What does it mean to be 3+ but negative for urine protein?

Urine protein 3 (++++), refers to the presence of protein 3 (++++) in the urine. Negative is the latter reference range, which indicates that protein should not be present in the urine. So this condition often represents kidney damage, and the more common causes are nephrotic syndrome, glomerulonephritis, hypertensive kidney damage, IgA nephropathy, diabetic nephropathy, etc. In this case, further examination of 24hUP quantification is needed to assess how much protein is leaked, and then a renal puncture is performed to clarify the specific type of pathology, so that hormonal or immunosuppressive therapy can be chosen. For those who have small urine protein quantification, they can also apply ACEI or ARB drugs alone to reduce urine protein, and take oral Bering capsules to protect the kidneys, which also has a certain auxiliary effect on the treatment of kidney disease. Pay attention to regular review of the relevant indicators at the hospital and adjust the drug treatment plan according to the results.
