HIV Screening Recommendations

All adolescents and adults aged 15-65 years should be screened for HIV at least once using an opt-out approach, with pregnant women screened during each pregnancy and high-risk populations screened at least annually. 1

General Population Screening

The USPSTF provides the most authoritative guidance, recommending routine HIV screening for:

  • Adolescents and adults aged 15-65 years (Grade A recommendation) 1
  • Younger adolescents and older adults at increased risk should also be screened 1

The CDC's 2006 recommendations, which remain current, specify ages 13-64 years unless the prevalence of undiagnosed HIV is documented to be less than 0.1% 2. The opt-out approach means patients are informed that HIV screening is part of routine care and will be performed unless they specifically decline, without requiring separate written consent or prevention counseling 2.

Rationale for Universal Screening

This expanded recommendation is based on evidence that:

  • Early identification and treatment with antiretroviral therapy (ART) substantially reduces AIDS-related events and death 1
  • ART decreases HIV transmission to uninfected sexual partners 1
  • Risk-based screening alone has failed to identify a substantial proportion of people with HIV 3

Pregnant Women

Screen all pregnant women during each pregnancy as early as possible using opt-out screening 4.

Repeat Testing in Pregnancy

Repeat HIV testing in the third trimester (preferably before 36 weeks) for women who: 4

  • Are at high risk for acquiring HIV infection
  • Receive care in facilities with HIV incidence ≥1 per 1,000 pregnant women per year
  • Are incarcerated
  • Reside in jurisdictions with elevated HIV incidence
  • Have signs/symptoms of acute HIV infection

Labor and Delivery Testing

Rapid HIV screening during labor/delivery should be performed for women with: 4

  • No documented HIV test during pregnancy
  • Unknown HIV status
  • Results available within 1 hour, 24 hours per day

If a rapid test is reactive during labor, immediately initiate antiretroviral prophylaxis while awaiting confirmatory results 4.

High-Risk Populations Requiring Annual (or More Frequent) Screening

Screen at least annually for individuals with: 2, 3

  • Men who have sex with men (MSM)
  • Unprotected sex with multiple partners
  • Past or current injection drug use
  • Exchange of sex for money or drugs
  • Sexual partners who are HIV-positive, bisexual, or injection drug users
  • Treatment for sexually transmitted diseases
  • Blood transfusion between 1978-1985

Special Consideration for MSM

For MSM specifically, consider screening every 3-6 months for those at particularly increased risk, though the evidence remains insufficient to mandate this frequency over annual screening 5. Each clinician should weigh individual risk factors, local HIV epidemiology, and testing policies when determining optimal screening intervals 5.

High-Risk Healthcare Settings

Prioritize screening in: 3

  • STD clinics
  • Correctional facilities
  • Homeless shelters
  • Tuberculosis clinics
  • Substance abuse treatment programs
  • Adolescent health clinics with high STD prevalence

Testing Methodology

Both traditional and rapid HIV tests have very high sensitivity and specificity 3. Rapid tests are preferred when immediate results are needed (e.g., labor and delivery) as they provide results within 1 hour and increase the likelihood patients receive their results 3.

Important Caveats

Acute HIV Infection

Patients tested during a viral syndrome suggestive of acute HIV infection may require additional testing beyond standard antibody tests, as antibody tests may not be reactive during acute infection 3.

Prevalence Threshold

The 0.1% prevalence threshold is reasonable for determining when routine screening may be discontinued 3. If no HIV-infected patients are found after screening approximately 4,000 patients, the 95% confidence interval for prevalence will be less than 0.1% 3.

Patient Education

Discuss HIV risk factors with all patients, particularly adolescents and older adults who may be unaware of behaviors that increase HIV risk 3.
