Eating a moderate amount of meat before the 24-hour urine protein quantification test will not affect the results; eating a large amount of meat will affect the accuracy of the results. 24-hour urine protein quantification is often used to assist in the diagnosis of kidney-related diseases and to monitor treatment and prognosis. If the 24-hour urine protein quantification test is positive, it is mainly caused by the increase in glomerular filtration function, which makes it leak out of the filtration barrier. If more meat is consumed, the glomerular filtration will be increased, which may have some effect on the results of urine protein quantification. However, if you eat only normal meat, or even eat less meat, the result will not be affected. It is recommended to eat a moderate amount of meat and other high-protein foods (eggs, milk, tofu, etc.) before the 24-hour urine protein quantification test to avoid affecting the accuracy of the result. Patients with abnormal results of 24-hour proteinuria are advised to consult a regular hospital for further examination and to follow the doctor’s instructions for treatment and dietary adjustments.
