Drug-resistance testing identifies which, if any, HIV medicines won’t be effective against your specific strain of HIV. Drug-resistance testing results help determine which HIV medicines to include in an HIV treatment regimen. Taking your HIV medicine as prescribed helps prevent drug resistance.
What is an HIV treatment regimen?
· An HIV treatment regimen is a combination of HIV medicines used to treat HIV infection. HIV treatment (also called antiretroviral therapy or ART) begins with choosing a regimen.

Providers should use a laboratory-based antigen/antibody (Ag/Ab) combination assay as the first test for HIV, unless persons are unlikely to follow up with a provider to receive their HIV test results; in those cases screening with a rapid POC test can be useful. Preliminary positive screening tests for HIV should be followed by supplemental ...

This is called treatment as prevention.
What is drug resistance in HIV?
What Is HIV Drug Resistance? Drug resistance can be a cause of treatment failure for people living with HIV. As HIV multiplies in the body, it sometimes mutates (changes form) and produces variations of itself.

How to diagnose HIV?
Diagnosis. HIV can be diagnosed through blood or saliva testing. Available tests include: Antigen/antibody tests. These tests usually involve drawing blood from a vein.

What is a blip in HIV?
Patients may experience a temporary increase or “blip” in their viral load, defined as viral loads transiently detectable at low levels. These blips usually go back down by the next viral load test. Patients who are using viral suppression as their primary prevention method and experience a blip may benefit from using other prevention strategies until their viral load is undetectable again. These prevention strategies could include condoms and pre-exposure prophylaxis (PrEP) for HIV-negative partners.
How to diagnose HIV?
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).
What test is used to test for HIV?
According to an algorithm for HIV diagnosis, CDC recommends that HIV testing begin with a laboratory-based HIV-1/HIV-2 Ag/Ab combination assay, which, if repeatedly reactive, is followed by a laboratory-based assay with a supplemental HIV-1/HIV-2 antibody differentiation assay ( https://stacks.cdc.gov/view/cdc/50872 ). This algorithm confers an additional advantage because it can detect HIV-2 antibodies after the initial immunoassay. Although HIV-2 is uncommon in the United States, accurate identification is vital because monitoring and therapy for HIV-2 differs from that for HIV-1 ( 420 ). RNA testing should be performed on all specimens with reactive immunoassay but negative supplemental antibody test results to determine whether the discordance represents acute HIV infection.
What is a sexual health clinic?
STD specialty or sexual health clinics are a vital partner in reducing HIV infections in the United States. These clinics provide safety net services to vulnerable populations in need of HIV prevention services who are not served by the health care system and HIV partner service organizations. Diagnosis of an STI is a biomarker for HIV acquisition, especially among persons with primary or secondary syphilis or, among MSM, rectal gonorrhea or chlamydia ( 197 ). STD clinics perform only approximately 20% of all federally funded HIV tests nationally but identify approximately 30% of all new infections ( 414 ). Among testing venues, STD clinics are high performing in terms of linkage to HIV care within 90 days of diagnosis; during 2013–2017, the percentage of persons with a new diagnosis in an STD clinic and linked to care within 90 days increased from 55% to >90% ( 415, 415 ).
What are the challenges of HIV?
They face multiple adaptive challenges, including coping with the reactions of others to a stigmatizing illness, developing and adopting strategies to maintain physical and emotional health, initiating changes in behavior to prevent HIV transmission to others, and reducing the risk for acquiring additional STIs.

When should a woman be tested for HIV?
All pregnant women should be tested for HIV during the first prenatal visit. A second test during the third trimester, preferably at <36 weeks’ gestation, should be considered and is recommended for women who are at high risk for acquiring HIV, women who receive health care in jurisdictions with high rates of HIV infection, and women served in clinical settings in which prenatal screening identifies ≥1 pregnant woman with HIV per 1,000 women screened ( 138 ). Diagnostic algorithms for HIV for pregnant women do not differ from those for nonpregnant women (see STI Detection Among Special Populations). Pregnant women should be informed that HIV testing will be performed as part of the routine panel of prenatal tests ( 138 ); for women who decline HIV testing, providers should address concerns that pose obstacles, discuss the benefits of testing (e.g., early HIV detection, treatment, and care for improving health of the mother and reducing perinatal transmission of HIV), and encourage testing at subsequent prenatal visits. Women who decline testing because they have had a previous negative HIV test result should be informed about the importance of retesting during each pregnancy. Women with no prenatal care should be tested for HIV at the time of delivery.
When should HIV testing be performed?
Testing for HIV should be performed at the time of STI diagnosis and treatment if not performed at the initial STI evaluation and screening ( 82, 195, 416 ).
What is the first test for HIV?

How does HIV affect a mother?
It reduces the risk of mother-to-child transmission from pregnancy, labor, and delivery. If a woman living with HIV can take HIV medication as prescribed throughout pregnancy, labor, and delivery and if HIV medication is given to her baby for 4-6 weeks after delivery, the risk of transmission from pregnancy, labor, and delivery can be reduced to 1% or less. Scientists don’t know if a woman living with HIV who has her HIV under control can transmit HIV to her baby through breastfeeding. While it isn’t known if or how much being undetectable or virally suppressed prevents some ways that HIV is transmitted, it is reasonable to assume that it provides some risk reduction.

Why is it important to take your medicine as prescribed?
It also prevents you from spreading it to your HIV-negative partners. Skipping doses could lead to drug resistance. That means the virus gets used to the drug and it no longer works as well. This is why it is important to take your medicine as prescribed.
Can you change the doses of STRs?
One problem with STRs is that your doctor can’t change the doses of each individual drug.
Is Juluca good for HIV?
The FDA recently approved two new pills that have two drugs instead of three. This could be good for people with HIV because taking fewer drugs means less exposure to possible long-term effects. One is called Juluca. It ’s only for people on maintenance, or ongoing, therapy.
What is the treatment for HIV?
It’s called antiretroviral therapy (ART). The drugs help keep your body’s virus count, called an HIV “viral load,” low or “undetectable.” That in turn lets your immune system heal itself and stay strong. It also lowers the odds that you might spread HIV to other people.

HIV attacks these cells, and makes it easier for you to pick up infections and get sick. Your doctor will check your CD4 count every 3-6 months if it’s in the low range (less than 500 cells per cubic millimeter of blood).
