A medical certificate is considered an official document issued by a physician who holds a valid license to practice medicine from the Medical Council.
To confirm a person’s health status or medical condition, a medical certificate serves as evidence or proof of medical situations and is often necessary for various purposes. In a medical certificate, important information is included, such as the patient’s name, date of birth, diagnosis, treatment details, and the issuing physician’s personal information. Medical certificates are commonly used for sick leave at work or school, health insurance claims, school or job applications, and legal purposes. They provide credibility and report individual medical situations, facilitating appropriate actions according to the person’s objectives.

How many Types of Medical Certificates are there?
Medical Certificate for 5 Diseases
It is a document to verify the condition of the patient, known as the ‘Medical Certificate for 5 Diseases.’ This is because in the past, before the year 2008, there were several major diseases that required physicians to specify and diagnose, including tuberculosis, elephantiasis, chronic alcoholism, diseases caused by substance abuse, and other serious diseases. However, the Medical Council has recently made changes so that only 3 diseases are included in the certificate. This is to confirm that the patient does not have clear symptoms that hinder their daily life or pose a risk of transmitting the disease to others.
Medical Certificate for Sick Leave
It is a document used to show the employer or relevant institution in the case of an employee, student, or learner who is sick with a fever. The physician will specify the details of the patient’s condition based on the actual diagnosis and will not provide false or exaggerated information. This is considered a violation of medical ethics. The Department of Welfare and Labor Protection stipulates that employees should present a medical certificate to the employer if their sick leave exceeds 3 days.
Medical Certificate for Driving License Examination
It is a document used for the purpose of applying for all types of driver’s licenses, including driving license examination, obtaining a new driver’s license, renewing a driver’s license, and changing the type of driver’s license. The applicant for this medical certificate must undergo verification that they do not have any diseases that affect their driving ability, such as mental illness, epilepsy, elephantiasis, chronic alcoholism, physical disabilities, drug addiction, contagious diseases, including tuberculosis, and other relevant medical history related to driving. The medical certificate for driver’s license examination or renewal is valid for 30 days from the date of application.
Medical Certificate for School Enrollment, Job Application and Education.
It is a document used for school enrollment and job application to verify the health of students and job applicants, confirming that they do not have diseases that could affect their studies, work, or transmit infections to students, colleagues, teachers, employers, or customers. Depending on each profession or organization, there may be different requirements, such as screening for sexually transmitted diseases, tuberculosis, symptoms of drug addiction, chronic alcoholism, elephantiasis, major heart conditions, pneumothorax, asthma, lung diseases, epilepsy, muscular dystrophy, cerebrovascular diseases, and other serious illnesses that may impact learning or work performance. It is advisable to inquire with the respective organization regarding the specific requirements for obtaining a medical certificate.
Medical Certificate for a Work Permit
It is a document certifying that the person has undergone a genuine health examination according to the specified requirements, in order to apply for a Work Permit, which is the work permit for foreign nationals who will work as employees in Thailand. This document is used in conjunction with the passport and visa. The doctor will conduct an examination, take medical history, measure blood pressure, heart rate, weight, and height. They may perform a chest X-ray and heart examination, check for substance abuse, and conduct a blood test. Afterward, they will state that the person does not have the following diseases: sexually transmitted diseases, infectious tuberculosis, drug addiction, chronic alcoholism, elephantiasis, blistering skin diseases, syphilis, and other serious illnesses that may impede work performance. This type of medical certificate has a validity period of 60 days from the date of application.
