High-sensitivity CRP (hsCRP) levels in Lifelines participants were determined in blood samples using three different lab-methods (section: Physical state.
The difference between the three methods are stated in the table.
hsCRP in heparin (mg/L) hscrp_result_all_m_2 LCRP ~49k - 8+ hsCRP in serum (mg/L) hscrp_result_all_m_1 SCRP ~8k - 8+ hsCRP in heparin (mg/L) hscrp_result_all_m_3 CRPH ~1k ~500 8+
Variable name | Kit name | Supplier name | Tube type | Conversion | Participants | |
---|---|---|---|---|---|---|
hscrp_result_all_m_1 | SCRP | CardioPhase hsCRP | Siemens (BNII) | Serum | 0.92 x old - 0.01 | ~49k |
hscrp_result_all_m_2 | LCRP | CardioPhase hsCRP | Siemens (BNII) | Heparin(ized plasma) | ~1.5k | |
hscrp_result_all_m_3 | CRPH | CRPL3 | Roche (Modular) | Heparin(ized plasma) | ~500 |
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 to collect the sample.
This causes differences in the measured values. SCRP values can be converted to LCRP using the formula: 0.92X - 0.01.
