Meanwhile, in patients without kidney dysfunction, the timing for biopsy was determined by the amount of proteinuria; for example, 66.9% of patients with hypoalbuminemia (Alb <3.0g/dL) underwent biopsy within 1 month, while 68.2% of patients with 0.3 g/gCr ≤ uTP/Cr < 0.5 g/gCr of proteinuria were followed up for at least 6 months before biopsy. This evidence concerns the gene ALB and Hypoalbuminemia.
