Drug resistance testing requires taking a sample of your blood. There are two kinds of tests: Genotype testing. These find drug resistance mutations in the genes of HIV. These tests look at the ...

HIV drug susceptibility tests can evaluate either the genotype or phenotype of the predominant viral quasispecies. The HIV genotype refers to the actual DNA sequence of the virus; the phenotype ...

During the maintenance, the State Grid Zhejiang Taizhou Power Supply Company assigned key tasks to the young staff members of ...

Shorted-circuit test (the secondary winding is shorted, so the LRC meter only measures the primary leakage inductance (L1l) But, the technical problem is that the wire we use to short circuit the ...

HIV drug resistance testing has been considered an emerging asset to modernized HIV management. Despite the increased number of antiretroviral agents currently available, virologic failure remains ...
