신형 코로나 바이러스에 감염되었는지 판단하는 방법?
Medico 바이러스 샘플링 키트를 사용하여 새로운 코로나바이러스 샘플을 얻습니다..
바이러스의 특징은 크기가 매우 작다는 것, 일반 광학현미경으로는 보이지 않음, 육안으로 직접 관찰하는 것은 불가능합니다. 하지만 각 바이러스는 고유한 유전적 서열을 가지고 있습니다.. By detecting the viral nucleic acid in the patient, it can be judged whether there is a virus in the patient.
Most of the current viral nucleic acid detection kits use the fluorescent quantitative PCR method. The detection principle is to use the unique gene sequence of the virus as the detection target. Through PCR amplification, the target DNA sequence we choose increases exponentially. Each amplified DNA sequence can be labeled with a fluorescent label that we added in advance. The probe binds to produce a fluorescent signal. The more target genes amplified, the stronger the accumulated fluorescent signal. In samples without virus, since there is no target gene amplification, no increase in fluorescence signal can be detected. 그러므로, nucleic acid detection is actually to determine whether there is viral nucleic acid in the sample by detecting the accumulation of fluorescent signals.
