As COVID-19 is spreading around the world, people are trying their best to stop the spreading of COVID-19. For screening out who is infected with the COVID-19 virus, and separate them from those healthy ones, COVID-19 detection is very important. By nucleic acid testing, we can accurately know who is infected with COVID-19 virus. Nevertheless, nucleic acid testing spending more time and professional medical resources are limited in many places. For preliminary detection of COVID-19, people of many places choose to apply COVID-19 antigen test kit.
How accurate is the antigen test?
Actually, COVID-19 antigen test is not as accurate as nucleic acid testing.
COVID-19 Antigen tests may not be detectable when an individual is newly infected, but nucleic acid tests have a high probability of detecting COVID-19 virus.
Overall, the incubation period and the initial period
The positive detection rate of antigen test is significantly lower than that of nucleic acid test,
What factors will influent the accuracy of antigen test?
The accuracy of antigen tests depends on a number of factors:
·Product quality
·Sampling accuracy
If the sampling operation is not strictly in accordance with the instructions, it will have a great influence on the test results.
Accuracy of Singclean COVID-19 Test Kit (Nasal Swab)
Singclean COVID-19 Antigen Test Kit
The results of the COVID-19 Test Kit（Colloidal Gold Method) were compared to results of RT-PCR assays for SARS-CoV-2 in nasal swab specimens. A total of 499 nasal cavity specimens were tested in this study. The COVID-19 clinical specimens contain specimens from individuals with symptoms within 7 days. The results of test reagent and control reagent both were 350 negative specimens and 149 positive specimens. The sensitivity and specificity calculated were valid in this study.
In short, COVID-19 antigen test provides only a preliminary test result. Therefore, any reactive specimen with the COVID-19 Test Kit must be confirmed with alternative testing method(s)and clinical findings.
