The Real-Time Fluorescence Quantitative PCR Instrument has automatic integration, simple operation, fast detection speed, high sensitivity and other advantages. The gold standard for COVID-19 diagnosis is a demonstration of SARS-CoV-2 detection in patients' respiratory secretions using real-time reverse transcriptase-polymerase chain reaction (RT-PCR).
Nucleic Acid Detection (NAT) or Nucleic Acid Amplification Trials (NAAT), one of the nucleic acid based detection methods, is a technique used to detect nucleic acids, a specific virus or bacteria that acts as a pathogen in blood, tissue, urine, etc., and the NAT system differs from other tests in that it detects genetic substances rather than antigens or antibodies.
Nucleic acid techniques can amplify template molecules millions of times for high sensitivity detection. It is one of the most valuable analysis methods, widely used in infectious diseases diagnosis, food safety guarantee and many other testing fields.
