Quick answer: There is no single test, five-test bundle or decade-based imaging schedule proven to measure or extend one person's “healthspan.” A conservative plan starts with history, family history, symptoms, blood pressure, smoking, current cancer screening and selected laboratory tests. ApoB, HbA1c, CAC, DEXA, CCTA, brain MRA and full-body MRI answer narrower questions and should not be ordered automatically by age.
“Longevity” is not a standardized medical specialty package. This article separates established preventive care from optional risk-refinement tests and examinations that lack evidence for routine use in asymptomatic, average-risk adults. It cannot prescribe a schedule or treatment target for an individual reader.
Start with established prevention
- Review symptoms, personal and family history, medicines, smoking, alcohol, sleep and activity.
- Measure blood pressure and consider standard lipid, glucose, kidney and other tests when indicated.
- Follow current breast, cervical, colorectal, oral and lung cancer screening eligibility.
- Address modifiable risks and repeat tests only when the result is likely to change care.
Five commonly discussed tests—and their limits
ApoB
ApoB measures the number of atherogenic lipoprotein particles and may add information to cardiovascular-risk assessment. This page does not assign a universal starting age, target or repeat interval. Interpretation depends on overall risk, existing disease, medicines and the responsible clinician's guideline-based judgement.
Recorded market range: USD $30–$50 in Taiwan and $80–$200 in the US. These are dated comparison ranges, not a live quote; laboratory method, consultation and package inclusion may differ.
Hemoglobin A1c
HbA1c is one validated test for prediabetes and diabetes. Conditions that alter red-cell turnover can affect the result, and an abnormal result may need confirmation. USPSTF recommends screening nonpregnant adults aged 35–70 who have overweight or obesity and considering earlier testing for additional risks. Evidence on the best interval after a normal result is limited.
Recorded market range: USD $15–$25 in Taiwan. Confirm the live price, test method and whether consultation is included.
Coronary artery calcium score
CAC is a non-contrast CT measure of calcified coronary plaque. It may refine risk for selected adults when a prevention decision remains uncertain after standard assessment. A score of zero does not exclude non-calcified plaque or guarantee that a future event will not occur. This article does not recommend starting at 40 or repeating at a fixed interval.
Recorded market ranges: USD $250–$400 in Taiwan and $300–$800 in the US. Match protocol, interpretation and facility fees before comparing.
DEXA
Bone-density DEXA and body-composition DEXA are related but different uses. Current USPSTF guidance recommends osteoporosis screening for women aged 65 or older and younger postmenopausal women at increased fracture risk; evidence is insufficient for population screening in men. Body-composition tracking does not by itself create a medical need for repeated scans.
Recorded market ranges: USD $150–$250 in Taiwan and $200–$450 in the US. Confirm whether the price is for bone density, body composition or both.
Coronary CT angiography
CCTA uses ionizing radiation and iodinated contrast to image coronary anatomy. It may be appropriate for a defined clinical question, but age 50 or a calcium score threshold does not automatically make it the next test. Kidney function, prior reactions, symptoms, risk and alternatives must be considered.
Recorded comparison: USD $799 in Taiwan and a US range of $1,500–$3,500. Confirm the current price, contrast, heart-rate preparation, interpretation and facility charges.
Tests that are not routine longevity baselines
ACR states that evidence is insufficient to recommend total-body MRI screening for asymptomatic adults without risk factors, symptoms or family history. Brain MRA, cognitive imaging and CCTA also require a specific question; more imaging is not automatically better. Incidental findings may lead to more tests, procedures, anxiety and cost.
A large laboratory panel can likewise create borderline and false-positive results. Tumour markers generally do not have adequate sensitivity and specificity to function as a broad cancer screen in asymptomatic people.
No decade-based package prescription
This article does not recommend an Essentials package in the 20s, Advanced in the 30s, Premium in the 40s or Plus in the 50s. Package selection is a transaction choice after medical suitability is assessed. The live catalogue must supply current prices, inclusions, facility availability and exclusions.
How to use prices safely
- Record currency, geography, service scope, exclusions and as-of date.
- Do not compare a single-region MRI with a full-body product.
- Confirm contrast, sedation, pathology, report language, DICOM and follow-up.
- Use the live catalogue and written quotation if they differ from the article.
