  • • Parathyroid hormone has a short half life in vivo.
  • • Intraoperative parathyroid hormone measurement can guide the surgeon by confirming successful removal of parathyroid adenomas.
  • • Point of care testing with a dedicated analyser and technician in theatre is expensive.
  • • This study shows that intraoperative parathyroid hormone is feasible using a central laboratory based analyser available in most hospitals.
  • • There are potential cost savings when compared with point of care testing.
