Drug-Resistance Testing | NIH - Clinicalinfo
HIV drug-resistance testing is recommended at entry into care for people with HIV to guide the selection of the initial antiretroviral (ARV) regimen (AII). If antiretroviral therapy (ART) is deferred, repeat testing may be considered at the time of ART initiation (CIII).

Aug 4, 2021 · Drug-resistance testing identifies which, if any, HIV medicines that will not be effective against a person’s HIV. Drug-resistance testing is done using a sample of blood. People with HIV should start taking HIV medicines as soon as possible after their HIV is diagnosed.
HIV Drug Resistance Testing - Stanford Health Care
HIV drug resistance testing determines whether a patient with HIV has a mutated form of the virus that does not respond to antiretroviral therapy (ART).
Interpretation of HIV-1 drug resistance testing - UpToDate
Sep 17, 2024 · Managing patients with human immunodeficiency virus (HIV) drug resistance has become less common. Advances in drug development have allowed for more potent antiretroviral therapy (ART) regimens that are easier to take, resulting in fewer persons who develop drug-resistant strains of HIV [1].
HIV Resistance Assays - NCBI Bookshelf - National Center for ...
HIV resistance testing is generally accomplished through genotyping, which directly sequences the HIV genome to detect mutations. Phenotyping, which measures HIV replication in the presence of drug, may also be available, but genotyping is generally preferred.
Resistance testing: genotype | Johns Hopkins HIV Guide
Oct 10, 2021 · HIV gene sequencing assays detect mutations that confer ARV drug resistance. Reverse transcriptase and protease gene mutations confer NRTI, NNRTI, and PI resistance. Integrase gene mutations confer integrase inhibitor (INSTI) resistance. gp41 (envelope) gene mutations confer fusion inhibitor (enfuvirtide) resistance.
Overview of HIV-1 drug resistance testing assays - UpToDate
This topic will provide an overview of HIV drug resistance testing. The interpretation of these tests and the approach to selecting an antiretroviral therapy (ART) regimen for patients with drug resistance mutations are discussed elsewhere.
Resistance Testing - Clinicalinfo
Resistance testing is done using a sample of blood. There are two types of resistance testing: genotypic and phenotypic. Resistance testing is used to guide selection of an HIV regimen when initiating or changing antiretroviral therapy (ART).
HIV Resistance Testing – International Association of ... - IAPAC
WHAT IS HIV DRUG RESISTANCE TESTING? HIV drug resistance testing is used to help select a drug regimen that will likely be effective in treating your HIV infection. The test is used to determine whether the HIV strain infecting you is resistant to one or more ARVs.
HIV Resistance test - HIV - Veterans Affairs
Oct 17, 2019 · This test determines whether the particular virus in your body is resistant to HIV medications. HIV reproduces rapidly and, as the virus makes copies of itself, small changes (or mutations) sometimes result.
