Does the Exposure of Urine Samples to Air Affect Diagnostic Tests for Urine Acidification?

[摘要] Background and objectives For accurate measurement of pH, urine collection under oil to limit the escape of CO2 on air exposure is recommended. This study aims to test the hypothesis that urine collection under oil is not necessary in acidic urine in which bicarbonate and CO2 are minor buffers, because loss of CO2 would have little effect on its pH.
