Afterwards, the liquid sample is removed with a transfer pipette to pass it into the chamber and when the layer is closed, the PCR reaction starts automatically. After 30 minutes the test result is obtained and, in this sense, there are three possibilities, positive for covid-19, negative or invalid (here it would be necessary to repeat the process).
To carry out this process, a specialist in molecular biology is not required and, Rodríguez points out, anyone can apply it, but other elements must be taken into account, such as the circulation of air in the space, the number of people who travel and how much time they are there.
What to do after getting the result?
Thermo Fisher invited Expansión to a test at its Customer Experience Center, in which the device collected air for three hours in a 200-square-meter space.
Although the test that was taken was negative, the expert points out that in the event of a positive, one must remain calm and not assume that everyone in the room is sick, because this type of test, even if the viral load is low, detects the virus.
Given this result, it recommends that the people who make up the group take proactive actions, such as isolating themselves and being alert to possible symptoms to avoid outbreaks before the virus can spread.
