Новый тест на коронавирус: взятие мазков из носа или полости рта

На февраль 5, 2020, Главное управление Национальной комиссии здравоохранения официально выпустило Уведомление о распечатке и распространении плана диагностики и лечения пневмонии, вызванной новым коронавирусом. (Пробный 5), в котором упоминалось, что новая нуклеиновая кислота коронавируса может быть обнаружена в мазке из носоглотки., мокрота, секреция нижних дыхательных путей, кровь, фекалии и другие образцы. So how to sample nasal swab or oral swab correctly?

1. Sampling method of throat swab: The accuracy of throat swab detection is relatively high. This detection method mainly detects the bacteria in the throat of patients. If the test result is positive, it means that they are infected with virus. When the human body is in a healthy condition, there are many normal oral flora in the throat, which will not contain pathogenic bacteria. If the immunity of the human body declines, the pathogenic bacteria will lead to human infection. At this time, collecting the bacteria in the throat of the patient can determine the health status of the patient. Of course, there may be false negatives, which are mainly caused by fewer bacteria in the oral cavity at the early stage of infection, or because pathogenic bacteria have invaded the lower respiratory tract. In order to ensure the accuracy of detection, blood tests can be taken.(рекомендуемые)
