Hemoglobin electrophoresis: an important investigation in the evaluation of patients with massive hematuria.

Sir, We report a case of a 34-year-old Nigerian woman who presented at the renal clinic of a University Hospital in Nigeria in July 2003 with a history of sudden onset of painless, profuse and persistent hematuria. She had fever and rigors at the onset of illness which were relieved by antipyretics. There were no other urinary symptoms; neither did she have sore throat, skin rash, abdominal pains nor bone pains. She denied use of any herbal mixtures or abuse of analgesics. She was engaged in subsistent farming and lived in the village.
