COVIDPCR检查的意思是聚合酶链式反应,能够用来扩增DNA。将少量DNA扩增到可以检测到的程度,有些病毒的核酸是DNA,需要用这种方法来检测,因此PCR不是一种测试,而是一种检测DNA的方法。例如乙肝病毒DNA定量,就是这样使用,DNA检测的目的一方面是诊断疾病,若连病原体的DNA都能被检测到,那就意味着感染了这种病原体。 pc...
目前, 大部分的COVID-19測試都是基因檢測, 即PCR檢測 These tests are very accurate because ever if there's only a tiny amount of virus present in a patient sample . 此檢測非常準確, 因為即使患者樣本中只有少量病毒 PCR - which stands for polymerase chain reaction - is able to take genetic mat...
