title: High levels of hCG in choriocarcinoma can result in renal failure and a false-negative pregnancy test in men.
abstract: The diagnosis of choriocarcinoma was delayed because a urinary pregnancy test for hCG was falsely negative. This man's hCG rose to 25,000,000 iu/l. He developed renal impairment, probably due to precipitation of hCG in his renal rubules.
