本文評述了新近發展起來的以大規模集成流路(IFC)芯片為基礎的數字 PCR 技術。指出 PCR 已被證明可用于除外傷和營養不良癥以外所有其他疾病的分子診斷。但是傳統 PCR 技術有誤診率高的缺點,即便采用傳統的數字 PCR 技術,也還會有 2% 以上的差錯率。但是當采用 IFC 芯片作數字 PCR 檢測時,將可使測量準確度達到 99.75% 以上,并可做絕對測量,因而在各種疾病早期分子診斷方面具有其他方法無法比擬的巨大潛力。
A Very Promising New Analytical and Diagnostic Technology: Large Scale Integrated Fluidic Circuit-PCR
Abstract The newly developed digital polymerase chain reaction(dPCR) technology based on integrated fluidic circuit(IFC) chip is critically reviewed. As was shown that other than injury and dystrophy all the diseases could be di-agnosed with the use of PCR technology. However, the misdiagnosis rate of traditional PCR technology is quite high. An error rate as high as >2% is common even though a traditional digital PCR is used. However, when a digital PCR based on IFC chip is used an accuracy of 99.75% is attainable and even an absolutely quantitative determination is also possible. Therefore, the digital PCR based on IFC chip is a very promising technology for the early molecular diagnosis of various diseases.
