One participant who wanted to return to work was staying at home as she had a cough and – confusing the antibody with the antigen test - said a positive test would help to distinguish between a normal cold and the COVID virus. She argued that a test would enable people to remain in...
Add 2 drops (about 60μl) of sample solution extract to the sample well of the test cassette. Observe the results showed within 10-15 minutes, and the results showed after 15 minutes have no clinical significance. 【INTERPRETATION OF RESULTS】 Negative: Only a red line appears in the qualit...
Although COVID-19 at-home test kits provide results within 30 minutes, they test for viral antigens, ie, they are less sensitive (ie, have more false negatives) than PCR (polymerase chain reaction) tests,4 which have an estimated clinical sensitivity of approximately 70%.5,6 Therefore, user...
The test results are positive and need further confirmation. Negative results can not exclude the possibility of infection. 【Main components】 1.2019-nCoV IgM/IgG detection card (T1 line coated with mouse anti human IgG (γ) monoclonal antibody, T2 line wrapped by mouse anti human IgM (μ) m...
A COVID-19 diagnosis via polymerase chain reaction, antigen test, or serologic confirmation was required for inclusion in the study. We used the earliest specimen collection, test, or result date as the COVID-19 diagnosis date. The COVID-19 diagnosis dates ranged from January 1 to December ...
All patients were confirmed SARS-CoV-2 positive by either a polymerase chain reaction (PCR) or antigen test. Based on the COVID-19 severity categorization parameters [21,22], 9.1% of patients had mild cases, 30.2% had severe cases, and 59.6% were listed as critical. Table 1. Clinical ...

Analysis was performed using a middleware software referred to as FlowG (LabHelp Labautomation), which can be used for interpretation of the results and communicating them back to the laboratory information system (LIS). Samples with a cycle time value (Ct) lower than 34 were considered as pos...
