In a bid to ramp up the testing capacity, the Indian Council of Medical Research (ICMR) has issued revised guidelines for TrueNat testing and said that it is now a comprehensive assay for screening and confirmation of COVID-19 cases. Earlier on April 10, the ICMR had approved the use of TrueNat system for conducting coronavirus tests but recommended it only as a screening test.
In its revised guidelines, the apex health body has said: "TrueNat system is now a comprehensive assay for screening and confirmation of COVID-19 cases". According to the guidelines, all samples of suspect COVID-19 should be first tested by the E gene screening assay. All negatives are to be considered as true negatives. All positive samples should be subjected to confirmation by another step.
The step 2 is RdRp gene confirmatory assay. All samples that test positive by this assay must be considered as true positive. "No further RT-PCR based confirmation is required for samples that are positive after step 2 of the assay," the revised guidelines stated. All positive and negative results must be reported to the ICMR portal in real-time manner.
In a massive development on Monday, the Indian Council of Medical Research (ICMR), on Monday, has revised its testing strategy for Coronavirus (COVID-19) cases. As per the new guidelines, asymptomatic direct and high-risk contacts of COVID-19 positive patients must be tested between 5-10 days of coming into contact.
The death toll due to COVID-19 on Wednesday rose to 3,303 and the number of cases climbed to 1,06,750 in the country, registering an increase of 140 deaths and a record spike of 5,611 cases in the last 24 hours, according to the Union Health Ministry.
