Drinking water, strenuous exercise, and nervousness can all affect the results. If the patient drinks a lot of water before taking the specimen, it will cause the urine to be diluted, and the urine protein test result will be low and false-negative. If the patient strenuous exercise or mental stress before the specimen, will lead to an increase in the glomerular filtration rate, urine protein will also increase, the test results may be false positive.
