The difference between selective proteinuria and nonselective proteinuria lies in the molecular weight size of the filtered proteins. Selective proteinuria is free of large proteins, while nonselective proteinuria has large proteins such as I Immunoglobulin G and complement.
1. Selective proteinuria, the main components are proteins with medium relative molecular mass, such as albumin.
2. Non-selective proteinuria, in addition to the above proteins, there are large molecule proteins in the urine, such as immunoglobulin, complement, etc., which indicates that the glomerular filtration membrane is severely damaged, and the appearance of non-selective proteinuria often suggests that the prognosis is poor.
Selective proteinuria and non-selective proteinuria are both manifestations of glomerular damage, it is recommended to go to a regular hospital, complete the relevant examinations under the guidance of the doctor, and follow the doctor’s instructions for standardized treatment.
