Blood tests in Chiang Mai
Klaibaan Medical Clinic in San Sai offers walk-in blood-test collection for a specific requested test, symptom-based assessment, routine screening, or follow-up of an abnormal result. Fasting is required only for certain tests. Some specialised samples go to an external laboratory, so reporting time depends on the test. The doctor reviews results in clinical context rather than interpreting one number alone.
- Common options include CBC, glucose or HbA1c, cholesterol, liver and kidney function, and other tests when appropriate.
- Ask before coming if you are unsure whether to fast.
- Some reviewed results can be sent by LINE after identity confirmation.

Common blood-test categories
You may need one specific test or a focused group—not every test listed below.
Blood cells
CBC may help assess anaemia, infection patterns, platelets, or follow-up of a known blood abnormality.
Glucose
Fasting glucose or HbA1c may be used for diabetes screening or follow-up; they answer different questions.
Cholesterol
Lipid testing can support cardiovascular-risk assessment and medication follow-up.
Liver and kidney
Tests may be selected for symptoms, medication monitoring, chronic disease, or previous abnormal results.
Other focused tests
Thyroid, iron, vitamins, hormones, infection-related tests, and other specialised tests are selected when clinically relevant.
Choosing the right tests for you
Blood tests are most useful when matched to your symptoms, age, risk factors, and reason for checking. The doctor can help you choose clinically relevant tests so the results are practical and understandable.
During the visit, the doctor reviews why you need testing, whether fasting is required, and which results need follow-up. After the results are available, we help explain what they mean in context and whether repeat testing, treatment, or referral is needed.
When a blood test may be useful
- A specific test your doctor or another clinic recommended
- Fatigue or pale appearance
- Blood sugar, cholesterol, liver, or kidney follow-up
- Review of previous abnormal results
- Documents or certificates that require lab results
Getting your results
Some blood test results can be sent by LINE after identity confirmation and clinic review. If a result needs explanation, the doctor may advise a follow-up discussion.
Do I need to fast?
Not every test requires fasting. Some glucose or lipid tests may need 8–12 hours of fasting. Please ask the clinic before coming so you arrive prepared and avoid a repeat visit.
Frequently asked questions
Do I need to fast before a blood test?
It depends on the test. Some glucose or lipid tests may require fasting, while many other tests do not. Please contact the clinic before coming if unsure.
Can blood test results be sent by LINE?
Yes — some results can be sent through LINE after identity confirmation and clinic review. The team will advise what is appropriate for your specific test.
Can I choose my own tests?
You can ask about specific tests. The doctor may recommend a suitable set based on your symptoms, age, risk factors, and the reason for checking, rather than ordering everything at once.
Can I walk in for a blood test?
Yes. Walk-ins are welcome during opening hours. Contacting the clinic first is useful if you need a specialised test, are unsure about fasting, or have a deadline for a document or result.
