可以在醫生的診所裡抽血。

血檢由三種常見的檢測組成。

有時，醫生可能要求在您初診後6個月再次檢查您的血液，以確認您的B型肝炎狀態。

如果您認為您最近已感染B型肝炎，可能需要長達9週的時間才能在您的血液中檢測到病毒。

您的B型肝炎驗血結果可能令人困惑，您想要確定您的診斷——您是感染了B型肝炎，還是已經從B型肝炎感染痊癒，或是您患有慢性B型肝炎？ 此外，索取一份驗血報告副本會很有幫助，這樣您便可以充分瞭解哪些檢查結果呈陽性，哪些呈陰性。

「B型肝炎血檢」是由哪三種檢測組成的？B型肝炎血檢只需要採集一個血樣，但包括三種必要的檢測來做出最後診斷： HBsAg（B型肝炎表面抗原）  HBsAb或anti-HBs（B型肝炎表面抗體）  HBcAb或anti-HBc（B型肝炎核心抗體） 什麼是B型肝炎表面抗原(HBsAg)？「陽性」或「反應性」HBsAg檢測結果表示此人已感染B型肝炎病毒，可能是「急性」或「慢性」感染。

受感染者可以經由血液將病毒傳給他人。

B型肝炎表面抗體（HBsAb或anti-HBs）什麼是？「陽性」或「反應性」HBsAb（或anti-HBs）檢測結果表明，一個人要麼成功地對B型肝炎疫苗有反應，要麼已經從急性B型肝炎感染痊癒。

這個結果（加上陰性HBsAg結果）表示您對未來的B型肝炎感染是免疫的（免患B型肝炎感染）。

什麼是B型肝炎核心抗體(HBcAb)？HBcAb是一種抗體，是病毒的一部分——它不提供保護。

「陽性」或「反應性」HBcAb（或anti-HBc）檢測結果表明過去或現在的感染。

這種檢測結果的解釋視其他兩種檢測結果而定。

它與保護性表面抗體（陽性HBsAb或anti-HBs）共同出現表明先前的感染和痊癒。

對於慢性感染者，它會通常與病毒（陽性HBsAg）一起出現。
