- Selected adults with borderline or intermediate cardiovascular risk
- People whose statin or prevention decision remains uncertain after standard risk assessment
- People with strong family history when a clinician believes the result will change action

TEST PASSPORT · REVIEWED JULY 2026
Coronary artery calcium CT
See calcified coronary plaque when the prevention decision is genuinely uncertain.A CAC score can reclassify risk in selected adults. It uses radiation, sees calcified rather than all plaque and is not a universal annual biohacking scan.

HOW TO USE THIS PAGE
Decide whether this test deserves a place in your plan.
- 01Confirm the question
Be clear about what decision the result would change before ordering.
- 02Check fit and preparation
Review who it helps, who should pause and how to protect the quality of the signal.
- 03Plan the response
Know what you will do with a normal, abnormal or unclear result.
01 / WHO SHOULD TAKE IT
Fit the test to
the person.
Testing is useful when the result can change a real decision. These are educational selection criteria, not a diagnosis or personal order.- Young low-risk adults seeking a longevity score
- People with known coronary disease where management is already clear
- Annual tracking without a decision
02 / SIGNAL VS. STORY
What it tells you.
What it cannot.
01
Agatston score of calcified coronary plaque
02
Age/sex percentile context where provided
03
Whether plaque burden may justify stronger prevention
01
A score of zero does not exclude noncalcified plaque or guarantee no event
02
Radiation is low but not zero
03
Incidental findings can trigger follow-up
03 / MARKERS + RANGES
Read the panel
without chasing flags.
The report should show its own method, units and laboratory reference interval. Clinical decision thresholds may be different from a lab interval. We do not invent a universal “optimal” range where authoritative guidance does not support one.Use the laboratory unit and method, then interpret with symptoms, trend and the decision this marker can change.

MEN, WOMEN + LIFE-STAGE CONTEXT
The correct range is personal context—not pink versus blue numbers.
Where biology differs, we call it out. Clinical interpretation should also reflect organs present, hormone therapy, pregnancy, age, medications and health history.
Calcification may appear later on average; pregnancy status and menopause-related risk context matter.
Plaque often appears earlier on average, but age and total risk still determine whether scanning is useful.
04 / PREPARATION
Protect the quality
of the signal.
The best assay cannot rescue the wrong timing, wrong specimen or wrong question. Follow the ordering clinician and laboratory instructions when they differ from this general guide.Calculate standard risk first and decide what result would change.
Usually no contrast; the facility provides specific caffeine, clothing and heart-rate instructions.
Tell the facility if pregnancy is possible because the test uses ionizing radiation.
REPEAT CADENCEUsually a one-time decision aid. Rescanning intervals, if any, should be individualized rather than annual.
05 / AFTER THE RESULT
Turn the number
into a next step.
- 01
Use the result to make a prevention decision
- 02
Treat risk—not the image itself
- 03
Route incidental findings through an appropriate clinician
DO NOT WAIT ON A CONSUMER TEST
New chest pressure or exertional symptoms need clinical evaluation; CAC is not an emergency test
