case_images: HBV DNA levels (log10 IU/mL, cobas  HBV test) are displayed from July 2018 to April 2024.. The upper limit of quantitation of the assay is >170,000,000 IU/mL or >8.23 log10 IU/mL (denoted by the gray dashed line, ">LOQ"). HBV AVDR testing was performed for four samples, with the prevalence of mutations A317S and V191I per sample noted in orange (%). AVDR, antiviral drug resistance; HBV, hepatitis B virus; HBsAg, hepatitis B surface antigen.

case_images: Her ALT levels normalized, and her viral load improved significantly but plateaued (Fig. 1). Due to clinical suspicion of possible tenofovir resistance, additional HBV AVDR testing was requested (Fig. 1). Due to the inability to suppress the viral load on tenofovir (Fig. 1), HBV AVDR testing was requested based on the patient's most recent viral load (September 2023).
