Parathyroid hormone (PTH)
PTH is a major contributor to regulation of circulating calcium. Primary hyperparathyroidism occurs due to adenoma/carcinoma or hyperplastic syndromes and leads to hypercalcaemia. Secondary hyperparathyroidism can occur in renal failure.
Suspected hyperparathyroidism or hypoparathyroidism
2.2 – 14.0 pmol/L
|Sample & container required||EDTA (lavender top)|
|Sample volume||0.5 mL|
|Turnaround time||1 day|
The Biochemistry laboratory at Hammersmith hospital also provides an intraoperative PTH (ioPTH) service. The ioPTH assay can offer real-time quantitative assurance that all hypersecreting parathyroid tissue has been excised. The service is led by Prof Fausto Palazzo, Consultant Endocrine Surgeon.
