In yet another action front in search of solutions that contribute to the mitigation of the pandemic caused by the new coronavirus, the Laboratory of Respiratory Viruses and Measles of the Oswaldo Cruz Institute (IOC/Fiocruz) and the Institute of Technology in Immunobiologicals (Bio-Manguinhos/Fiocruz) developed two new molecular tests for the diagnosis of Covid-19.
The first, whose application for registration was submitted to the National Health Surveillance Agency (Anvisa) last Tuesday (18/01), is the Molecular Kit Inf A/Inf B/SC2, an RT-type test. PCR that differentiates Influenza A, B and SARS-CoV-2 viruses, enabling the diagnosis of these diseases in a single test.
The Quadriplex SC2/VOC molecular kit, which also uses RT-PCR technology, will allow the detection and screening of Alpha, Beta, Gamma, Delta and Omicron variants of the SARS-CoV-2 virus. Its use is indicated for diagnosis and viral screening based on the identification of potentially important strains for public health and epidemiological surveillance in the country, designated by the World Health Organization (WHO) as VOCs (acronym for variants of concern). The result of this test indicates the presence or absence of these variants. In order to identify the variant, genetic sequencing of the sample would still be necessary. The Quadriplex test must be submitted for registration with Anvisa by next week.
“Whenever we talk about respiratory infection, we are referring to a type of disease that can be caused by a huge range of microorganisms. Because they have very similar symptoms, identifying the causative agent of the disease without carrying out a laboratory diagnosis is challenging. The availability of these kits in the Unified Health System [SUS] will allow, in an economical way and with high processing, the timely viral identification of these agents, with the method that is the gold standard for the diagnosis of diseases caused by respiratory viruses in the world”, explains the virologist and researcher at the Laboratory of Respiratory Viruses and Measles of IOC/Fioccrosses Fernando Motta. The laboratory acts as a reference in respiratory viruses for the Ministry of Health.
