What does it mean when your HIV is suppressed?
Viral suppression is defined as having less than 200 copies of HIV per milliliter of blood. HIV medicine can make the viral load so low that a test can’t detect it (called an undetectable viral load ). If your viral load goes down after starting HIV treatment, that means treatment is working.

The amount of HIV in the blood is called viral load . Taking your HIV medicine as prescribed will help keep your viral load low and your CD4 cell count high. HIV medicine can make the viral load very low (called viral suppression ). Viral suppression is defined as having less than 200 copies of HIV per milliliter of blood.
What happens if you skip your medication?

Diagnostic Considerations
HIV infection can be diagnosed by HIV 1/2 Ag/Ab combination immunoassays. All FDA-cleared HIV tests are highly sensitive and specific. Available serologic tests can detect all known subtypes of HIV-1. The majority also detect HIV-2 and uncommon variants of HIV-1 (e.g., group O and group N).
Acute HIV Infection
Providers serving persons at risk for STIs are in a position to diagnose HIV infection during its acute phase.
Treatment
ART should be initiated as soon as possible for all persons with HIV infection regardless of CD4+ T-cell count, both for individual health and to prevent HIV transmission ( https://clinicalinfo.hiv.gov/en/guidelines/adult-and-adolescent-arv/whats-new-guidelines external icon ).
Other HIV Management Considerations
Behavioral and psychosocial services are integral to caring for persons with HIV infection. Providers should expect persons to be distressed when first informed that they have HIV.
STI Screening of Persons with HIV Infection in HIV Care Settings
At the initial HIV care visit, providers should screen all sexually active persons for syphilis, gonorrhea, and chlamydia, and perform screening for these infections at least annually during the course of HIV care ( 425 ). Specific testing includes syphilis serology and NAAT for N. gonorrhoeae and C. trachomatis at the anatomic site of exposure.
Partner Services and Reporting
Partner notification is a key component in the evaluation of persons with HIV infection. Early diagnosis and treatment of HIV among all potentially exposed sexual and injecting drug sharing partners can improve their health and reduce new infections.
Special Considerations
All pregnant women should be tested for HIV during the first prenatal visit.
