Three countries,three different standards
Spain assesses from your medical history alone. Greece requires supporting test evidence. Thailand uses its own Embassy form and a list of five named conditions.
Spain — a declaration
A statement citing the International Health Regulations 2005, drawn from a review of your medical history. No blood tests, no X-rays. Apostille and sworn Spanish translation are required.
Spain requirementsGreece — evidence required
The Embassy's own standard form under Law 4251/2014, supported by evidence of your TB status and a negative syphilis blood test. The most involved of the three.
Greece requirementsThailand — five named conditions
The Royal Thai Embassy form under Ministerial Regulation No. 14, confirming freedom from five specific conditions. Requires notarisation rather than apostille.

Comparingrequirements
Which countries currently require a Medical Certificate of Good Health?
Of the destinations we serve, Spain and Greece require one as part of the long-stay visa application, and Thailand requires its own Embassy form for long-stay categories. Many other countries satisfy the same public health objective through private health insurance or post-arrival screening instead, so a certificate is not universally needed. Always check the documentation list published by the consulate handling your application.
Do I need a certificate for a short stay?
No. The requirement applies to long-stay national visas — generally any stay beyond 90 days. Short-stay Schengen visits to Spain or Greece, and tourist entry to Thailand, do not require a medical certificate.
Why does Greece ask for tests when Spain does not?
The two countries frame the requirement differently. Spain asks the doctor to declare that the applicant is free from diseases with serious public health repercussions under IHR 2005, which is assessed from medical history. Greek law additionally requires the certificate to address other infectious, contagious and parasitic diseases, and in practice this means supporting evidence on tuberculosis and syphilis. Greece also specifies its own certificate form rather than accepting a letter.
Can one certificate be used for two countries?
Not usually. Each certificate is prepared to the wording and format the receiving consulate expects, and Greece and Thailand both use their own forms. If you are applying to more than one country, you will need a separate certificate for each.
My consulate has given me its own form. Can you complete it?
Yes, and we would prefer you send it to us. Where a consulate supplies a specific document, that version takes precedence over any general template. Forward it when you order and our doctor will complete that form.
What is an apostille, and do I always need one?
An apostille is a certificate issued by the FCDO confirming that a UK document carries a genuine signature, so that authorities in another Hague Convention country will accept it. Spain requires it. Thailand asks instead for notarisation by a notary or the diplomatic mission. For Greece, confirm the position with the Consulate handling your application.
Does the certificate need translating?
Spanish applications generally require a sworn Spanish translation of the apostilled certificate. Thai applications do not usually require translation. Both apostille legalisation and sworn translation are arranged through our partner, The Apostille Service, rather than by us.
How far in advance should I order?
For Spain, four to six weeks before your consulate appointment allows time for both the certificate and the apostille while staying inside the 90-day validity window. For Greece, allow longer, since you will need to arrange TB evidence and a syphilis blood test first. Greek documents are also generally expected to be dated within one month of submission.
Can my own NHS GP issue the certificate instead?
Your GP can write a letter, but apostille legalisation requires a signature from a doctor registered with the FCDO — a separate registration from the GMC that most NHS practices do not hold. Our doctors hold both, so your certificate can be legalised and submitted without difficulty.
