Proteinuria Glomerular proteinuria 2021-05-02T22:02:41Z A type of proteinuria characterized by increased permeability of the glomerular capillary wall to macromolecules (particularly albumin), whereby protein excretion can reach 20 g/24 h and consists mainly of albumin. In contrast to glomerular proteinuria, tubular proteinuria is generally less than 1-2 g/24 h. In tubular proteinuria, although albumin remains a significant component, there is a relatively much greater increase in proteins of smaller than 60 000 Da
