What is a viral load test?
Preventing HIV from multiplying is another important goal
of HIV treatment. e viral load test measures the amount of
HIV in the blood. It’s the best measure of how well anti-HIV
medications are controlling the virus.
e best sign that treatment is working is reaching and
maintaining an . An undetectable
viral load doesn’t mean that you’re cured. It means that the
amount of HIV in your blood is too low to be detected by
the viral load test.
Once you start treatment, you should have a viral load test
within 2 to 8 weeks and then once every 4 to 8 weeks until
your viral load is undetectable. You need the test done only
every 3 to 4 months once your viral load is undetectable. If
you have an undetectable viral load for more than 2 or 3
years, your health care provider may recommend viral load
testing once every 6 months.
What causes treatment to fail?
HIV treatment can fail if anti-HIV medications are unable to
control the virus or protect the health of the immune system.
Sometimes treatment fails because of things you can’t control,
such as unmanageable side eects from anti-HIV
medications, interactions between anti-HIV medications and
other medications you take, or the body’s poor absorption of
anti-HIV medications.
Treatment can also fail because of
drug resistance
.
Sometimes HIV changes form and becomes resistant to
(not aected by) the medications in a regimen.
It may be necessary to change medications to deal with these
problems.
Can skipping medications cause treatment
failure?
Poor
treatment adherence
is another reason HIV treatment
can fail. Skipping medications allows HIV to multiply,
increasing a person’s viral load. To reach and maintain an
undetectable viral load, it’s important to closely follow your
treatment regimen. Poor treatment adherence can also give
HIV a chance to change form, leading to drug resistance.
Sometimes working with your health care provider to
improve adherence can prevent treatment failure. For
