The present invention provides a method of detecting a heteroresistant population of a pathogen in a sample, the method comprising: a) providing a sample comprising a population of a pathogen; b) extracting nucleic acids from the sample; c) amplifying a target locus of the genome of the pathogen in the extracted nucleic acids, wherein the target locus comprises at least one minor variant associated with drug resistance in the pathogen; d) consecutively sequencing both overlapping nucleic acid strands from a single DNA molecule amplified from the target locus on a Next Generation Sequencing (NGS) platform; e) applying an alignment algorithm to sequencing data from the overlapping nucleic acid strands; and f) performing an analysis of the aligned sequencing data to detect the at least one minor variant and heteroresistant population of the pathogen.
