Step 1 of 5
How old are you?
Age determines which tests become most valuable and when screening intervals change.

Female
Step 3 of 5
Any specific health concerns or family history?
Select all that apply. These shift which tests get prioritized.
Family history of heart disease or stroke
Family history of cancer
Family history of Alzheimer's or dementia
Pre-diabetes, insulin resistance, or diabetes
Overweight or concerned about body composition
Hormonal concerns (low energy, libido, menopause)
Sleep problems or suspected sleep apnea
None of the above — generally healthy
Step 4 of 5
What testing have you already done?
Select any you have had in the past 12 months. We will not re-recommend tests you have already done.
Basic bloodwork (CBC, CMP, lipid panel)
Advanced panel (ApoB, hs-CRP, insulin, HbA1c)
Hormone panel (testosterone, thyroid, estrogen)
DEXA scan (body composition / bone density)
Coronary Artery Calcium (CAC) score
VO2 max test
Epigenetic / biological age test
Genetic testing (23andMe, AncestryDNA, etc.)
None of the above
Step 5 of 5
How comprehensive should your plan be?
Routine tests are always included, and tests linked to your answers are added at every level.
Essentials only: routine tests and anything your answers call for
Balanced: adds common cardiovascular tests such as ApoB and Lp(a)
Comprehensive: adds situational tests to discuss
Important Disclaimer
This tool provides general educational guidance on longevity-related testing. It is not a substitute for professional medical advice. Testing recommendations should be discussed with your physician, who can evaluate your individual health context, interpret results, and determine clinical appropriateness. Some tests require a physician's order. Insurance coverage varies.

The Evidence-Based Approach to Longevity Testing

Not all tests are equally useful. Some, like a comprehensive metabolic panel and lipid panel, are routine for most adults. Others are useful only in specific circumstances, and some, such as epigenetic age tests, are research tools. This tool helps you see which tests fit your situation.

What makes this tool different

Unlike testing companies that recommend their own products, this tool is unbiased — IQ Healthspan does not sell tests, partner with labs, or receive referral fees. Recommendations are based on the evidence hierarchy: which tests published guidelines support for your age and sex, and which ones your answers suggest discussing with your clinician.

The testing hierarchy for longevity

For most adults, testing follows a clear order. First come routine labs (CBC, CMP, lipid panel and HbA1c). Next, common add-ons such as ApoB, Lp(a) (usually measured once) and hs-CRP can refine cardiovascular risk. Situational tests, including fasting insulin, homocysteine, vitamin D, thyroid and hormone panels, are most useful when your history or symptoms point to them. Imaging, such as a CAC score or a bone density (DEXA) scan, is guided by age, sex and risk, and fitness testing (VO2 max) adds information that bloodwork cannot. Epigenetic clocks are research tools and are not used to guide routine care.

How often to test

Your clinician sets the interval for routine labs. If you make a significant change, such as starting a medication, a repeat test can show its effect. Imaging is repeated only when the result would change a decision, and Lp(a) usually needs testing only once. The most important principle is consistency: a single snapshot is less informative than a trend over time.
