- What units is pH (Urine) measured in?
- pH (Urine) is most commonly reported in pH. Labs in different countries may use other units — you can convert between them with BloodId's blood test unit converter.
- Where do pH (Urine) reference ranges come from?
- BloodId uses ABIM standard reference ranges and educational information from MedlinePlus (see our methodology). Reference ranges still vary by lab, age, and sex, so always compare against your own report.
- Can I track pH (Urine) over time?
- Yes. Upload results from any lab and BloodId charts your pH (Urine) over time against its reference range, so you can see whether the trend is rising, falling, or stable.
