Evaluation of the new generation of urinary pregnancy tests

Five new enzyme-linked urinary pregnancy tests were compared with the older hemagglutination assay. Urine came from 60 patients with a simultaneous serum beta-subunit of human chorionic gonadotropin determination. The new enzyme-linked kits have improved sensitivity with fewer false positive results than the older system. Some kits are clearly quicker and simpler to use than others.
