最好是用醫院的尿液檢測(urine chemistry)專用試紙,可以找診所、藥局幫忙或Google就可查到。 pH test strips
========================== 相關醫學資料 Uric Acid Nephrolithiasis: Recent Progress and Future Directions Persistently Low Urinary pH In aqueous solutions at 37°C uric acid has a solubility constant (Ksp) of approximately 100 mg/L, whereas urate is 20 times more soluble.43 At a pH equal to the pKa, uric acid and urate exist in equal proportions as a consequence of the Henderson-Hasselbach equation. Hence, if 200 mg of urate were introduced into a 1-L aqueous solution with a pH of 5.5 at 37°C, 100 mg would become uric acid and the remainder would continue to be urate. In contrast, if 1200 mg of urate were instilled into a similar volume at a pH of 6.5, 1100 mg would remain in the soluble urate form.
These relationships are based on the upswing of the uric acid dissociation curve at this pH, which plateaus at a pH of approximately 7.2.
