Why this test
Calcium does far more than build bones — it regulates your heartbeat, nerve signals, and muscle contractions.
Blood calcium is tightly controlled by the parathyroid glands. Levels outside the reference range may reflect issues with parathyroid function, vitamin D status, kidney health, or dietary intake. This test is often ordered alongside PTH and vitamin D for a complete picture.
Understanding your results
Within reference range
Your calcium level is within the expected range
Low-normal
Within range but worth monitoring alongside vitamin D and PTH
Below reference range
May be worth discussing with your healthcare practitioner — can reflect dietary, hormonal, or kidney-related factors
Above reference range
Elevated calcium may warrant further investigation — discuss with your healthcare practitioner
Reference ranges vary by laboratory and personal context. Your result is shown against the lab's range in your dashboard, alongside what it means.

Elevated blood calcium (hypercalcaemia) is most commonly related to overactive parathyroid glands or, less commonly, certain medications or vitamin D excess. Your healthcare practitioner can advise on next steps.
Blood calcium reflects the calcium your body has circulating, which is tightly regulated — not simply how much calcium you eat. It is a different measurement to dietary intake.
If monitoring a parathyroid or kidney condition, annually or as directed by your healthcare practitioner. For general health awareness, every 2-3 years alongside a broader health check is typical.
