Clinical Virology Laboratory at the Institute provides a full range of diagnostic services for the detection and monitoring of viral illnesses in both the adult and pediatric patient. Most of the functioning of the department has been automated to an extent, in keeping with international standards. The laboratory performs diagnostic services for the detection and monitoring of viral diseases for the full range of Hepatitis viruses (Hepatitis A, B, C, D and E). The laboratory is fully equipped to diagnose and monitor all most all the viruses causing infections in transplant recipients and other immune compromised patients. A BSL level grade 2/3 molecular diagnostic facility is available in the molecular set up. Viral genotyping is routinely being done. Multiplex Real time PCRs is the strength of the laboratory including Respiratory viral PCR for 33 different pathogens together. The laboratory takes pride in performing several diagnostic assays for the first time in the country, like testing for drug resistant substitutions in HCV (RAS) , antiviral drug resistance testing in HBV; HBs Ag quantification in clinical samples ; testing for Occult HBV infection and ccc DNA in biopsy samples; screening for various mutations in HBV like Pre-core, Basal core promoter mutations; HEV RNA Quantification and genotyping; EBV and CMV Quantification in tissue biopsy samples. Furthermore, the laboratory is actively involved in the investigation of any outbreak that grips the city like recent Influenza, Dengue and Chikungunya outbreaks in the capital. Recently, point of care of Molecular diagnostics was started in the laboratory in assays like HCV RNA, H1NI and HIV viral load testing. Microarray platform for syndromic viral infection testing is also available in the laboratory. Virology laboratory takes pride in being made as one of the testing laboratories by Central Drugs Standard Control Organization for the validation of Hepatitis diagnostic kits. Virology laboratory at ILBS is also nominated by ICMR as one of the Apex Viral Hepatitis laboratories in the country to look after external quality assurance (EQAS) in various Virology labs across the Nation. The lab has been active in initiating teaching modules and programs in clinical virology. NABL accreditation was awarded to the lab in 2013 and is the one of the very few NABL accredited molecular virology lab in India. The Molecular Lab participates in EQAS by Royal College of Pathology, Australia. The Virology Lab has made an exhaustive protocol for Needle Stick Injuries, post exposure prophylaxis for healthcare professionals at ILBS and also keep a track of the HBV immunization status of the entire ILBS staff. The laboratory also supervises the unique Needle stick injury control programme through our website: The ILBS NSI – website aims to provide platform for a centralized registry for needle stick injuries. The vision of ILBS is not only to create an institutional database on needle stick/ sharps injuries but to expand it as a statewide and thereafter national NSI Registry. A unique PDCC course in Hepatovirology has been introduced from August 2014 to train young budding microbiologists in this field. As a part of World Health Organization collaborative Center (WHO-CC) in Viral Hepatitis, Virology laboratory is actively involved in imparting capacity building training to Microbiologists and other laboratory staff across the Nation.
