Recently the government had allowed two private companies - Indian company MyLab and German firm Altona Diagnostics - to supply COVID-19 test kits to both government as well as private testing laboratories in India.
Two South Korean firms, Seegene and SD Biosensor have received government approval to supply RT-PCR based Novel Coronavirus (COVID-19) diagnostic kits in India.
Mechanism
RT-PCR is known as Reverse transcription polymerase chain reaction.
It is a laboratory technique combining reverse transcription of RNA into DNA by using a polymerase chain reaction (PCR).
It is primarily used to measure the amount of specific RNA in a cell.
Its ability to quantify viral RNA makes the technique one of the most common ways of identifying viral strains.
Other firms
The government also approved 12 rapid antibody test kits for COVID-19 diagnosis.
The advantage of antibody rapid tests is that the result can be made available within 30 minutes.
The test comes positive after 7 to 10 days of infection.
While positive test indicates exposure to COVID-19, negative does not rule out the infection.
Biotech
The Bhopal of Madhya Pradesh based Biotech is second Indian firm to produce COVID-19 testing kit.
It is to produce real-time polymerase chain reaction (RT-PCR) COVID-19 testing kits.
The firm in the past had launched India’s first homemade test for another pandemic — H1N1 — commonly known as swine flu.
Mylab Discovery Solutions became the first Indian company to get commercial approval for its diagnostic test for covid-19 from the Central Drugs Standard Control Organization (CDSCO) after an evaluation by the Indian Council of Medical Research.
The test kit, named the Mylab Patho Detect COVID-19 Qualitative PCR kit, was developed in a record six weeks.
This project was headed by the head of research and development of Mylab “Minal Dakhave Bhosale”.
