Dr Yegna Narayana Iyer was the first head of Biochemistry. The clinical laboratory of the Department of Biochemistry works 24×7 to provide timely and reliable reports on a wide range of biochemical parameters. The results are reviewed by highly experienced and qualified staff before they are released. Regular performance checks are conducted by running control samples to keep track of the accuracy, precision and reproducibility of the analytical procedures at the department, headed by Dr G. Jeyachandran.

Biorad, an internationally recognised quality assurance programme, has ranked this department as amongst the best in the country. The clinical biochemistry laboratory has recently been granted accreditation by the National Accreditation Board for Testing and calibration Laboratories (NABL), an autonomous body that recognises technical competence of labs. It is the only laboratory among all the medical colleges affiliated to the Tamil Nadu Dr MGR Medical University that has been accredited by NABL and is considered as a ‘model lab’ for audit by international bodies such as APLAC and ILAC.


The undergraduate training of the department includes theory classes which are interactive and student friendly, clinically relevant practical sessions and OSPE/clinical case studies to trigger interest in the concepts of biochemistry. The faculty do provide additional academic support for slow learners and feedback is regularly given to students on their performance in examinations.

The overall competence and academic excellence of post graduates is enhanced by training them in undergraduate teaching, clinical biochemistry laboratory procedures & interpretations, total quality assurance and research projects. They are encouraged to participate and present research papers in conferences.


The department is equipped with instruments to support undergraduate and postgraduate training & research.

The Clinical Biochemistry Laboratory of PSG Hospitals Diagnostic Centre offers routine and special tests to the patients. The Laboratory tests are accredited by the National Accreditation Board for Testing and Calibration Laboratories (NABL), Department of Science and Technology, New Delhi. The Clinical Biochemistry Laboratory, with state-of-the-art equipment works round the clock. The laboratory is equipped with fully automated analysers for routine chemistry, hormone assays, tumour markers and special proteins, critical care analytes, glycosylated haemoglobin. There is also a fully automated electrophoretic system. Sample barcoding and inter-phasing of the analysers make the system error free. Transport of samples collected at different wards and outpatient sample collection department by a pneumatic system and release of reports in the Hospital Information System within a short time enable early diagnosis and treatment.
