Bangladesh scientists have developed a $3 COVID-19 testing kit

Bangladesh scientists have developed a $3 COVID-19 testing kit, which they claim can detect the virus in less than 15 minutes. The dot blot kit has been cleared for mass production in hopes to ease the pressure on the pathology services.


However, such kits look for antibodies produced by the white blood cells in response to the virus rather than the virus itself, there is a margin of error where it could return a false negative if used at the wrong time.
