HBcrAg and HBV-DNA patterns in seroconversion panels. The data on HBsAg, HBeAg, and anti-HBs, anti-HBe, and anti-HBc antibodies were obtained from the supplier's data sheet. Closed symbols, positive; open symbols, under the cutoff. (A) BBI PHM935B panel. ▪ and □ HBcrAg [log(units/milliliter)]; ⧫ and ◊, HBV-DNA detected by the Roche Amplicor HBV Monitor test (detection limit, 4 × 10² to 4 × 10⁷ copies/ml); ▴ and ▵, in-house RTD-PCR (detection limit 20 copies/ml). (B) BCP HBV6281 panel. ▪ and □, HBcrAg [log (units/milliliter)]; ⧫ and ◊, HBV-DNA detected by BCP PCR (detection limit, 10² copies/ml).
