title: False positive immunoreaction in products of conception.
abstract: False positive immunostaining for cytomegalovirus in products of conception was revealed using an avidinbiotinylated peroxidase complex. The cause was shown to be endogenous biotin. The use of a non-avidin-biotin method avoided the problem.
