Scholars from United State They developed a A quick test of Covid-19 That allows you to send a file Results is yours prison cell. It is cheap, safe, accurate and takes only a few minutes to identify a sample.
It is a very sensitive and accurate rapid test run from battery to tester Coronavirus disease-19. It’s also practical because it doesn’t need to be applied in the laboratory, said Huimin Zhao, lead author of the study.
The team of researchers discovered a system that produces synthetic restriction enzymes. That is, the elements that allow specific genes to be recognized and identified in the genome of an organism. They called this Portable and Scalable Test (SPOT).
After being introduced into the body, the DNA clues are responsible for distinguishing the viral genes with a fluorescent dye after they are switched on. If it lights up, that’s a positive test Coronavirus disease-19.
Although it is still a prototype, they estimate these quick tests are $ 78, or around 1,500 MXN. The reagents are worth $ 7 (138 pesos) for the test. Even, due to certainty, it can be more reliable than PCR.
In addition, it is free of stitches and needles as the test is done from a sample of saliva after leaving a drop of saliva, using a 3D printer, the device can detect a viral particle in each drop, according to its creators.
Meanwhile, in clinical trials, scientists made 104 saliva samples, which gave 28 samples out of 30 positive, And 73 out of 74 were negative, according to this margin of error.
The result will be available in less than 30 minutes. Not only does the device allow detection of the Coronavirus, but it is expected that in the future, away from the epidemic, it can help track down other diseases.
