What does kidney two plus sign mean

summary

A few days ago, I was not feeling well, so I went to the hospital for an examination. The result of the urine test was two plus signs of urinary protein. At that time, the doctor didn't say anything, but I was still very worried with this report, just like understanding this. Now let's learn what the two plus signs mean.

What does kidney two plus sign mean

First: urine protein 2 +, which indicates that there is still more leakage protein in urine. When encountering cold, infection and other factors, it will lead to immune allergy and produce immune complex by combining anti-inflammatory antibody.

Second: urine protein and occult blood in normal circumstances is negative, that is, should be minus sign. Positive is plus sign, suggesting that there may be kidney disease. The leakage of protein and occult blood in urine may damage the renal parenchyma. Due to the deposition of a large number of immune complexes on the glomerular basement membrane, the basement membrane is destroyed and the permeability increases.

Third: there are two plus signs for urinary protein. If the possibility of physiological urinary protein is excluded, it can be determined to a large extent that the production of urinary protein is kidney injury. In most cases, there is only a small amount of urine protein in the urine of healthy people, generally 40-80 mg, up to 150 mg, which is called physiological urine protein.

matters needing attention

In fact, the occurrence of urinary protein 2 + can not prove that the patient has kidney disease, which needs further observation. If the possibility of physiological urinary protein is excluded, it can be determined to a large extent that the production of urinary protein is kidney damage.
