How would a protein leak be determined? He has bounced between Stage 3 a and b and back to low a since first told about it in Jan 2020. He previous doctor never said anything and to be honest I didn't know to pay attention to a GFR. He had a test which showed a vascular insufficiency and was told to wear compression stocking on right leg. Dr in AZ said he didn't think he needed them as his leg was constantly elevated by his recliner and the stocking was bothering him in summer heat (getting lots of bruising/sores on both legs). Lately has been having more and more problems with memory issues.

Thank you.
