Nucleic acid testing air film usually refers to the presence of the word air film on a nucleic acid report, meaning that the testing of that nucleic acid sample was done in an air film type testing laboratory. In a conventional laboratory, the sample is extracted and sent to a specialized laboratory for testing. In contrast, an air-membrane laboratory has a specialized amplification chamber, and the sample can be tested directly in the amplification chamber after it is extracted. This type of laboratory not only increases efficiency, but also effectively reduces the chance of virus transmission during the transmission process. Gas film laboratories are much more efficient than conventional laboratories and are more suitable for use in more populated cities. Nucleic acid testing air film laboratories are produced for large-scale nucleic acid testing, greatly relieving the pressure of large sample sizes in various nucleic acid testing laboratories to ensure that nucleic acid testing can produce results in the shortest possible time.
