Code and name of test:
4806 Urine pH
The pH indicates the capacity of the renal tubes to maintain the acidic-basic balance of the plasma and extracellular fluid, which is achieved by the reabsorption of the sodium and the tubular secretion of hydrogen and ammonium ions.
The urine pH detection test is based on a combination of three indicators: red-methyl, bromothymol blue and phenolphthalein. At a pH of 5.9 a graduation of colour from orange to greenish yellow and blue is obtained.
- The importance of urine pH consists primarily of determining the existence of a systemic acidic-basic disorder of metabolic or respiratory origin and the management of the urinary conditions that require maintaining the urine at a specific pH, such as kidney stones (the aim is to change the urine pH through diet and treatment so as to prevent kidney stone formation), urine alkalinisation under a treatment with sulphonamides (the prevention of crystal formation) or intoxication with salicylates (the increase of excretion) during transfusions. The urine should be kept acidic during the treatment of urinary tract infections.
