Methods Anti HGV, HBsAg, anti HBs, anti HBc and anti HCV were detected by enzyme linked immunoassys (EIA). Anti HGV positive sera were further tested for HGV RNA by a nested reverse transcription polymerase chain reaction (RT nPCR).

• 方法应用酶联免疫法（EIA）检测抗?HGV、HBsAg、抗?HBs、抗?HBc及抗?HCV，并对抗?HGV阳性者进一步用逆转录套式PCR（RT?nPCR）法检测HGVRNA。
