RT-PCR 2100
It is the gold standard test for Covid-19 which gives a most accurate result. RT-PCR test is done using swabs taken from nose or throat. RNA is the genetic material present in coronavirus, but swabs taken consists of only small amount of RNA which is not enough for testing process. So RNA is converted to DNA and then copies are created using PCR process. In the next process, small pieces of DNA to bind DNA of corona is collected. Along with this, fluorescent dye is also required. All the three, swab sample, DNA pieces binded with DNA of corona, fluorescent dye is placed in PCR machine. After binding process if fluorescent signal is shown there is the presence of coronavirus.
