Covid-19 detection method and instrument

Viral nucleic acid detection

At present, of the 10 new coronavirus nucleic acid detection reagents that have been approved, 8 use the fluorescent PCR method, and the remaining detection methods are the combined probe-anchored polymerization sequencing method and the constant temperature amplification chip method.

Fluorescence PCR detection of covid-19 requires a nucleic acid extractor and centrifuge to obtain patient samples, and then use real-time PCR for detection

Ningbo SCIENTZ produces high-quality nucleic acid extractors, centrifuges, and PCR machines, all of which are instruments used to detect COVID-19. These instruments are exported to the United States, India, Europe and other countries .

PCR method refers to the polymerase chain reaction, which can greatly increase the trace amount of DNA. When used to detect the new coronavirus, because the new coronavirus is an RNA virus, it is necessary to reverse transcribe the viral RNA into DNA before performing PCR detection.

The principle of fluorescent PCR detection is that as the PCR proceeds, the reaction products continue to accumulate, and the fluorescence signal intensity also increases in proportion. Finally, the change in the amount of the product is monitored by the change in the fluorescence intensity, thereby obtaining a fluorescence amplification curve.

This is currently the most commonly used method for nucleic acid detection of the new coronavirus.
