Parathyroid Hormone, PTH is needed for calcium and phosphate balance. PTH is involved in a feedback loop that includes vitamin D, calcium, magnesium, and phosphate.
It is produced by the parathyroid glands in the neck beside the thyroid gland, to help regulate blood calcium levels.

Medicines that may increase PTH levels include phosphates, anticonvulsants, steroids, isoniazid, lithium, and rifampin. Cimetidine and propranolol may decrease PTH levels.
This test requires a blood draw, which can be done at your local clinic. It will be analysed by an accredited lab, such as Karolinska, Aleris, or Unilabs. The first results are usually available within 48h.
What happens next?
The lab sends the results to your personal dashboard, with comments from both a doctor and a nutritionist. If results are abnormal, we recommend seeing a doctor and, if appropriate, booking an appointment with a Nordic Wellth nutrition lifestyle specialist.
