This study investigated the prevalence of home pregnancy kit use, incidence of false-negative results, and compliance with testing procedures. Among 144 pregnant women, identified through three health care settings, prevalence of test-kit use was 28.5 per cent. The false-negative rate was 24.3 per cent. Total compliance with instructions was reported by only 32 per cent of users. Women testing less than nine days after menstrual period was due had false-negative rates of 33 per cent contrasted with 21 per cent for those testing after the nine days.
