Cómo juzgar si estás infectado con el nuevo coronavirus?

By using Medico virus sampling kits get the new coronavirus sampels.

The characteristic of the virus is that it is very small, invisible under ordinary optical microscope, and it is impossible to observe directly with the naked eye. But each virus has its own unique genetic sequence. 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. Por lo tanto, nucleic acid detection is actually to determine whether there is viral nucleic acid in the sample by detecting the accumulation of fluorescent signals.
