Oxford University Develops New Rapid Antigen Test.

Scientists at Oxford University have developed a new testing method called to be as New Rapid Antigen Test to detect the COVID-19 virus

Highlights

  • The new test makes use of artificial intelligence in order to locate single intact virus particles.
  • The entire process will take less than five minutes to show the end results.
  • The test does not require any complex steps such as amplification that are  used in RT-PCR testing.
  • The testing method would also be effective for screening the other viral diseases.

RT PCR

RT PCR is the Reverse transcription polymerases chain reaction. The PCR technique was invented by the American biochemist named Kary. He was presented the Nobel Prize for Chemistry in 1993. Under this technique, copies of a deoxyribonucleic acid (DNA) are created using a Polymerase enzyme. The ‘chain reaction’ is carried out to signify how the DNA fragments have been copied. A fluorescent DNA binding dye “probe” is added to the DNA that shows the presence of the virus on a fluorometer. The coronavirus is made of ribonucleic acid (RNA). So, to detect coronavirus, RNA is first converted into DNA by a technique called reverse transcription. After that, Copies of the DNA are made and amplified.

Rapid Antigen Detection Test

The test is based on the swapped nasal samples. The testing is done to detect the antigen (Foreign substances that induce immune response of the body)  that are found in the COVID-19 virus.
