Summary of urine DNA analysis by PCR assays targeting multiple locations in the HBV genome. The amount of DNA detected is indicated by patterned boxes as follows: empty box: below the limit of detection; light gray box: less than 100 copies/ml; dark gray box: 100–1000 copies/ml; black box: greater than 1000 copies/ml; box with a slash: Not available, the assay was not run. T: Total urine DNA, H: High molecular weight urine DNA fraction, L: low molecular weight urine DNA fraction
