enzyme-linked imunosorbent assay (ELISA) arrays by Endogen Searchlight technologies (Billerica, MA). CRP values were adjusted by a correlation factor supplied by Endogen Searchlight based on data obtained from recalibration studies. See the inflammatory markers subcategory description for more information.
This variable is expressed in ug/mL and is log transformed.
