Drug Resistance Testing from Dried Blood Spots

Genotyping of HIV to test for nucleoside reverse transcriptase inhibitors (nRTI) or non-nucleoside reverse transcriptase inhibitors (NNRTI) resistance mutations from dried blood spots (DBS)

Drug resistance testing is recommended among persons initiating combined antiretroviral therapy (cART) and in maintaining a successful cART regimen. DBS allow for ease of collection of specimens for drug resistance testing in a variety of settings both domestically and internationally.
