不論是做人工或試管，或是單純的驗孕，我們大多會用抽血驗所謂的懷孕指數 (beta hCG)。 為什麼要抽血驗beta hCG呢？ 有幾個優點: 1、比較精確：驗尿有比較高的比例會有偽陽性或偽陰性，而其中...

β-HCG检测：采用更为先进的 荧光免疫层析技术，它利用荧光标记的抗体与指尖血中的β-HCG特异性结合，然后通过专门的仪器检测荧光信号的强度，从而得出β-HCG的 具体定量数值。

An hCG level of less than 5 mIU/mL is considered negative for pregnancy, and anything above 25 mIU/mL is considered positive for pregnancy. An hCG level between 6 and 24 mIU/mL is considered a grey area, and you’ll likely need to be retested to see if …

β-HCG是目前国际公认的在滋养细胞肿瘤中应用最广、最重要的肿瘤标记物，能反映滋养细胞数量和功能的状态。 β-HCG的消退规律对滋养细胞疾病预测和预后极为重要，葡萄胎患者的β-HCG在清宫术后应稳定下降。

血β-HCG检查是指通过检测血清中的β-HCG水平，为高危妊娠人群的早期筛查及病理妊娠、滋养细胞肿瘤和染色体三体综合征的诊断、鉴别诊断及判断预后提供临床依据。
