Medical certificate Bangkok: An official physician-signed document issued after a same-day consultation, usable for work, visa, work permit, driving licence, school, sports, sick leave, travel and insurance. At our Asoke clinic, a medical certificate in Bangkok is issued within the same visit, in English or Thai, and signed by a registered Thai Medical Council physician. The consultation includes vitals, a symptom review, and any targeted tests the certificate type requires, so the document is clinically valid and not just a rubber stamp.
Clinically reviewed by Dr. Ponlawat Pitsuwan, Physician, Doctor Bangkok Clinic (Asoke / Sukhumvit).
A medical certificate is one of the most common reasons people walk into our Asoke clinic. Some need sick leave for an employer after a 48-hour stomach bug. Others are renewing a work permit and need the Thai Ministry of Labour form. Tourists sometimes need a fit-to-fly letter after an illness, and expats often need an insurance form filled out. The paperwork looks simple, but it matters that the document is issued by a registered physician after a real consultation. An invalid or cut-corner certificate causes more problems later, especially for immigration and insurance, than the twenty minutes it takes to do it properly.
Types of medical certificate we issue in Bangkok
The format of the certificate depends on what it is for. A sick leave certificate confirms you were medically unfit for work on specific dates and is usually one page. A work permit certificate in Thailand uses the official Ministry of Labour template and declares you are free from leprosy, tuberculosis, drug addiction, chronic alcoholism, third-stage syphilis and elephantiasis, which is why it requires a specific physician examination. A visa medical follows whichever format the destination country or embassy requires, which may include additional blood work and chest X-ray. A driving licence certificate in Thailand uses the Department of Land Transport format and confirms colour vision, general fitness and no disqualifying conditions.
School and sports certificates usually confirm fitness to participate in physical activity or return after an illness or injury. Fit-to-fly letters certify that you are medically stable enough to board a commercial flight, and airlines will often specify the wording they need (for example post-pregnancy, post-surgery, or recent illness). Insurance forms vary hugely, from a short claim note to a detailed medical report, and we charge based on the complexity of the form.

What to bring to your appointment
To issue a medical certificate in Bangkok quickly and correctly, bring a valid passport or Thai national ID, any blank forms the employer, embassy, school or insurer has given you, and a list of current medications. For a work permit certificate, bring your old work permit and, if this is a renewal, your previous certificate. For a visa medical, know exactly which country and visa category you are applying for, because requirements differ. For a fit-to-fly letter, bring the airline’s form or tell us the carrier and the flight details, because airlines have different cut-offs (for example pregnancy over 36 weeks). If the certificate is for a return to work after an accident or surgery, bring any discharge summary or imaging you have.
When a medical certificate is not enough and you need a proper assessment
See a doctor if: you are requesting a sick leave certificate but are still actively unwell with fever, ongoing vomiting, severe pain, breathing difficulty, confusion, chest pain or any red-flag symptom. The certificate can still be issued, but the priority is to treat the underlying condition first. A certificate without treatment is a wasted visit. Please tell reception you are unwell so we book you as a clinical consultation, not just a paperwork slot.
A medical certificate is also not a way to bypass a real assessment. If you are unfit for work, we need to document why. If you are unfit to fly, we need to know the reason so the airline can accept the letter. If the certificate is for a work permit and we find something clinically significant during the examination, we will discuss it with you and arrange further testing rather than ignore it. This is the difference between a physician-issued certificate and a stamp from a walk-in shop: the document is only useful if it is honest.
Prevention and early detection: the visit is also a chance to screen
Prevention point: A medical certificate appointment is often the only time a healthy adult sees a doctor all year. Use it. If you are in the clinic for a work permit or visa medical, take the opportunity to check your blood pressure, update your vaccinations, and discuss anything that has been on your mind. It costs very little to add a basic wellness screen to the same visit and can pick up hypertension, diabetes or high cholesterol before they become a problem.
For adults over 35, we recommend combining the annual work permit medical with a basic health check up in Bangkok every year, and a full screen every 2 years. Travellers collecting a visa medical should also review their vaccinations at the same time, particularly tetanus (Tdap every 10 years), hepatitis A and B, typhoid for longer trips, and rabies pre-exposure if travelling to rural areas. A single 30-minute visit can cover the certificate, the vaccinations, and the screening conversation.
Summary
A medical certificate in Bangkok from our Asoke clinic is issued the same day, in English or Thai, by a registered Thai Medical Council physician. We cover sick leave, work permits, visas, driving licences, school and sports, fit-to-fly and insurance forms. Bring your ID, any blank forms and your medication list, and allow roughly 30 minutes for a standard certificate and up to 60 minutes for one that includes blood tests or imaging. The consultation is the point: the certificate is only the paperwork that comes out of it.
“People sometimes apologise for coming in just for a certificate, but I think it is one of the most useful visits we do. It is often the only chance I get to screen a busy adult and say, while you are here, let us also check your blood pressure.” — Dr. Ponlawat Pitsuwan, Physician, Doctor Bangkok Clinic
Frequently asked questions
How much does a medical certificate in Bangkok cost?
A standard sick leave or simple fitness certificate is modestly priced and includes the consultation. Work permit, visa medicals and any certificate that requires blood tests or a chest X-ray are priced higher because of the additional investigations. We confirm the total cost before you commit so there are no surprises. Contact the clinic directly for current rates.
Can I get a medical certificate in English?
Yes. We issue certificates in English, Thai or both, depending on who needs it. Work permit and driving licence certificates use the official Thai template, but we add an English translation where useful. Visa medicals are typically issued in English.
Do I need an appointment or can I walk in?
Walk-ins are welcome for standard certificates. For work permit medicals, visa medicals and anything that requires blood tests or imaging we recommend booking ahead so we can prepare the right forms and schedule the lab. Evening and weekend appointments are available.
Can a medical certificate be backdated?
A certificate can document an illness that started earlier if the clinical history supports it, but the examination and signature date will always be the date of the actual visit. We cannot issue a document that implies you were examined on a day you were not, because it would not be a valid certificate.
Is the medical certificate valid internationally?
A certificate from a registered Thai Medical Council physician is recognised internationally for most purposes, including embassy visa applications, employer sick leave, airline fit-to-fly and travel insurance. For some formal immigration medicals a country-specific panel physician is required, and we will refer you to the correct centre if that is the case.
Can I combine a medical certificate with a health check up?
Yes, and we encourage it. If you are already in the clinic for a work permit or visa medical, adding a basic wellness screen takes only a few minutes extra and the results are available the same day or within 24 hours. This is an efficient way to get both pieces of paperwork and a proper screen in a single visit.
