Proposals to make prenatal HIV testing routine and universal dramatize ethi
cal issues regarding early detection of HIV. These proposals would abolish
pretest counseling and written informed consent for prenatal HIV testing. E
thical concerns include whether pregnant women are adequately informed that
they may refuse such testing and whether patients have an opportunity to o
btain more detailed information about the benefits and risks of HIV testing
in this context. Several pertinent research questions need to be studied,
including whether pregnant women find routine universal HIV testing accepta
ble and whether safeguards adequately protect women who receive testing. If
analogous policies to enhance early detection of HIV are considered in oth
er clinical contexts, the important clinical and ethical differences betwee
n vertical transmission and other situations of HIV transmission must be ke
pt clearly in mind.
