There are two types of HIV tests. The most commonly used
is an antibody test, which looks for the presence
of antibodies that your body creates against the HIV virus. These antibodies
may not show up for several weeks to a few months following infection.
The rapid tests, which can often be done orally, are antibody tests.
To get antibody testing, see this
page on the King County website.
The other kind of test looks for the HIV virus itself
(often called an HIV RNA or viral load test).
This test will become positive shortly after infection, so it is an
important tool for diagnosing those who have become infected with HIV
very recently. If you have reason to think you might be very newly
infected with HIV (check out a list of common
symptoms of acute infection), you can contact
the Primary Infection Clinic for possible HIV RNA testing or go
to the Public
Health STD Clinic at Harborview Medical Center and tell them you
are concerned about acute HIV infection.
