High-sensitivity CRP (hsCRP) levels in Lifelines participants were determined using three different lab-methods.
The difference between the three methods are described in the table.
CRPH and LCRP only differ in the supplier. This does not have an effect on the measured values. SCRP differs from CRPH and LCRP in the type of tube used. This does cause differences in the measured values. SCRP values can be converted using the formula: 0.92X - 0.01.
