US scientists have Developed a low cost swab test that can diagnose Coronavirus infection in only 45minutes , An advance that may help health officials scrambling to cope with testing backlogs as the number of COVID19 cases continues to rise .
The test named as SARS CoV-2 DETECTOR is easy to interpret and implement and requires no specialised equipment as mentioned by researchers from the University of California, San Francisco in the US .
This quality is likely to make the test reported in a paper published in the Journal Nature Biotechnology more widely available current crop of Coronavirus test kits, they said .
Though the new COVID19 test has yet to receive formal approval for clinical use from the United States Food and Drug Administration , the Researchers are clinically validating the COVID19 test in an attempt to fast track the approval process .
So the availability and introduction of CRISPR technology will accelerate the deployment of the next generation of Coronavirus test to diagnose COVID19 infection , said Charles Chiu a professor at UCSF and co-lead developer of the new COVID19 test .
The new SARS CoV-2 DETECTOR assay is one of the first to use CRISPR gene targeting technology to test for the presence of novel COVID19 , the Researchers said .
Since CRISPR technology can be modified to target any kind of genetic sequence , the Researchers programmed the test to home in on two targets region in the genome of the novel COVID19 .
One of those sequence is same to all SARS like Coronavirus, while another is unique to SARS CoV-2 that causes COVID19 according to the Researchers
Testing for the presence of both the sequences ensures that the new COVID19 detector tool can distinguish between closely related virus and SARS CoV-2, researchers said .
As similar to the diagnostic kits currently in use , the new test can detect the novel COVID19 in samples obtained from the respiratory swab , they said .
While the widely used test based on PCR techniques take nearly 4hours to produce the result from the respiratory sample , the new COVID19 detector can detect it in only 45minutes , researchers said .
Researchers noted that another plus point of the new Covid19 DETECTOR test is that it can be performed in any lab , using common equipments and off the shelf reagents .
It stands in contrast to Polymerase Chain Test reaction test which require specialised expensive equipment limiting those COVID19 test to to well equipped diagnostics lab, researchers said …
