Comparison of particle-enhanced turbidimetric inhibition immunoassay and fluorescence polarization immunoassay using monoclonal antibodies for theophylline.

abstract：:Infection with drug-resistant HIV-1 may result from the acquisition of mutant strains or from their selection within the individual; either can compromise the efficacy of antiretroviral therapy (ART). Drug-resistance testing is recommended to assist in the choice of ART. Herein, factors that contribute to the selectio...
