Webb28 nov. 2024 · Normal urine pH is slightly acidic, with usual values of 5.5 to 7.5, but the normal range is 4.5 to 8.0. A urine pH of 8.5 or 9.0 often indicates a urea-splitting organism, such as Proteus, Klebsiella, or Ureaplasma urealyticum. An alkaline urine pH can signify struvite kidney stones, also known as "infection stones." [12] WebbpH = −log [H+] The square brackets around the H + automatically mean "concentration" to a chemist.
