Quest Diagnostics Inc.
Quest Diagnostics (DGX) is a leading US clinical laboratory services company that provides diagnostic testing, information and services to healthcare providers, hospitals, employers and insurers. Its business is driven by volume of tests, reimbursement rates and specialised, higher-margin diagnostics such as molecular and genomics testing. The company benefits from scale, extensive logistics and long-term contracts but faces competition from other national labs, hospital systems and growing point-of-care testing. Key investor considerations include demand trends for routine and specialised tests, reimbursement and regulatory pressure, and capital investment in automation and new technologies. Quest has historically returned cash via dividends and buybacks, though investors should weigh yield against growth prospects and margin sensitivity. Market cap is about $20.54bn.
