荧光定量PCR(fluorescencequantitativepolymerasechainreaction,FQ-PCR)是新研制出的一种核酸定量技术。该技术在PCR反应系统中引入了荧光标记探针,具有高灵敏性、高特异性和高准确性的特点。目前已被初步应用于鼻咽癌诊断、临床疗效判断、肿瘤复发及转移监测等多个方面。 Fluorescence quantitative PCR (FQ-PCR) is a newly developed nucleic acid quantification technique. The technology introduces a fluorescently labeled probe into the PCR reaction system for high sensitivity, specificity and accuracy. Has been initially applied to the diagnosis of nasopharyngeal carcinoma, clinical judgment, tumor recurrence and metastasis monitoring and other aspects.
