A urinalysis showing 1+ urine protein is mostly considered proteinuria, which means that there is a small amount of protein in the urine. Ascorbic acid (i.e., vitamin C) 1+ usually means that vitamin C in the urine is higher than normal. If an abnormal urine test is found, it is recommended to go to a regular hospital in time. Urine protein 1+ can usually be seen in physiological elevation such as after strenuous exercise, consuming a large amount of high-protein diet, standing for a long time, etc.; it can also be seen in pathological elevation such as acute and chronic glomerulonephritis, acute pyelonephritis, nephrotic syndrome, IgA nephropathy, diabetic nephropathy, hypertensive nephropathy and other diseases. Ascorbic acid 1+ usually does not have much clinical significance, and the value of its elevation mainly lies in determining the reliability of the test results, and is mainly used to detect false-negative or false-positive urine tests. If abnormalities are found in urine tests, it is recommended to consult a doctor and follow the doctor’s instructions for standardized diagnosis and treatment.
