You can “test yourself” for health in two complementary ways: simple self-checks you can do at home regularly, and structured medical/online tests that give more objective data. Both work best when combined with periodic visits to a clinician rather than used as a replacement.

1. Easy self-checks you can do regularly

These do not require kits and are useful as a baseline between formal checkups.

Daily/weekly basics

• Weight and waist circumference

  • Track weight once a week under similar conditions.
  • Measure waist at belly button level; a larger waist is linked to higher risk of metabolic and heart disease (risk thresholds differ by sex and ethnicity).

• Resting heart rate and blood pressure

  • Use an automatic home BP cuff; measure seated, after 5 minutes rest, arm at heart level.
  • Keep a log of blood pressure and pulse; rising trends over weeks matter more than a single reading.

• Energy, sleep, and mood

  • Ask yourself weekly: “Am I more tired than usual? Sleeping well? Feeling down or anxious most days?”
  • Persistent changes over 2+ weeks warrant a conversation with a professional.

• Physical capacity (very rough fitness screen)
  If safe for you:

  • Can you walk briskly for 10 minutes without getting unusually winded?
  • Can you climb 1–2 flights of stairs without stopping?
    Declines over months are often an early sign of health problems.

• Self-exams

  • Skin: look monthly for new or changing moles or lesions.
  • Breasts/chest or testicles: notice new lumps, changes in size, or pain.
    Any new or growing lump, bleeding, or persistent change → see a clinician.

2. At‑home medical tests (physical health)

These are kits you buy online or at a pharmacy; you collect a sample at home and either read the result yourself or mail it to a lab.12

Types of at‑home tests

• Self-tests (you do the test and read result at home)
  Examples: pregnancy tests, some blood glucose, some COVID‑19 tests.1
• Self-collection tests (you collect sample, mail to lab, get results later).1

Common categories of at‑home tests:

• Blood sugar / diabetes risk

  • Finger‑stick glucose meters and A1C tests monitor or screen for diabetes.110
  • Useful if you have risk factors (overweight, family history, hypertension, etc.), but abnormal results must be confirmed by a lab and interpreted by a clinician.

• Cholesterol and heart‑related panels

  • Some services and kits let you order lipid panels and broader heart‑health tests without first seeing a doctor, then go to a lab draw or use a mail‑in kit.68
  • Good for tracking, but “normal” ranges and treatment decisions should be reviewed with a professional.

• Kidney, liver, thyroid, vitamins, hormones

  • Direct‑to‑consumer companies (Quest, Labcorp, Testing.com partners) offer broad panels for metabolic, thyroid, vitamin D, sex hormones, etc.678
  • Best used to complement—not replace—regular care, because interpretation is nuanced.

• Infections / STIs / UTIs

  • At‑home tests for COVID‑19, HIV, some STIs, UTIs, and others use urine, swabs, or blood drops.110
  • Positive or unclear results should be followed by confirmatory testing and medical advice.

• Colon cancer screening

  • Fecal occult blood tests (FOBT/FIT): you collect stool samples on a card or container and mail them to a lab to check for blood, which can signal colon cancer or other problems.110

• Pregnancy and fertility

  • Urine pregnancy tests (self‑tests) using first morning urine are highly sensitive.1
  • Ovulation and some fertility hormone tests are also available, often as self‑collection kits.

How to use at‑home medical tests safely

• Choose only FDA‑approved/authorized tests; regulators impose quality standards on these products.12
• Follow instructions exactly, including timing and sample amount; small deviations can change results.12
• Never use expired kits.1
• Do not change or stop medications based solely on at‑home results; consult your clinician first.12
• If results are surprising, unclear, or don’t match how you feel, contact a professional for advice.2

3. Mental health self‑tests

Mental health is a major part of overall health.

• Organizations like Mental Health America offer free, confidential online screening tools for depression, anxiety, bipolar disorder, and more.3
• These tools ask symptom questions and estimate whether your pattern is consistent with a common mental health condition; they are screeners, not diagnoses.3
• Use them to decide whether to seek counseling, therapy, or medical evaluation.

4. Lifestyle and behavior self‑assessments

Your habits often say more about health risk than one lab test.

• Healthy lifestyle questionnaires ask about diet, exercise, sleep, substances, and stress; you get a score and feedback on areas to improve.5
• These tools can highlight:
  • Low fruit/vegetable intake
  • Sedentary behavior
  • High stress and poor coping strategies
  • Problematic alcohol or substance use

Again, they guide self‑reflection; they are not medical diagnoses.

5. More advanced “how healthy am I?” screens

If you want deeper objective data (often used by athletes or people very focused on prevention), common options include:9

• VO₂ max testing – measures maximal oxygen use during exercise; strong indicator of cardiovascular fitness.9
• DEXA scan – measures body fat %, lean mass, and bone density in detail.9
• Coronary artery calcium (CAC) score – CT scan that measures calcium in coronary arteries to refine heart‑disease risk estimates.9
• Genetic testing – at‑home DNA tests analyze limited sets of variants for disease risk and ancestry.49

Most of these should be ordered or at least interpreted with a clinician because they can significantly affect management and often have important limitations.49

6. How to put this together into a personal plan

You can combine self‑checks and tests into a simple routine:

1. Daily–weekly

   • Track weight, basic activity (steps or minutes walked), sleep duration, and mood.

2. Monthly

   • Blood pressure at home (several readings over a week).
   • Brief mental‑health screener if mood or stress seems off.3
   • Skin and self‑exams.

3. Every 6–12 months (or as advised by a clinician)

   • Bloodwork for cholesterol, glucose/A1C, kidney, liver, thyroid, as appropriate for your age and risk; this can be via your doctor or reputable direct‑access labs.678
   • Lifestyle questionnaire to see progress in diet, exercise, sleep, stress.5

4. When you have symptoms

   • Use appropriate at‑home tests (e.g., COVID‑19, UTI, stool blood, pregnancy) to guide whether to seek care sooner.110
   • Always follow up if symptoms persist or tests are positive or confusing.12

7. Important cautions

• At‑home tests are tools, not replacements for professional care.12
• A normal test does not guarantee absence of disease; a single abnormal result does not always mean you are sick. Context and repetition matter.
• For genetic and advanced imaging tests in particular, professional interpretation is crucial to avoid unnecessary worry or over‑treatment.49

If you tell me your age, sex, and any key concerns (weight, heart, mental health, fertility, etc.), I can outline a more tailored “self‑testing + checkup” schedule.
