【Abstract】 In order to study the feasibility of gene chips technology in the detection of HBV mutation associated with lamivudine, we detected the mutation of HBV in peripheral blood of 30 patients treated with lamivudine for at least half a year by gene chips. The result was compared with that from direct sequencing. Both results are highly coincident. The rate reaches 100% while detecting single strain of virus infection, and 85% in multi-strains virus infection. Gene chip technology is quite valuable and practical in future clinic.更多还原
