Covid 19 testing method and Capacity
Covid Testing method and Capacity
It’s going to be four months when WHO confirmed human to human transmission by Covid19 and now we have more than 8 million cases worldwide with this virus and it is still growing. Any vaccine possibility is not before end of this year. So at present what authorities should do is just increasing the Covid testing method and Capacity. In India too testing capacity has been increased to 3lakh daily considering the population mass and density. But good thing is that like mortality the infected cases is also very low like if we compare it with US their positive case is around 10% or more while in India it is just over 3%.
Worldwide there are mainly two testing methods, Polymerase Chain Reaction or PCR and Rapid antibody or Serological test. Both test follows different approach, while in first PCR test nasal and throat swab is taken the second Rapid test blood as sample. The PCR test has been recommended by ICMR as gold standard frontline test which is more accurate and reliable but it is advisable for testing in large number because it is labor intensive, time taking and expensive as it involves RNA extracting by machine and expert technician. Since the process is lengthy each stage should be done carefully otherwise it may give faulty result. One PCR test is charged Rs4500 and result will be available after 4hours.Rapid antibody test however is less expensive can be administered on site and fast but it is more effective in containment areas because if someone gets infected with the virus, body develops antibody to fight with it. This test explores immunoglobulin M and G.The ICMR has laid out strategy to use antibody kits.
To increase testing capacity government has authorized private players also to conduct these tests and after court’s order to reduce testing charge government is exploring possibility for price reduction and curb profiteering by private parties. For more related covid 19 vaccine click on it.
