Pregnancy tests can sometimes get it wrong

Negative pregnancy tests can be misleading, according to a recent report.


A severely dehydrated woman was admitted to hospital with vomiting and vaginal discharge. She had gone nine weeks without a menstrual period. A pregnancy test concluded that she was not pregnant, but a physical examination suggested otherwise. An ultrasound scan revealed that she was carrying triplets.


Say the doctors, high levels of human chorionic gonadotropin – common in multiple pregnancies – can inhibit the antigen-antibody reaction on which many pregnancy tests are based (J Obstet Gynaecol, 2002; 22: 442).
