Background Few studies have assessed the relationship between serum total carbon dioxide (CO) and bicarbonate ion (HCO ) concentration in patients undergoing peritoneal dialysis. We determined the agreement between serum total CO and HCO concentration and the diagnostic accuracy of serum total CO for the prediction of low (HCO <24 mEq/L) and high (HCO ≥24 mEq/L) bicarbonate concentrations in patients on peritoneal dialysis. Methods We collected 245 samples of venous blood from 51 patients on peritoneal dialysis.

We determined the agreement and discrepancy between serum total CO2 and HCO3- concentrations and the diagnostic accuracy of serum total CO2 for the prediction of low (HCO3- < 24 mEq/L) and high (HCO3- ≥ 24 mEq/L) bicarbonate concentrations in hemodialysis patients.
Methods: One hundred forty-nine arteriovenous blood samples from 84 hemodialysis patients were studied.
Background: We investigated the relationship between serum total carbon dioxide (CO) and bicarbonate ion (HCO) concentrations in pre-dialysis chronic kidney disease (CKD) patients and devised a formula for predicting low bicarbonate (HCO < 24 mmol/L) and high bicarbonate (HCO ≥ 24 mmol/L) using clinical parameters.
Methods: In total, 305 samples of venous blood collected from 207 pre-dialysis patients assessed by CKD stage (G1 + G2, 46; G3, 50; G4, 51; G5, 60) were investigated. The relationship between serum total CO and HCO concentrations was analyzed using Pearson's correlation coefficient.
