TrueNat: Diagnostic machine for COVID-19Date: 11 April 2020 Tags: Miscellaneous
The Indian Council of Medical Research (ICMR) has approved the use of diagnostic machines used for testing drug-resistant tuberculosis for conducting coronavirus tests.
The ICMR has validated TruenatTM beta CoV test on TruelabTM workstation and has recommended it as a screening test. The TrueNat machines are used to test drug-resistant Tuberculosis (TB).
ICMR said throat/nasal swabs will be collected in the viral transport medium (VTM) with virus lysis buffer provided along with the kit.
Earlier studies have shown that virus lysis buffer neutralizes Nipah and H1N1 viruses. The results of stability of viral RNA after neutralization of SARS-CoV-2 by virus lysis buffer are awaited .
Till such time, Truenat beta CoV test should only be performed with all biosafety precautions in BSL-2 or BSL-3 setups at laboratories.
Its battery-operated kits are the size of a telephone and can be taken out into the field to test as many as 15 individuals a day. They range between Rs. 6.5 lakh and Rs. 12 lakh and have received both government and ICMR approval.
The testing kits uses Polymerase Chain Reaction (PCR) technology, which uses a swab from the throat to diagnose diseases, more accurate method when it comes to diagnosis.
