A rapid parathyroid hormone (PTH) assay is an intraoperative blood test used during parathyroid or thyroid surgery to confirm complete removal of overactive gland tissue. At ENT Central in Palmerston North, Dr Naveed Basheeth uses this cutting-edge technique to ensure surgical accuracy and minimize complications—delivering safe, precise, and personalized care.
How quickly are the results available during surgery?
The rapid PTH assay provides results within approximately 10 minutes of removing the suspected parathyroid gland. This immediate feedback allows Dr. Basheeth to determine—while the patient is still in surgery—whether the overactive gland has been successfully excised, ensuring greater precision and avoiding unnecessary additional exploration.
How does this test help reduce the need for another surgery?
By confirming a significant drop in parathyroid hormone levels during the procedure, the assay ensures the abnormal gland has been removed entirely. This real-time confirmation dramatically lowers the risk of persistent hyperparathyroidism and the need for repeat surgery, giving patients peace of mind and better long-term outcomes.
Is the rapid PTH assay safe?
Yes, it is completely safe. The assay involves drawing a small blood sample during surgery and poses no added risk to the patient. It does not prolong the operation or cause discomfort, and its benefits far outweigh any minimal inconvenience, making it a valuable tool in modern parathyroid surgery.
