From the CDC report in case someone hasn't seen it.

We seem to haves waves of the "worried well" and it would be quite nice
to tell them two weeks instead of three months. (although I'd say 2
weeks and THEN 3 months).

UNITED STATES:
"New Test Detects HIV Infection at Earlier Stage"
Wall Street Journal (06.15.04)::Marilyn Chase
    A new HIV test combining aspects of traditional antibody testing
with
polymerase chain reaction testing, which amplifies small amounts of
virus,
may allow doctors to monitor treatment better and screen blood with more
speed and sensitivity than current tests. The Real-Time Immuno-PCR test
detects small amounts of the p24 protein in HIV, said Niel Constantine
of
the Institute of Human Virology at Baltimore's University of Maryland
School
of Medicine. The institute's chief is Robert Gallo, co-discoverer of
HIV.
    The efficacy of AIDS drugs can be measured by monitoring a
patient's
HIV levels, of which an increase can signal drug resistance. When drugs
lose
their effect, patients need to switch drugs. Most current tests of viral
load can detect 50 copies of HIV, while the Real-Time Immuno-PCR can
detect
just two copies, said institute researchers Janet Barletta and Daniel
Edelman. Barletta, Edelman and Constantine reported their findings in
the
July issue of the American Journal of Clinical Pathology.
   Constantine hopes the test will detect HIV faster than current
tests,
which can detect the virus in blood 12 days after infection. Validating
the
new test requires long-term study and Food and Drug Administration
approval.
    Constantine said his group is separately developing a simple and
cheap
battery-operated system for monitoring HIV treatment in the developing
world. The portable device, being co-developed with Norway's Blonor AS
under
a $200,000 Doris Duke Foundation grant, could operate in settings
without
dependable power or sophisticated laboratories.
