About the Laboratory

YRGCARE Infectious Diseases (ID) Laboratory located at the Voluntary Health Services (VHS) Hospital Campus, Taramani, Chennai-600113, was established in 2000 in collaboration with Johns Hopkins University, Baltimore, USA and Brown University, Rhode Island, USA with a financial grant from the National Institutes of Health (NIH), an agency of the United States Department of Health.

This ID laboratory is staffed by experienced and qualified professionals and has good infrastructure to meet all the emerging needs of diagnosing HIV and other infectious diseases (such as sexually transmitted infections [STI], tuberculosis [TB] and viral hepatitis) with state-of-the-art equipment in its 8500 square foot facility. The laboratory’s divisions are: Serology; Microbiology & Mycobacteriology; Biochemistry; Hematology & Immunohematology; Immunology & Core Immunology; and Molecular Biology & Genotyping.

The laboratory is engaged primarily in quality assured diagnostic services with the ISO 15189:2012 quality management system, conducting biomedical research in the areas of the basic sciences and offering educational programs organized by qualified scientists/faculty. Laboratory staff have attended several workshops on diagnostic and research methodology; this includes international training programmes.

The major diagnostic laboratory services include:

  • HIV/ART monitoring tests (CD4 count and HIV-1 viral load).
  • Opportunistic Infections (OIs) including bacterial, fungal, parasitic and TB infections.
  • Sexually Transmitted Infections (STIs).
  • Viral hepatitis.
  • Drug toxicity related tests.
  • PCR (Real Time PCR, Multiplex PCR) based molecular tests for HIV-1, HBV, HCV, TB and CT/NG.
  • Genotyping by Sanger’s capillary gene sequencing for HIV-1, HBV and HCV.
