Intra-operative PTH Monitoring Now Available for Parathyroid Surgery in Auckland Patients undergoing parathyroid surgery in Auckland can now benefit from a significant advance in endocrine surgical care. Dr John Chaplin has introduced intra-operative parathyroid hormone (ioPTH) monitoring for parathyroidectomy patients at Gillies Hospital, marking the first time this technology has been available locally.

By looking for specific gene mutations, gene fusions, and other genetic alterations, molecular testing helps determine whether a thyroid nodule is likely to be benign (non-cancerous) or malignant (cancerous). It is particularly helpful when traditional cytology (micr
