病毒的特徵是很小, 普通光學顯微鏡下看不見, 且無法用肉眼直接觀察. 但每種病毒都有其獨特的基因序列. 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. 所以, nucleic acid detection is actually to determine whether there is viral nucleic acid in the sample by detecting the accumulation of fluorescent signals.
