• Analyst Opinion
  • Shambhu Nath Jha, Principal Consultant at Fact.MR, says "Critical-care testing is migrating to the bedside, and that migration favors suppliers with connected platforms rather than the broadest catalog alone. New rapid molecular point-of-care assays, some returning results in about 15 minutes, change clinical management in intensive care and emergency settings. Multiyear reagent agreements lock in revenue and slow switching, so installed base matters more than list price. China and India are expanding fastest as hospital and ICU capacity grows. The advantage goes to firms that combine rapid results with decision-support integration and dependable service, since hospitals are standardizing on data-connected systems, not standalone analyzers."
