The routine checks that major guidelines recommend for healthy adults, by age and sex. Each one shows the guideline and grade it rests on. Your history, your results and your clinician decide what applies to you.
| Check | Who it is for | How often | Grade | Source |
|---|---|---|---|---|
| Blood pressure | Adults 18 and over | At routine visits | A | USPSTF: Hypertension in adults, screening (2021) |
| Tobacco use | Adults 18 and over | At routine visits | A | USPSTF: Tobacco use in adults, counselling and interventions (2021) |
| Weight (BMI 30 or higher) | Adults with a BMI of 30 or higher | Offer or refer to intensive, multicomponent behavioural weight-loss support | B | USPSTF: Obesity in adults, behavioural weight-loss interventions (2018) |
| Depression | Adults, including those 65 and over | At routine visits | B | USPSTF: Depression and suicide risk in adults, screening (2023) |
| Anxiety | Adults 19 to 64 | At routine visits. Adults 65 and over: evidence insufficient (grade I) | B | USPSTF: Anxiety disorders in adults, screening (2023) |
| Unhealthy alcohol use | Adults 18 and over, including pregnant women | At routine visits | B | USPSTF: Unhealthy alcohol use, screening and counselling (2018) |
| Unhealthy drug use | Adults 18 and over | At routine visits | B | USPSTF: Drug use, illicit, screening (2020) |
| Blood sugar (diabetes) | Adults 35 to 70 with overweight or obesity, and no symptoms | Interval not fixed. USPSTF: every 3 years "may be a reasonable approach" if the first result is normal | B | USPSTF: Prediabetes and type 2 diabetes, screening (2021) |
| Lipid panel (cholesterol) | Adults 20 and over without known heart disease | Every 4 to 6 years. Sooner if risk factors change | Guideline (no USPSTF grade) | ACC/AHA 2018 cholesterol guideline (highlights) |
| Colorectal cancer | Adults 50 to 75 | Colonoscopy every 10 years, or yearly stool test (FIT). Other options are listed in the USPSTF statement | A | USPSTF: Colorectal cancer, screening (2021) |
| Colorectal cancer | Adults 45 to 49 | As for ages 50 to 75. An individual decision with your clinician | B | USPSTF: Colorectal cancer, screening (2021) |
| Breast (mammography) | Women 40 to 74 | Every 2 years. Yearly screening is a decision to make with your clinician | B | USPSTF: Breast cancer, screening (2024) |
| Cervical | Women 21 to 29 | Cytology every 3 years | A | USPSTF: Cervical cancer, screening (2018) |
| Cervical | Women 30 to 65 | Cytology every 3 years, or HPV test every 5 years, or both together every 5 years | A | USPSTF: Cervical cancer, screening (2018) |
| Prostate (PSA) | Men 55 to 69 | Shared decision with your clinician. Any interval is set by the clinician | C | USPSTF: Prostate cancer, screening (2018) |
| Bone density (osteoporosis) | Women 65 and over, and postmenopausal women under 65 with a risk factor | Clinician sets the interval | B | USPSTF: Osteoporosis to prevent fractures, screening (2025) |
For men, the USPSTF finds the evidence insufficient for routine bone density screening (grade I).
USPSTF grades: A and B are recommended. C means decide with your clinician, based on your circumstances. I means the evidence is insufficient to judge. “Guideline” means a professional society recommendation with no USPSTF grade.
This is not general screening. It lists what a prescriber may monitor during treatment. The prescriber sets how often each test is done.
| Treatment | What is monitored |
|---|---|
| Testosterone (men or women) | Total and free testosterone, oestradiol, haematocrit, and PSA for men |
| Oestrogen or progesterone therapy | Oestradiol, progesterone where indicated, and a lipid panel |
| Thyroid replacement (levothyroxine) | TSH, with free T4 where needed |
| Lipid-lowering drug (statin or similar) | Lipid panel, with ApoB where used |
| Diabetes medication | HbA1c |
| Diuretic, ACE inhibitor or ARB | Electrolytes, creatinine and eGFR |
| Prescribed continuous glucose monitor (CGM) | Glucose time in range |
No. It shows what major guidelines recommend for healthy adults in each age and sex group. Whether any of it applies to you depends on your history, your results and what your clinician advises.
The USPSTF recommends mammography every two years for women aged 40 to 74. Yearly screening is a choice to make with a clinician, based on your risk.
The USPSTF gives PSA screening for men aged 55 to 69 a grade C. The benefits and harms are closely balanced, so the choice depends on your values and a conversation with a clinician.
USPSTF grades: A and B are recommended; C means decide with your clinician; I means the evidence is insufficient to judge. "Guideline" means a professional society recommendation with no USPSTF grade.

Chronological age counts birthdays. Biological age estimates how old your body appears to be functioning, based on measurable biomarkers. Two people born the same year can differ by a decade or more in vascular stiffness, insulin signalling or cardiorespiratory fitness. Biological age makes that gap explicit — and unlike your birthday, it can move in either direction.
Each biomarker you enter is scored against longevity-optimised reference ranges and grouped into one of eight dials. Every dial produces its own biological age, and those are combined using fixed weights into a single composite, then expressed as a Longevity Score from 0 to 100. The weighting reflects how strongly each system predicts healthspan: structural and vascular carry the most, hormonal the least.
No. The short form contains a subset of scoring inputs plus context-only fields, and you can leave any of them blank. It is not a recommendation to obtain tests. Missing values are excluded from the calculation — never treated as zero or as 'normal'. A dial with no scored data is dropped entirely and the remaining weights renormalise.
Some inputs can be measured without bloodwork. Blood pressure needs a home cuff and waist-to-height needs a tape measure. Wearable estimates vary; the floor-based sitting-rising test carries a fall risk and should only be attempted if safe.
Both terms describe what this tool does, and which one fits depends on what you are asking. "Anti-aging" is the term most people search, and loosely means anything aimed at slowing or reversing age-related decline — this tool fits that description if you score your dials and act on what you find. "Healthspan calculator" is the more precise term: healthspan is the number of years lived without serious chronic disease or disability, and that cannot be measured directly, so this tool scores eight systems that each function as an early-warning proxy for it. Either way, the method is the same: real biomarkers, published thresholds, no vanity-metric framing.
