Post-streptococcal glomerulonephritis (PSGN) classically presents with hypertension, edema, macroscopic hematuria, acute renal failure, proteinuria, and an active urine sediment with red blood cells and red blood cell casts. A patient who developed PSGN but who had only minimal and transient abnormalities in the urinalysis is reported. Physicians should be aware that a normal urinalysis does not rule out the diagnosis of PSGN.
