Thai medical and health documents — 6 cases

In Thailand a medical certificate may only be issued by a physician licensed by the Medical Council of Thailand, and its content must match what the doctor actually observed on the date of examination. Issuing a certificate that does not reflect the facts is a professional-ethics violation and may carry legal liability, so applicants should not ask a doctor to state more than was examined.

Requirements differ by receiver. Some accept a short statement that no condition preventing work was found; others require named tests such as a chest X-ray or blood work; others supply their own form that the doctor must complete and sign directly. Checking the receiver's form before the appointment avoids a repeat examination.

The International Certificate of Vaccination or Prophylaxis follows the WHO International Health Regulations (2005). Yellow fever is the vaccination the Regulations tie directly to the ICVP form; other vaccinations are recorded in an immunisation booklet or on a facility-issued certificate under national practice.

In practice not every receiver wants an ICVP. Universities and employers in many countries accept a facility document listing the vaccine names, the date of each dose, lot numbers and the provider's signature. Always read the receiver's requirement before preparing documents.

Clinical records are created and retained by the facility under the Sanatorium Act B.E. 2541. The patient does not own the physical record but may request a copy of their own data under the facility's procedure and data-protection law, which means filing a request form and proving identity.

What is actually used abroad is usually not the whole file but a medical report or discharge summary written by the treating physician: the diagnosis, treatment given, current medication and doses, and recommendations for continuing care. It is easier to read and translates more precisely.

A fitness-to-fly certificate may be requested by an airline from passengers with certain conditions — after surgery, in late pregnancy, or when medical equipment is carried on board. The conditions and forms are set by each airline, not by any Thai authority, so read the carrier's policy first.

A fitness-for-work certificate is used in employment, particularly for roles with specific safety standards such as confined-space work, work at height, seafaring, or industries where a foreign employer prescribes a named test panel.

When a death occurs in a healthcare facility, a doctor issues a certificate of death (Thor Ror 4/1) recording the deceased's details and the cause found. This is not the death certificate itself: it supports the death notification to the district registrar under the Civil Registration Act B.E. 2534, which then issues the death certificate (Thor Ror 4).

The two documents serve different functions and receivers differ. Foreign registries and courts usually want the registrar-issued death certificate, while life insurers commonly want both that and the cause-of-death document, so keep both.

A medical claim rests on two halves: the clinical side explaining what happened and how it was treated, and the financial side showing what was paid. Insurers compare both against the policy, so a pack missing one half attracts follow-up requests and delay.

On the financial side receivers usually want the original receipts and an itemised bill separating room, medication, procedure and physician fees. On the clinical side they want the medical certificate and a treatment summary giving the diagnosis and treatment dates.
