Medical certificate format: what a genuine certificate includes

1. Pick the certificate type you want to understand: sick leave, fitness, sports fitness, fit to fly, return to work, or general health for a visa.
2. Tap or click each numbered marker on the preview to read what that field means and why it is there.
3. Choose a country to see a short note from our maintained data and the date we last checked it.
4. Read the field table under the preview if you prefer a plain list.
5. Download the watermarked PDF or PNG if you want to keep the reference. It is a sample for learning, not a usable certificate.

Formats vary by country, by purpose and by who asks for the certificate. A sick leave note for an employer looks different from a health certificate for a visa. Still, most share the same building blocks.

This library shows those building blocks for six common certificate types. Each preview is annotated so you can see what each field is for. The previews are generic teaching samples. They are not copies of any official national form.

Where an official form exists, we point you to the government guidance that describes it. The UK fit note is the clearest public example, so we use it often below.

Here is what each building block does.

• Patient identity. This links the certificate to one person. It is usually a name and sometimes a date of birth.
• Date of assessment. This tells the reader when the clinician actually assessed you. It can differ from the date the certificate was written.
• Condition or reason. This states the health problem in words the reader can act on. Some forms allow a less specific description to protect the patient.
• Fitness statement. This is the core opinion. For work, it might be "not fit for work" or "may be fit for work" with changes.
• Advice or comments. This explains what the person can do, or what changes would help.
• Period covered. These are the dates the opinion applies to.
• Follow up. This says whether the clinician needs to see you again before the end date.
• Issuer details. This is the name, profession and practice address of the person who issued it, plus a signature or an equivalent digital authorisation.
• Date of issue. This is when the certificate was produced.

The UK fit note guidance for clinicians lists the official boxes in this order. Box 1 is the assessment date. Box 2 is the condition. Box 3 holds the fitness options. Box 4 holds comments, and those comments are mandatory when "may be fit for work" is ticked. Box 5 is the period. Box 6 is the follow up, which is mandatory. Boxes 7 and 8 are the issuer's name and profession. Box 9 holds the date of the statement and the practice address. Box 10 is the signature on the older paper template.

A few more official points help you read a UK fit note correctly.

• A new version of the form was introduced on 6 April 2022. Older versions can still be used.
• Since 1 July 2022, doctors, nurses, occupational therapists, pharmacists and physiotherapists can certify fit notes.
• Employees can self certify for the first 7 calendar days of sickness absence.
• Fit notes can be handwritten, printed from a computer, or sent digitally.
• There is no option on the fit note to sign someone back to work.

The UK employer checklist says a fit note is not valid unless the issuer's name, profession and practice address are completed. The employer guidance adds that a note with no signature and no issuer name should not be accepted, as it may not be genuine.

Here are sensible checks for any certificate, in any country.

1. Look for complete issuer details. Name, profession and practice address should all be present.
2. Check the dates make sense. The assessment date, issue date and period covered should form a logical order.
3. Read the fitness statement. It should say clearly what the clinician concluded.
4. Look for a verification route. UK guidance notes that printed or digital fit notes may include a barcode that can be scanned. Certificates from getmedicalcertificate.com carry a reference code anyone can check.
5. Check for "duplicate" markings. UK guidance says a duplicate must be clearly marked "duplicate" and issued only if the original was lost.
6. Ask, if unsure. UK guidance says an employer can write to the healthcare professional for more information, though there may be a charge and a delay.

A certificate is a piece of evidence, not a verdict. The UK guidance describes the fit note as advisory, and says the employer can decide whether to accept it.

The preview labels the fitness statement, the advice box and the period covered. In the UK, the period box has a maximum of 3 months during the first 6 months of a condition.

In Ireland, a GP issues a "Certificate of incapacity for work" for an Illness Benefit claim. Citizens Information says some GPs can complete it online. The doctor must mark the last certificate as final before you return to work.

For statutory sick pay in Ireland, Citizens Information says you must be certified by a medical practitioner as unable to work.

The key fields are the purpose named on the certificate and the scope of the opinion. A good fitness certificate says what it covers and does not stretch beyond that.

The annotated preview highlights the sport or level named, the examination date and the validity period. Our sports fitness certificate is valid for 12 months. Check your club's rules with our sports club certificate requirements tool.

We have not found a single public standard for this document that we could verify. So the preview shows common building blocks only: the condition, the planned travel date, any special assistance, and issuer details. Always check your airline's medical page before you book.

UK government guidance for clinicians says people do not need to be signed back to work, and there is no option on the fit note to do this. It also says a patient can go back to work whenever they feel able, without a new fit note.

Where an employer still asks, a return to work format typically records the date you can resume and any recommended changes, such as altered duties. The preview labels these fields.

For example, the UK TB test page says applicants from listed countries test at an approved clinic. If no TB is found, you receive a certificate. It is valid for 6 months from the date of your chest x ray, and you include it with your visa application.

At a global level, the WHO says the International Health Regulations (2005) cover health documents for international travellers. They apply to 197 countries, including all 194 WHO Member States. One known example is the yellow fever certificate. The third edition of the IHR made it valid for the life of the person vaccinated.

Here is how the manager reads it.

• Issuer details. Name, profession and practice address are present. The checklist test for validity is met.
• Dates. The issue date (3 March) is one day after the assessment date (2 March). Official guidance says these can differ, so this is fine.
• Period. 2 March to 30 March is 29 days. That is well within the 3 month maximum for the first 6 months of a condition.
• Comments. "May be fit for work" is ticked, so Box 4 must be filled in. It is.
• Follow up. Box 6 says reassessment is needed. The manager should expect a further note if the employee is still unwell after 30 March.

The manager then talks with the employee about seated work. If the workplace cannot offer it, UK guidance says the note is treated as "not fit for work". The employee does not need a new note to say so.

The fields that make a certificate genuine are the issuer's name, profession, address, signature or digital authorisation, and any verification code. Those only mean something when a real clinician has assessed a real patient. So our samples show where these appear and explain them in words, but never draw them as fields to fill.

Our files come as flattened PDF and PNG. You cannot edit them as text. We do not offer a word processor version.

If you need a certificate for a real purpose, a clinician has to assess you. See the section below on how we can help.

• People use it to understand what they will receive and to check nothing obvious is missing.
• Employers and HR teams use it to train managers on what to look for. The UK employer guidance says you can keep a copy of a fit note, while the employee keeps the original. It also says the employee's information must be kept confidential.
• Schools, colleges and clubs use it to set clear, fair expectations for students and members. Each one decides which certificates it accepts.

If you write a policy for your organisation, refer to the official guidance for your country. Do not rely on a sample layout as the rule.

Each certificate costs EUR 34.99 with no added fees at checkout. You pay only after a doctor has reviewed your case, and you get a full refund if the doctor cannot issue it. The doctor decides in every case.

Approved certificates arrive as a signed PDF, usually within about 30 minutes of approval. Each carries a reference code anyone can check. We issue in English, German, French, Spanish, Italian, Polish and Dutch across 42 European countries.
