Drinking water may affect the urine protein test.
Urine protein tests include both qualitative and quantitative tests. Qualitative tests identify the presence or absence of protein in the urine, while quantitative tests identify the amount of protein in the urine.
Drinking water may have an effect on the qualitative test, especially if drinking large amounts of water causes dilution of the urine, which may result in a false-negative urine protein result. Drinking water has less of an effect on quantitative testing. If there is protein loss, the amount of protein lost is a certain amount, and sometimes dilution can lead to low measurements.
Before the urine protein test, try to avoid drinking water, at the same time, when the specimen must be retained in accordance with the requirements, if necessary, can be reviewed, found abnormal, and timely compliance with medical advice and treatment.
