HIV-antibody testing has been carried out as a routine among pregnant women in Norway since September 1987. Up to September 1991 (later information is incomplete) 339,823 women have been tested. 25 of these were positive. In this survey we interviewed by questionnaire 55 physicians and nurses who had been asked for a second blood sample from their patients. None of the physicians who had tested the 25 HIV-positive women were included. Among these 55, nine stated that the women had suffered psychological distress after the second testing, and one reported that the woman in question had chosen to have an abortion. The study demonstrates possible opportunities for improving the handling of information, both between laboratories and physicians/nurses and between physicians/nurses and the women who are asked to give a second blood sample. We also interviewed 290 physicians who had asked for a HIV-test for pregnant women but had received no false positive results (the number of respondents was 258). Among a total of 379 physicians and nurses, one third stated that they seldom or never asked explicitly if the woman wanted to be tested. 88% were in favour of routine testing and 97% reported a positive or very positive attitude among the pregnant women towards screening. Nearly one third stated that they had insufficient knowledge about the significance of a false positive test result.
