Frontier port hepatitis C virus fluorescence RT-PCR detection method1 ScopeThis standard specifies the subject of hepatitis C virus fluorescent RT-PCR detection at the border port, the collection, transportation and preservation of specimens, and the detection process. Preface and results report. This standard applies to the laboratory testing of hepatitis C virus in entry and exit personnel at border ports.2 Normative referencesThe following documents are indispensable for the application of this document.

Note. It is mainly caused by blood, sexual life, vertical transmission of mother and baby, causing hepatitis C virus, in which blood transmission is the main mode of transmission of hepatitis C virus. Type C Hepatitis is a global epidemic that can lead to chronic inflammation, necrosis and fibrosis in the liver. Some patients can develop cirrhosis or even hepatocellular carcinoma. Clinically acute Hepatitis C manifests as elevated alanine aminotransferase, nausea, loss of appetite, yellow urine, yellow eyes and other symptoms. Chronic hepatitis C is characterized by fatigue, poor appetite, and abdomen. Bulging and so on. 3.2 Fluorescence RT-PCR real-timefluorescence RT-PCR On the basis of conventional RT-PCR, a specific fluorescent probe is added, which is an oligonucleotide labeled with one on each side. A fluorescent reporter group and a fluorescent quenching group. When the probe is intact, the fluorescent signal emitted by the reporter group is absorbed by the quenching group, PCR During amplification, the probe is hydrolyzed by the 5'-3' exonuclease activity of the Taq enzyme to separate the fluorescent reporter group from the fluorescence quenching group. The fluorescence monitoring system can receive fluorescent signals. Every time a PCR cycle is passed, the fluorescent signal is the same as the target segment, and there is a synchronization. In the process of exponential growth, the intensity of the signal is proportional to the nucleic acid content of the test object, and the content of the test object can be calculated according to the mathematical model. 3.3 Ct value cyclethreshold In the fluorescence RT-PCR amplification process, the value of the fluorescent signal within the range of the exponential growth region is called the threshold (threshold). The number of amplification cycles elapsed when the fluorescent signal of the product increases to a set threshold is referred to as the Ct value. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of SN/T 4612-2016_English be delivered?Answer: Upon your order, we will start to translate SN/T 4612-2016_English as soon as possible, and keep you informed of the progress.
