Annual health check: what to test at 20 / 30 / 40 / 50+
The tests that matter at each age from your 20s to 50+, based on standard screening guidance, and how to choose between our Plan A, B and C.
Health check packages are sold on the number of tests, and the more there are, the better the deal looks. The tests worth doing are for conditions likely at your age, where finding them would change your care. Below is what standard screening guidance recommends for each age group, matched to the clinic's Plan A, B and C.
Key takeaways
- At every age: blood pressure, weight and BMI, and a review of risk factors with a doctor at least once a year.
- Basic blood tests (sugar, lipids, liver, kidney, blood count, urine) become clearly useful from 30–35, or earlier if you have risk factors.
- From 40 add HbA1c and a heart-risk assessment. From 50 add bowel cancer screening and sex-specific checks.
- Plan A (1,290 baht) suits 20–35 with no risk factors, Plan B (2,490 baht) suits 35–50, and Plan C (3,290 baht) is for people whose doctor thinks tumour markers are worth adding.
How to think about screening
A useful screening test passes three tests: the condition is reasonably common at your age, finding it before symptoms changes the outcome, and the test does not do more harm than good, for example through false positives that lead to unnecessary further tests. International guidance therefore does not recommend tumour markers for people without risk factors, even though many packages include them.
More important than age is your personal risk: family history of diabetes, heart disease or cancer at a young age, excess weight, smoking, alcohol and existing conditions. If any apply, start the next age group's tests earlier.
Ages 20–29: establish your baseline
- Blood pressure every year. High readings at this age are more common than you'd think and usually silent
- Weight, height, BMI and waist circumference
- A lipid profile at least once in this decade to know your baseline, especially with a family history of high cholesterol or heart disease
- A complete blood count (CBC) once, to screen for anaemia and thalassaemia carrier status, which matters before planning a pregnancy
- Review adult vaccines: yearly flu, a tetanus booster every 10 years, and the HPV vaccine if you've never had it
Good to know: Without risk factors you don't need a full blood panel every year at this age; every 2–3 years is enough. But seeing a doctor for blood pressure and a lifestyle chat should still be yearly.
Ages 30–39: start screening for chronic disease properly
- Everything from your 20s plus a basic panel once a year: fasting blood sugar (FBS), full lipid profile, liver and kidney function, uric acid and urinalysis
- Thai guidance recommends diabetes screening for adults from 35, or earlier if you're overweight with other risk factors
- Women from 30: cervical screening with an HPV DNA test every 5 years (covered by the universal health scheme) and regular breast self-examination
- A hepatitis B test at least once if you've never had one. Thais born before 1992 weren't vaccinated at birth and may be carriers without knowing
Ages 40–49: assess heart and diabetes risk in detail
- Yearly basic panel plus HbA1c for a three-month picture, especially if FBS is edging into the at-risk range (100–125 mg/dL)
- Have the doctor calculate your 10-year cardiovascular risk from age, sex, blood pressure, lipids, smoking and diabetes, to decide on lifestyle changes or medication
- Women from 40: consider a mammogram on your doctor's advice, especially with a family history
- Eyesight and eye pressure: start periodic eye checks, especially with diabetes or a family history of glaucoma
- Vaccines: flu every year, and plan the shingles vaccine when you reach 50
Age 50 and over: add evidence-based cancer screening
- Yearly basic panel and HbA1c, with closer monitoring of kidney function (eGFR)
- Bowel cancer screening: a faecal immunochemical test (FIT) every year, or colonoscopy as advised. The universal scheme covers FIT from 50 to 70
- Men: discuss PSA testing with your doctor. It has both benefits and limits and should be a shared decision, not automatic
- Women: mammogram every 1–2 years, continue cervical screening to 65, and assess bone density after the menopause according to risk
- Vaccines for this age: flu every year, shingles, and at 60–65 add pneumococcal and RSV. Read which vaccines seniors need
Matching the clinic's plans to your age
| Plan | Key tests | Best for | Price |
|---|---|---|---|
| Plan A | FBS, lipids, liver, kidney, CBC, urine, uric acid + physical exam by the doctor | Ages 20–35 with no risk factors, or pre-employment | 1,290 baht |
| Plan B | Everything in A + HbA1c, blood group, hepatitis B and C | Ages 35–50, diabetes risk, or never tested for hepatitis | 2,490 baht |
| Plan C | The basics + tumour markers for liver, bowel, ovary (women) or prostate (men) | People with a specific risk identified by the doctor, such as hepatitis B carriers or a family history | 3,290 baht |
Choose Plan C when you and the doctor agree that tumour markers are useful in your case, not because it has the most tests. Read why tumour markers aren't a screening test for everyone, and see the full comparison table on the health check page.
Good to know: If you already have a condition such as diabetes or high blood pressure, follow-up testing differs from general screening. See chronic condition care.
Before you come
Sugar and lipid tests usually need 8–12 hours of fasting; HbA1c and CBC do not. See how to fast before a health check, and once you have results, how to read your blood test results.
Frequently asked questions
See a doctor yearly for blood pressure and a risk review. A full blood panel every 2–3 years is enough without risk factors. Plan A is a good starting point.
