The Institute of Clinical Microbiology and Immunology is committed to establishing itself as a centre of excellence by providing high-quality diagnostic, educational, training and research services. The department is seen as a trendsetter in India by embracing the latest cutting-edge technologies in the quest for early, accurate and affordable diagnoses for better clinical management of patients. This totally pro-active department traces all positive reports back to the bedside by sharing the fi ndings with the treating unit for better understanding and actionable results. This has helped us to detect rare diseases such as cryptococcal meningitis, tubercular brain abscess, disseminated nocardiosis, melioidosis, cardiac hydatidosis and systemic histoplasmosis, to name a few.

  • Timings: The department is situated on the 1st Floor of the Old Building and provides 24 × 7 diagnostic services.

II. Quality control

  • External quality assurance scheme (EQAS) centre Our department has been running the IAMM-EQAS since 2014 under the aegis of the Indian Association of Medical Microbiologists. Our centre caters to the North and North-East Zone of India. Currently, we have approximately 650 laboratories enrolled with our centre.
  • NABL accreditation The effi ciency of the laboratory in meticulously following internationally recommended techniques, adhering to various elaborate in-built control protocols and guidelines refl ects in the accurate test results. Our laboratory has been NABL (ISO 15189:2003) accredited since 2004. It is accredited as a PT provider with NABL (ISO17043).
  • Participation in EQAS programmes To maintain the highest standard and monitor the quality of our reports we are enrolled with various external organizations for EQAS, e.g
    • Bacteriology and serology: Christian Medical College, Vellore
    • Molecular tests: Christian Medical College, Vellore
    • Mycology: PGIMER, Chandigarh
