2006 CDC Testing Recommendations
 HIV screening is recommended for all clients age 13-64 in
healthcare settings, especially individuals in care for other
STIs or women considering conception/pregnancy
 HIV test should be performed unless the client specifically
declines
 HIV screening should be voluntary and free from coercion
 Oral or written information should be provided at the time of the test
 General consent for medical care is sufficient for HIV testing, except
where state laws require separate consent
 Prevention counseling should not be required as part of HIV
screening
 High risk clients should be screened every year
