DIAGNOSTIC OVERVIEW

What CT Calcium Score Is

Calcified plaque builds in artery walls over time and can be measured directly with a CT scan. The result is expressed as a score, which is used alongside your other markers to inform a fuller picture of heart health. It is a quick scan that produces a single, well-understood figure.

Why it's worth it

Sees risk that bloods can miss.

One clear, well-validated number.

Low-dose, quick, and clinician-reviewed.

DIAGNOSTIC DETAILS

What it measures

The scan produces a coronary calcium score, reflecting the amount of calcified plaque detected in your coronary arteries.

Get started with Precursor

Calcified Plaque

The scan detects calcium deposits in your coronary arteries, a direct sign of atherosclerosis already present. Because calcium reflects long-term build-up, it reveals risk that cholesterol numbers and how you feel can easily miss.

Your Calcium Score

The result is a single, well-validated Agatston score. It turns an invisible process into one clear number your clinician can act on, and a starting point far more personal than a population risk chart alone.

Used With Your Markers

Combined with your bloods and history to sharpen your overall heart-risk picture.

"A calcium score often tells us more about someone's real heart risk than their cholesterol alone. Catching build-up early, while there is time to act, is clearly the head start this scan can give."

FAQs

Your Questions, Answered

How do I book a test?

Choose your test and a time that suits you online, then visit one of our partner locations. If any preparation is needed, such as fasting, we tell you clearly when you book.

When and how do I get my results?

Your results appear in the Precursor app once your sample or scan has been processed, laid out in plain language rather than a wall of numbers. Turnaround depends on the test, and we give you a timeframe when you book.

Will someone explain my results to me?

Yes. A clinician reviews your results, flags anything worth your attention and helps you understand what they mean and what, if anything, to do next. You are never left to interpret them alone.

Where can I get tested?

We operate nationally through a network of partner locations across most major cities and regional centres. When you book, you simply choose the location that is most convenient for you.

Do I need to prepare or fast beforehand?

It depends on the test. Some require fasting or other simple preparation, and others need nothing at all. Whatever applies, we tell you clearly at the time you book so there are no surprises on the day.

Can I track my results over time?

Yes. The Precursor app is built to show change between tests, so each result becomes a trend you can follow rather than a one-off snapshot. Retesting lets you see the effect of any changes you make.

How is my data handled and kept private?

Your health data is handled with care and kept private. Results are stored securely in the Precursor app and shared only with you and the clinicians involved in your care.

What happens if something needs further attention?

If your results surface something worth acting on, your clinician explains it calmly and talks you through sensible next steps. The aim is early clarity and considered action, never unnecessary alarm.
