7677 病原学及血清学检查 Etiological and serological examination
7678 病原学检查：釆用RT-PCR或/和NGS方法在鼻咽拭子、痰和其他下呼吸道分泌物、血液、粪便等标本中可检测出新型 冠状病毒核酸。 Etiological examination: COVID-19 nucleic acids can be detected in nasopharyngeal swabs, sputum and other lower respiratory tract secretions, blood and feces by using RT-PCR and next generation sequencing technology (NGS).
7679 检测下呼吸道标本（痰或气道抽取物）更加准确。 It is more accurate to detect the lower respiratory tract specimen (sputum or airway extract).
7680 标本采集后尽快送检。 Once collected, specimen examination should be performed as soon as possible.
7681 血清学检查：新型冠状病毒特异性IgM抗体多在发病 3-5天后开始出现阳性， Serological examination: the COVID-19-specific IgM antibody starts to show positive after 3-5 days from onset.
7682 IgG抗体滴度恢复期较急性期有4倍及以上增高。 In comparison, the titer of COVID-19-specific IgG antibody is 4 times higher in recovery period than that in acute phase.
7683 胸部影像学 Chest imaging
7684 早期呈现多发小斑片影及间质改变，以肺外带明显。 At the early stage of the disease, multiple small patchy shadows and interstitial changes appear, which are more obvious in the periphery of the lung.
7685 进而发展为双肺多发磨玻璃影、浸润影， Then it developed into multiple ground-glass shadows and infiltrates shadows.
7686 严重者可出现肺实变，胸腔积液少见。 In severe cases, pulmonary consolidation may occur. Pleural effusion is rare.
