The department of cardiac biochemistry under the Cardiothoracic center (CTC) caters to the inpatients and outpatients of Cardiology and CTVS. In addition to patient care services the department is active in research in the area of developmental origin of adult chronic diseases, telomere biology, endothelial progenitor cells and trans fatty acids.
The department under one roof does testing in the areas of clinical chemistry, hematology, coagulation, hormones, cardiac drugs, lipids, catecholamine, marker of heart transplant evaluation, markers of inflammation and in addition assessment of novel risk factors for CAD like homocysteine, lipoprotein(a), apolipoproteins A1 and B. The department has excellent infrastructure and most of the investigations are carried out on automated instruments. Facilities for doing genetic analysis are also available. On an average 250 patients samples are analyzed in the lab every day.
The cardiac biochemistry lab is externally validated through quality assessment scheme (UKNEQAS) accredited to BIRMINGHAM, UK and RIQAS (Randox external quality assessment scheme) and has shown a consistently good performance.
