From: Comparative measurement of CNP and NT-proCNP in human blood samples: a methodological evaluation
Concentrations of CNP and NT-proCNP in blood samples. a) Concentration of CNP in serum, plasma and full blood samples (means, 95% confidence intervals). CNP concentrations in plasma samples are significantly higher compared to serum and full blood samples at all time points (ANOVA, p = 0.001 at baseline, p < 0.001 at 30’ and p = 0.003 at 120’). There is no significant difference between serum and full blood samples at any time point (ANOVA, p > 0.05). b) Concentration of NT-proCNP in serum, plasma and full blood samples (means, 95% confidence intervals). There is no significant difference between the groups at any time point (ANOVA, p > 0.05).
