Testing for toxoplasmosis in pregnancy: a study of the routines in primary antenatal care

Abstract

Objectives: The question of benefit of screening for antibodies against Toxoplasma gondii in pregnancy to prevent impairment in the infant has not been settled. Despite this, it is believed that such testing is common. The aim of this study was to describe the test routines and to identify factors associated with testing in primary antenatal care. Setting: Ulleval University Hospital, Oslo, Norway. Methods: All women who gave birth at Ulleval University Hospital, Oslo, Norway, in May 2000 were included. The number of antibody tests during pregnancy was obtained from the patient registry at the department of microbiology at the same hospital. Results: 81% (361/446) had been tested for antibodies against Toxoplasma gondii during pregnancy. Women attending primary antenatal care at a specialist in obstetrics and gynaecology were most likely to be tested. Among women with no signs of prior toxoplasmosis, 35% (110/317) were tested only once. Discussion: The majority of pregnant women are being tested for toxoplasmosis even though such testing has no documented preventive effect and has not been recommended.
