Urine pH

Urine acidity is the pH value of the urine. The right reflects the ability of the kidneys to regulate the acid-base balance of body fluids. Under normal dietary conditions, the urine pH of normal people is 4.6-8.0 (average 6.0). Urine pH is mainly determined by renal tubular secretion of H +, secretion of titratable acid, formation of ammonium, and reabsorption of bicarbonate. Among them, the most important is acidic phosphate, alkaline phosphate or relative content, such as the former More than the latter, urine is acidic, but it is neutral or alkaline.
