Genetic Services Unit of National Institute of Biomedical Genomics at P.G. Polyclinic of the S.S.K.M. Hospital, Kolkata

A Genomic Service Unit that is unique in this State, has been formed at PG Polyclinic in collaboration with National Institute of Biomedical Genomics, Kalyani; Biomedical Genomics Centre, Kolkata and this Department. This is a five year project.

Genetic Services Unit is now capable of carrying out 47 different types of molecular genetic tests after due standardization and cross-checking with national and international genetic testing laboratories, which cost Rs. 2.6 lakhs in private diagnostic centres.

From its inception in 2017, Genetic Services Unit has performed and reported molecular genetic tests for 1024 patients and families with rare diseases who were referred from 8 State Government Medical Institutions across Kolkata and Midnapore Medical College. The Unit offers free testing of patient samples and the market value of total testing done until November, 2018is around Rs. 98.8 lakhs. All genetic tests on patients are referred to GSU by clinicians. Results of tests are provided by GSU only to the referring clinicians, not directly to the patients.

Genetic Services Unit is now a collaborating member of the European Molecular Genetics Quality Network(EMQN) (Lab ID 2279), and has been successfully registered with the National Centre for Biotechnology Information (NCBI), United States of America; Gene Test Registry (GTR) (GTR Lab ID: 506786) ( Genetic Services Unit has registered a perfect score, that is, no mistakes, in a proficiency test conducted by the European Molecular Genetics Quality Network.

Following genetic tests have been standardized and service provision made ready by Genetic Services Unit:
