As summarized by Dr. Mayer, this case of proteinuria was really challenging because of various discrepancies between the history, clinical presentation, histology and laboratory data; however, soon after admission it became clear that the patient was faking kidney disease, i.e., albuminuria, acute renal failure and hyperkalemia by adding human albumin to her urine and abusing diuretics (loop diuretics and aldosterone antagonists), antihypertensives (ACE inhibitor, AT2 blocker and urapidil), NSAIDs and KCl tablets. Here, ALB is linked to Hyperkalemia.
