Nucleic acid detection refers to viral nucleic acid detection, which is PCR detection and can be used for the diagnosis of infectious diseases such as new coronavirus, hepatitis B virus, and human immunodeficiency virus. PCR detection refers to the use of polymerase chain reaction technology to amplify the trace DNA fragments of pathogens such as viruses to the extent that they can be used for detection, which can effectively improve the accuracy of the inspection. Nucleic acid detection uses PCR detection technology, which can not only be used to diagnose diseases, but also can determine the amount of virus replication, which is conducive to evaluating the severity of the disease and the effect of treatment.
During nucleic acid detection, the saliva, intestinal fluid, blood, etc. of the subject need to be collected, and then the specimen is placed in the nucleic acid extraction kit. The virus preservation solution in it can maintain the activity of the pathogen and keep the pathogen DNA in the sample in an active state. Then, the DNA is amplified by PCR technology, and the subsequent detection is carried out. Generally, the corresponding results can be obtained after 1-4 hours, which has the advantages of high detection efficiency, high accuracy, and convenient operation.
