Urine co2 determination

The urine co2 assay is an ancillary test for examining the normalization of renal tubular acidification. Common sodium bicarbonate load test, neutral phosphate load test, sodium sulfate test, furosemide test, 24-hour urate test and HCO3-reabsorption test. Normal human urine PCO2 should be >9.3 kPa, or 2.67 kPa higher than blood PCO2. For example, a difference of 15% between urine and blood PCO2 can determine proximal renal tubular acidosis. Basic Information Specialist classification: urinary examination classification: urine / kidney function test Applicable gender: whether men and women apply fasting: not fasting Tips: Maintain regular routines and diet to help the inspection go smoothly. Normal value Normal human urine PCO2 should be >9.3 kPa, or 2.67 kPa higher than blood PCO2. Clinical significance Abnormal results: 15% difference between urine and blood PCO2 can determine proximal renal tubular acidosis. The people who need to be examined: suspected to be renal tubular acidification. Precautions Taboo before the examination: Maintain regular routines and diet to help the inspection proceed smoothly. Requirements for the examination: The doctor asks the patient to dispel the ideological concerns and cooperate with the trial. According to the doctor's instructions, the patient actively cooperated with the doctor for examination, and the doctor carefully examined and carefully observed the results. Inspection process Blood HCO3- levels can be alkaline or acidic. 24h urine HCO4-only titratable acid is normal, urinary calcium can be increased or normal (the urine can be perfused with NaHC03 when urine PCO2 is measured, when urine pH> blood pH, urine PCO2> blood PCO2, 2.66kPa or more It has diagnostic significance). Not suitable for the crowd Inappropriate people: Generally, there is no suitable for the crowd. Adverse reactions and risks No related complications or hazards.
