What does urine protein 4+ mean?

Urinary protein 4+ refers to the presence of relatively more protein in urine, considered to be caused by pyelonephritis, diabetic nephropathy, hemolytic anemia, etc.

1, pyelonephritis

patients renal tubular structure, function damage, will affect the normal filtration of small molecular weight protein reabsorption, and then cause urinary protein 4+.

2, diabetic nephropathy

diabetic nephropathy patients glomerular filtration membrane damage, protein filtration excessive renal tubular reabsorption, can cause urinary protein 4+.

3, hemolytic anemia

hemolytic anemia patients plasma small molecular weight protein abnormal increase, beyond glomerular reabsorption, can lead to urinary protein 4+.
