Abstract:
During the routine tests, it's found that the testing method related to Hemodialysis mentioned in the industry standard YY0598-2006 cannot reflect the real bicarbonate concentration in Hemodialysis. To discuss the reaction principle and its interference factors deeply by studying the assay determination of bicarbonate in Hemodialysis, and it could be cited as reference for amending the quality standard or troubleshooting. The improved way of determining bicarbonate concentration in Hemodialysis is also put up.

Diagnosing Acidosis and Alkalosis
First, the pH level is assessed to determine whether the blood pH is normal (7.35–7.45), low (acidosis), or high (alkalosis).
Next, the PCO2 and HCO3− values are examined to...

Renal Regulation of Acid-Base Balance
In the kidneys, cells within the proximal convoluted tubules (PCT) and the collecting ducts secrete hydrogen ions (H+) into the tubular fluid. Specifically, in the PCT, Na+/H+ antiporters secrete H+ while reabsorbing Na+.
