As<unk>  is a subset of nephrotic syndrome, diagnosis involves looking for a combination of edema, high amounts of protein in urine, low albumin and high serum cholesterol. Initial workup can include a urinalysis, kidney function tests, serum albumin level and a lipid panel. Microscopic amounts of blood are present in the urine of 10-30% adults with<unk> . As<unk>  is the most common type of nephrotic syndrome in children, renal biopsy is not usually done in children under the age of 10 unless there are concerning features that are unusual for the<unk>  (high blood pressure, bloody urine, renal dysfunction) and if they fail to respond to corticosteroid therapy. These would suggest that it may not be<unk> . In adults, a renal biopsy is required as there is a much wider differential for nephrotic syndrome. As the name suggests, the renal biopsy of a patient with<unk>  would show<unk>  or no evidence of<unk>  in light microscopy, which is unique among the causes of nephrotic syndrome.
