What does a plus sign for urine protein mean?

Urine protein (+) refers to the presence of a small amount of protein in the urine, which represents the possible presence of kidney-related diseases and requires further examination of kidney function, 24-hour urine protein quantification and other items to determine the condition. In clinical practice, common causes that can cause urine protein, including glomerulonephritis, nephrotic syndrome, diabetic nephropathy, etc., require treatment plans based on specific conditions and causes. Generally speaking, ACEI or ARB is the preferred drug. In the process of treatment, attention is paid to monitoring changes in the condition, and if the patient’s condition deteriorates, drug interventions such as hormones and immunosuppressants need to be applied according to the specific type of pathology. In daily life, pay attention to the principles of low-salt, low-fat, high-quality, low-protein diet.
