What Does a Plus Sign in a Urine Test Indicate?

1. Urine testing refers to routine urine analysis. A plus sign in the routine urine analysis indicates a potential risk of infection, but the interpretation of a plus sign is too general and should be analyzed based on specific test indicators.

2. This test involves collecting a urine sample from the patient and analyzing the results to understand urine color, urine sediment, red blood cells, white blood cells, etc. If the test results show a plus sign for white blood cells, it suggests that the patient has a urinary tract infection. Generally, after drinking more water and urinating more frequently, the body will return to normal. If urine protein is positive, it may indicate glomerular disease or renal vascular disease. If red blood cells are positive, it indicates that red blood cells are being destroyed. After receiving the test results, one should actively seek further examination in the hospital to identify the underlying cause.

3. Before the test, females should avoid menstruation to prevent blood from mixing with the urine. In the days before the test, they should also maintain a light diet, avoid smoking and drinking alcohol to improve the diagnostic accuracy of the disease. Avoid strenuous exercise and excessive water intake.
