Medical certificate in Koh Samui
Official medical certificates for work, insurance, visa, diving or travel, issued the same day by a licensed English-speaking doctor. Fast, professional service at our walk-in clinic in Bang Rak, minutes from Samui Airport and the Big Buddha.
When you need a doctor’s signature on Koh Samui
Plenty of everyday situations on the island call for a medical certificate. Your employer back home wants proof of the days you were unwell in your hotel. Your travel insurer will not process a claim without a proper medical report. Thai immigration or the transport office asks for a health certificate for a visa, work permit or driving licence, or your dive school needs written confirmation that you are fit to go underwater. Whatever the reason, a medical certificate in Koh Samui must be issued by a licensed physician after a genuine examination, and that is exactly what our clinic in Bang Rak provides, usually within a single short visit.
Certificates we issue the same day
Our English-speaking doctors examine you and provide the official document you need, printed on clinic letterhead with the physician’s licence number in the format Thai authorities, employers and insurers expect.
- Sick leave certificates for employers, schools and universities covering the days you were genuinely unwell
- Insurance medical reports with diagnosis and treatment details to support a travel insurance claim
- Health certificates for Thai paperwork, including visa applications, work permits and driving licences
- Fitness certificates for diving courses, gyms and races, with a physical examination and blood tests when required
- Fit to fly certificates for airlines after illness, injury or during pregnancy
How the process works
No appointment is needed. Walk in any day of the week, as we are open daily with a doctor on call 24 hours for urgent cases. A licensed doctor takes your history, performs the examination and runs any supporting tests in our on-site laboratory if the certificate requires them. The document is then printed, signed and stamped before you leave, and we can also provide a copy by email. Most certificates are ready within thirty to sixty minutes, so there is minimal waiting. If you are too unwell to travel, our doctor can visit your hotel or villa anywhere on the island and issue the certificate on the spot.
Costs, insurance and coverage across the island
You will receive a clear price before the doctor begins, and the fee depends on the type of certificate and whether lab tests are needed, with no hidden extras. If your visit is for an illness or injury covered by your policy, we offer direct billing with most travel insurers, so in many cases you pay nothing out of pocket. We serve tourists, expats and long-stay visitors across Chaweng, Bang Rak and Bophut, and our team can confirm in advance what a specific employer, airline or insurer will accept.
A real examination, not just a stamp
A certificate is only as credible as the clinic behind it. Ours are issued by licensed Thai doctors after a proper consultation, which is why they are accepted by airlines, insurers and government offices. It also means that if the examination uncovers something that needs treatment, you are already in the right place, with a pharmacy and laboratory under the same roof. One important note: if you have chest pain, difficulty breathing, severe bleeding or any other emergency symptom, do not come in for paperwork; go to the nearest hospital emergency department immediately. For everything else, we will have you examined, documented and on your way quickly.
Frequently Asked Questions
How quickly can I get a medical certificate?
In most cases the same day, often within thirty to sixty minutes of walking in. The doctor examines you, runs any required tests and issues the signed, stamped certificate before you leave. If lab results are needed, timing depends on the test, and our team will tell you what to expect.
Do I need an appointment?
No. We are a walk-in clinic in Bang Rak, open daily, with a doctor on call 24 hours. Simply come in with your identification and any details the certificate requires. You are welcome to message or call ahead if you want to confirm requirements first.
Is the certificate accepted by insurers and authorities?
Yes. Our certificates are issued by licensed Thai doctors after a genuine examination, on official clinic letterhead with the physician’s licence number. This is the format airlines, travel insurers, employers and Thai government offices expect and accept.
Can you issue a sick leave certificate for my employer?
Yes. If you were genuinely unwell, the doctor will examine you, confirm your condition and issue a sick leave certificate stating the relevant dates. This is commonly used by travellers who need to explain missed work or study days to an employer or university back home.
Do you provide fit to fly and diving certificates?
Yes. We issue fit to fly certificates for airlines after illness, injury or during pregnancy, and fitness certificates for diving courses. Diving and some activities may need a physical examination and blood tests, which we can perform in our on-site laboratory during the same visit.
Can a doctor come to my hotel to issue one?
Yes. If you are too unwell to travel, our doctor makes hotel and villa visits across Koh Samui, including Chaweng, Bang Rak and Bophut, and can examine you and issue the certificate on the spot. This is ideal when you need documentation but should be resting.
How much does a medical certificate cost?
You will be given a clear price before the doctor begins. The fee depends on the type of certificate and whether any lab tests are required, and there are no hidden extras. If your visit relates to a covered illness or injury, we can often bill your travel insurer directly.
Can I get the certificate in English?
Yes. Our doctors are English-speaking and we issue certificates and medical reports in English, which is what most international employers, airlines and insurers require. If you also need a specific format or additional wording, let us know when you arrive and we will do our best to accommodate it.
