乙型肝炎測試（表面抗原及抗體 HBsAg & HBsAb）
type: Product
description: 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。
