Background/Aims: Beta-trace protein (BTP) is a low-molecular-weight molecule. which may be used to assess residual renal function (RRF) in dialysis patients. Here we evaluated the influence of hemodialysis (HD) and hemodiafiltration (HDF) on plasma BTP. and analyzed the inter- and intra-individual variability of plasma BTP over time in HD and peritoneal dialysis (PD) patients. https://www.spidertattooz.com/Bottle-Logic-Tropical-Hideaway-16oz-Can/
