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.
