Easysweet COVID-19 Test Kit is a new method for detecting the new coronavirus. The method is simpler to use. Can antigen detection replace nucleic acid detection? Antigen detection has a certain proportion of false positives and false negatives when it is used. Relatively It is not so "rigorous" for nucleic acid testing, so it cannot replace accounting testing as a diagnostic standard. In addition, in terms of accuracy of antigen detection and nucleic acid detection, nucleic acid detection is still higher.
1. Can the Easysweet COVID-19 Test Kit replace nucleic acid detection?
Compared with nucleic acid testing, antigen testing does not require professional machines and special places, and results can be obtained in a shorter time. However, antigen testing cannot replace nucleic acid testing as a "diagnostic" standard.
The sensitivity of the approved Easysweet COVID-19 Test Kit is 90.91%, and the specificity is 100%. Generally speaking, there is a certain proportion of false positives and false negatives. Therefore, at present, antigen detection cannot replace nucleic acid detection as the standard for diagnosis.
In addition, according to the characteristics of antigen testing, in areas with low prevalence of SARS-CoV-2, it is not recommended for the general population to do SARS-CoV-2 antigen testing if there are no symptoms and no relevant epidemiological travel history.
2. Which is more accurate, Easysweet COVID-19 Test Kit or nucleic acid detection
Nucleic acid testing will be more accurate.
The accuracy of nucleic acid detection and antigen detection is affected by many factors. For the current detection method, when the Ct value is less than 25, the consistency between nucleic acid detection and antigen detection is about 95.8%; when the Ct value is higher than 25, the consistency is about 50.7%; when the Ct value is higher than 30, the consistency is only 20.9%. Therefore, the false-negative rate of antigen test results is high, however, it is possible to find infected persons with higher viral loads, or more infectious agents.
Studies have shown that in the process of in vitro infection with the new coronavirus, the virus replication will reach its peak within 24 hours. It is speculated that after the human body is infected with the new coronavirus, the lower limit of the antigen detection will be reached within 24 to 48 hours. If the antigen detection result is Negative, but the nucleic acid test is positive, it may be that the Ct value is greater than 30, indicating that the viral load has dropped and the infectivity has been greatly reduced.
Therefore, the extensive and active use of the Easysweet COVID-19 Test Kit can detect infected people with mild or asymptomatic symptoms. These people, who take timely isolation measures, will help reduce the spread of the virus in families and communities. It is more suitable for large-scale use in communities, airports, and dense places. Easysweet COVID-19 test kit wholesale at cheap prices. Let Easysweet help you achieve business success.
