Research at Vedant Diagnostic Center

Vedant Diagnostic Center is more than an NABL-accredited (ISO 15189) clinical laboratory — it is an active centre of laboratory-medicine research. Our team studies how Six Sigma metrics, risk assessment (FMEA), and corrective-and-preventive-action (CAPA) frameworks can reduce errors across the total testing cycle, so that every report we issue is backed by internationally benchmarked quality systems. Our work has been published in leading peer-reviewed international journals, and our founder's quality-improvement methods have been featured on Westgard QC, the world's foremost laboratory quality-control resource.
