<p>A new test may help doctors uncover cases of infection in babies
</p>
<p> Pregnant women who harbor the AIDS virus have a 30% chance of
passing the infection on to their unborn children. But
conventional tests, which detect the presence of antibodies to
the virus, cannot determine which babies are infected and thus
need immediate treatment. The ambiguity occurs because the
mother's own antibodies cross the placenta, causing the newborn
to test positive even if it is not infected.
</p>
<p> Now scientists at UCLA believe they have found a solution.
In their study, published in the New England Journal of
Medicine, they used a new test that separates the maternal
antibodies from infant blood samples. No longer camouflaged, the
AIDS virus was easy to detect.
