Medico 제조업체의 핵산 검출 원리 소개
We need scientific methods to diagnose or rule out whether a patient is infected with the new coronavirus.
현재 구체적이고 권위 있는 진단 테스트 방법이 있습니다., 그리고 오직 하나뿐이다: 핵산 검사.
1. Principles of conventional nucleic acid detection
Direction: 유전학 방법: RT-PCR Reverse transcription polymerase chain reaction Test object: Virus gene itself Accuracy: Maximum time: a few hours to a few days Advantages: High accuracy, is the only basis for diagnosis at present Disadvantages: Long time, High barriers to professional operation
The new coronavirus is an RNA virus that can replicate itself when it enters and infects the human body. As long as the person is infected, there must be a virus in the body. But because the virus is too small to be seen under the microscope, it cannot be confirmed directly by observation.

Throat swab sample collection.
Everyone should be familiar with the term “인후 면봉”, which is the primary source of samples for new coronavirus testing. 간단히 말해서, it is to use a plastic stick to reach the patient’s throat and wipe it, collect some respiratory fluid, then package it, refrigerate, and send it to the laboratory for RT-PCR testing.
하지만, experts soon discovered that the results of the throat swab samples were inaccurate and the probability of false negatives was high. 그러므로, in different countries or regions, front-line medical workers may also collect samples such as nasal swabs, 담, and feces for testing.
