Posttranslationally Modified Fetuin-A in Urine as a Marker for Renal Dysfunction (Patients With Chronic Kidney Disease - With or Without Kidney Transplantation).

In this monocentric prospective cohort study, we will measure uPTM-FeA by enzyme-linked immunosorbent assay (ELISA) kit DNLite IVD 103 in cooperation with PromedeusLab. Human uPTM3-DKD ELISA is a colourimetric immunoassay for quantitatively determining human unique Fetuin-A with specific post-translational modification (PTM) in urine.
