Calcium Blood Test

$38.00 AUD

Want to check your calcium levels and understand what they mean for your bone and parathyroid health?

Measures total calcium in the blood, a mineral involved in bone structure, nerve signalling and muscle function. Abnormal levels can indicate conditions affecting the parathyroid glands, vitamin D metabolism, kidneys or bone turnover.

Overview

The Calcium test measures the level of this vital mineral in your blood, acting like a window into your body's internal construction crew. Calcium serves as your body's master builder and communication system rolled into one – it builds and maintains strong bones and teeth, helps your muscles contract smoothly (including your heart), enables your nerves to send clear signals throughout your body, and even helps your blood clot properly when you get a cut. Think of calcium as the multitasking mineral that keeps your body's framework solid while ensuring all your internal systems can talk to each other effectively.

When your calcium levels are too high or too low, it's like having a construction site with either too many or too few building materials – things start to go wrong. Low calcium might show up as muscle cramps, tingling in your fingers, or weakening bones, while high levels could signal problems with your parathyroid glands or other underlying conditions. This simple blood test is especially valuable if you're experiencing unexplained muscle cramps, have concerns about bone health, or if your doctor wants to check how well your parathyroid glands are managing your body's calcium balance, giving you clear insights into whether your body's mineral management system is working as it should.

Symptoms

Suited to people investigating bone loss or osteoporosis risk, suspected parathyroid disorders, unexplained muscle cramps or weakness, kidney stones, or fatigue. Often included in broader metabolic panels.

Questions

  • It measures the total amount of calcium circulating in your blood, including calcium bound to proteins and free (ionised) calcium. This gives your practitioner information about bone health, parathyroid function, and how your muscles and nerves are working.
  • No fasting is required for a standard serum calcium test. You can eat and drink normally beforehand. Let your practitioner know about any supplements or medications you take, as these can influence results.
  • The most common causes of elevated serum calcium include overactive parathyroid glands (hyperparathyroidism) and certain cancers. Other causes include excess vitamin D intake, some medications, and prolonged immobility. Your practitioner will investigate the underlying cause.
  • Low serum calcium can result from underactive parathyroid glands (hypoparathyroidism), vitamin D deficiency, low magnesium, kidney conditions, or certain medications. Symptoms can include muscle cramps, tingling, and fatigue.
  • No. This test measures total serum calcium, which is the standard first-line measurement. Ionised (free) calcium testing is a separate, more specialised test that directly measures the active form of calcium. Your practitioner will advise if ionised calcium testing is needed.
  • Results are sent directly to you via the Bloody Good Tests platform. Share them with your GP or healthcare practitioner for interpretation in the context of your symptoms and health history.

How to prepare

No fasting required for a standard serum calcium test. Drink water as normal.

Let your practitioner know about any calcium supplements, vitamin D, antacids or medications you take regularly, as these can affect results. Your practitioner may advise whether to pause any supplements before testing. A healthcare professional will take a blood sample from a vein in your arm.

After the test

Share your results with your GP or a relevant specialist. If your calcium is outside the reference range, your practitioner may request additional tests such as parathyroid hormone (PTH), vitamin D (25-OH), phosphate, albumin, or kidney function markers.

If your result is normal but you have ongoing symptoms, your practitioner may investigate other causes.

Your test results will be available in your private dashboard. If there are any urgent issues, we'll let you know so you can follow up with your health professional.

Understanding results

Results are reported as total serum calcium in millimoles per litre (mmol/L). The reference range for adults is typically 2.10 to 2.60 mmol/L, though this can vary slightly between laboratories.

Levels above the reference range (hypercalcaemia) may be associated with overactive parathyroid glands, excess vitamin D, certain bone conditions, or other causes. Levels below the reference range (hypocalcaemia) may be associated with low parathyroid hormone, vitamin D deficiency, magnesium deficiency, or kidney conditions.

A single result outside range does not confirm a diagnosis. Your practitioner will review your result alongside symptoms, medications, and other test findings before drawing conclusions or recommending further investigation.

Simple health checks in my control

I didn't know that private blood tests were an option. Tried this platform as the packages suited what I wanted for a good price. Easy to follow instructions, and super quick results. Platform provides more information than my gp's ever have on the tests and what the results meant. Would like more clinics to be able to test at (specifically Capital Pathology) but there is a decent network. Will continue to use.
