Ten-Minute Coronavirus Test for $1
From their website [0] my guess is their test is ELISA [1] based or similar method of detecting if the human body has had an immune reaction to the virus in the amount that is detectable. Where as the more expensive test is PCR based [2] that requires the heating-cooling cycles and machines to do it.<p>The PCR-based test basically take the RNA of the virus converts it to DNA and then doubles the amount of DNA every heating cycle. Assuming we are talking about real-time PCR the PCR cycle of double is what takes time.<p>I have not seen the data on the incubation period and the immune response, to know if these immune detection tests will be able to provide early detection for asymptomatic case . It&#x27;s probably for symptomatic cases and wanted to ensure it&#x27;s not flu or another infection and it&#x27;s COVID-19. This is not to say the test is useless. It actually great inexpensive way of testing the population with symptoms and using more expensive and timely test for early detection. Reducing the overall burden.<p>worth mentioning are other initiatives that are focusing on cheaper and faster PCR process (though with potential of higher false negative and positive results) [3]<p>[0]<a href="https:&#x2F;&#x2F;mologic.co.uk" rel="nofollow">https:&#x2F;&#x2F;mologic.co.uk</a><p>[1]<a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;ELISA" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;ELISA</a><p>[2] <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Real-time_polymerase_chain_reaction" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Real-time_polymerase_chain_rea...</a><p>[3] <a href="https:&#x2F;&#x2F;twitter.com&#x2F;JMRothberg&#x2F;status&#x2F;1238115465467133959" rel="nofollow">https:&#x2F;&#x2F;twitter.com&#x2F;JMRothberg&#x2F;status&#x2F;1238115465467133959</a>
