Which blood tests should you choose for a health check-up in Chiang Mai?
How blood tests for a health check-up are actually chosen — why there is no single panel that suits everyone, what commonly gets included and why, and how a fixed package differs from individual assessment.
Quick answer
There is no single blood-test package that suits everyone. Which tests are worth doing depends on your age, symptoms, personal and family history, existing conditions, medicines, pregnancy, lifestyle, and what you have had checked before. A short conversation before testing usually produces a more useful set of results than choosing the largest available package — more tests are not automatically better, and unnecessary tests can generate borderline findings that cause worry without changing anything. Klaibaan Medical Clinic in San Sai provides consultation, testing, and doctor review of results. Walk-ins are welcome, and consultation with sample collection can usually be completed during the same visit.
Why there is no universal panel
It is tempting to treat blood testing as a product to be bought in the largest available size. In practice, the value of a test depends on the likelihood that it will find something meaningful in the person being tested.
A test that is genuinely useful for a 60-year-old with a family history of heart disease may add nothing for a healthy 25-year-old. And every test carries a small chance of a borderline result that turns out to mean nothing — which can lead to repeat tests, further investigation, and anxiety without any benefit. That is the real argument against reflexively choosing the biggest panel.
The opposite mistake is also common: choosing a minimal package that omits something genuinely relevant to your situation. This is why a short discussion beforehand is worth the few minutes it takes.
What influences which tests are appropriate
- Age: the conditions worth screening for shift as people get older
- Symptoms: fatigue, weight change, thirst, breathlessness, or other symptoms direct testing toward specific answers
- Existing conditions: diabetes, hypertension, kidney, liver, or thyroid conditions each imply their own monitoring
- Medicines: some require periodic kidney or liver monitoring
- Family history: early heart disease, diabetes, or certain other conditions in close relatives can bring testing forward
- Previous results: a borderline result last time may deserve a repeat this time
- Pregnancy or planned pregnancy: changes both what is relevant and how results are interpreted
- Lifestyle and occupation: including alcohol, smoking, and specific exposures
- Documentation requirements: some work permits, visas, or employers specify particular tests
Bringing previous results is particularly valuable. A single value in isolation says less than the same value seen as part of a trend.
Common categories and what they are for
Rather than prescribing a universal list, it is more useful to understand what the common categories are for:
- Blood count: looks at red cells, white cells, and platelets — relevant to anaemia, signs of infection, and other general findings
- Blood glucose or HbA1c: assesses blood sugar; HbA1c reflects the longer-term picture rather than a single moment
- Lipid profile: cholesterol fractions and triglycerides, used in assessing cardiovascular risk
- Kidney function: relevant with diabetes, high blood pressure, certain medicines, or a family history of kidney disease
- Liver-related tests: relevant with alcohol use, certain medicines, viral hepatitis risk, or metabolic conditions
- Thyroid testing: considered where symptoms or history suggest it
- Other tests based on individual risk: including hepatitis screening, uric acid, urine testing, or infection-related testing, guided by your situation
Which of these apply to you is exactly the conversation worth having before the sample is taken.
Packages versus individual assessment
Fixed packages have real advantages: they are simple, the price is clear in advance, and they cover common ground reasonably well. For a broadly healthy person with no particular concerns, a sensible standard package is often a reasonable starting point.
Their limitation is that they are designed for an average person who does not exist. A package may include tests that add little for you while omitting one that matters given your history — which is why a brief discussion beforehand is worthwhile even when a package is ultimately chosen. Adjusting a standard set is usually straightforward.
How testing works and how results are handled
Some tests can be performed rapidly, and some samples are sent to an external laboratory — so how quickly results are available depends on which tests are done. The doctor will tell you what to expect for your particular set.
Results are reviewed and explained by a doctor rather than simply handed over. This matters because interpretation depends on context: a value slightly outside a reference range is not automatically abnormal, and a value within range is not automatically reassuring if it has changed substantially from your previous result.
Depending on what is found, the next step might be no action at all, a repeat test after an interval, a change in diet or activity, treatment, further testing, or referral for additional evaluation. Where a result relates to an ongoing condition, it feeds into regular follow-up — see our guide on continuing chronic-disease care in Chiang Mai.
What to bring
A short written note of what you actually want to know is more useful than it sounds. "I am tired all the time" or "my father had a heart attack at 55" shapes test selection more effectively than a request for a general check.

Frequently asked questions
Is there a standard blood-test package everyone should have?
No. Which tests are worth doing depends on your age, symptoms, personal and family history, existing conditions, medicines, pregnancy, lifestyle, and what you have had checked before. A fixed package is a reasonable starting point for a broadly healthy person, but it is designed for an average that does not describe any particular individual — a short discussion beforehand usually improves the result.
Are more tests always better?
No. Every test carries a small chance of a borderline result that turns out to mean nothing, which can lead to repeat testing, further investigation, and worry without benefit. The value of a test depends on how likely it is to find something meaningful in the person being tested, which is why selection matters more than quantity.
What are the common categories of blood test used in a check-up?
Commonly used categories include blood count, blood glucose or HbA1c, a lipid profile, kidney function, liver-related tests, thyroid testing where symptoms or history suggest it, and other tests based on individual risk such as hepatitis screening, uric acid, or urine testing. Which of these apply depends on your situation.
How long do results take?
It depends on the test. Some tests can be performed rapidly, while some samples are sent to an external laboratory. The doctor will tell you what to expect for the particular set of tests you have, and results are reviewed and explained rather than simply handed over.
Do I need to fast, and can I check beforehand?
Some tests require fasting and many do not, so it depends on which tests are planned. You can confirm what applies to you by LINE or telephone before coming. Our separate guide on preparing for a blood test covers fasting and related practical questions in more detail.
