ICMR validates, recommends indigenous COVID-19 tests to reduce dependency on other countries – Firstpost

Indian researchers and authorities have prioritized to cut back dependence on different nations by growing and validating indigenous diagnostic assays for COVID-19 testing. A complete of 11 RT-PCR-based indigenous assays have been validated and really helpful for the testing of COVID-19. This has been revealed by the Indian Council of Medical Analysis (ICMR).

As COVID-19 circumstances are growing; the restricted provide of diagnostic kits required for its prognosis stays a priority. To fulfill the demand for diagnostic gadgets, indigenous manufacturing and speedy validation have grow to be mandatory. Indigenous manufacturing of diagnostic materials to make sure its uninterrupted availability might be a game-changer particularly in India, a rustic with a inhabitants load of greater than 130 crores.

ICMR had earlier validated the indigenous TrueNat assay for Tuberculosis (TB). The take a look at is WHO pre-qualified and is included as a dependable and correct technique for fast screening of TB sufferers. The TrueNat assay has additionally been validated by ICMR-Nationwide Institute of Virology (NIV) as some extent of care take a look at for Nipah virus illness.

In April 2020, an indigenous producer developed TrueNat assay for screening of SARS-CoV-2 that causes COVID-19. ICMR undertook profitable validation of the E-gene screening assay, following which TrueNat-based testing has been initiated by the states for SARS-CoV-2 detection. From April 2020 until date, greater than 1.three lakh screening exams have been performed by states. Nonetheless, the rate-limiting step has been the dearth of TrueNat confirmatory assay. All of the TrueNat constructive samples needed to be confirmed by RT-PCR-based exams both positioned in the identical or totally different laboratory.

Not too long ago, the indigenous producer has additionally developed an RdRp gene-based confirmatory assay of TrueNat, which has been efficiently validated once more by ICMR and has been discovered to have excessive sensitivity and specificity. Each the validations have been stringently performed by Division of Well being Analysis (DHR)/ICMR Virus Analysis and Diagnostic Laboratory (VRDL) at Bangalore Medical Faculty and Analysis Institute, Bengaluru.

ICMR has now really helpful the TrueNat COVID-19 take a look at as a two-step take a look at: the 1st step, i.e., E-gene screening assay for all COVID-19 suspect samples to be adopted by step two for the RdRp-based confirmatory take a look at in all E-gene positives.

This totally indigenous diagnostic platform provides a dependable and reasonably priced choice to reinforce the SARS-CoV-2 testing capability in India. The platform includes a TrueNat machine, inbuilt RNA extraction system, RT-PCR chips, assortment swabs and viral lysis medium (VLM). The only assay has a turnaround time of 35-50 minutes for 1-Four samples with a complete of 12-48 samples being examined per day, relying upon the kind of machine. The biosafety and biosecurity necessities are minimal in view of the pattern being collected in VLM, which inactivates the virus. The take a look at can be utilized on the stage of district hospital/main well being centres additionally.
