Yup, IgG crosses the placenta giving you a positive test result on the western blot....in a few months if test is repeated it will be gone!

Default correct answer :)

Correct answer is c) positive Western blot for HIV

In every newborn of HIV+ mother we would have both Western blot and ELISA positive (mother's IgG cross the placenta).
PCR would be positive only in infected newborns.

PCR is an diagnostic method in:
- newborns of HIV+ mothers
- early testing after known exposure to HIV-positive blood (needlestick) or other fluids/tissue
