Based on the medical examination findings, a medical certificate shall be issued to a seafarer by the medical examiner and must be signed by both the medical examiner and examinee.

The period of validity of the medical certificate will remain in force for a maximum period of two years from the date on which it is granted, unless the seafarer is under the age of 18, in which case the maximum period of validity is one year.

If the medical examiner imposes restrictions on work (i.e., the job the seafarer will Perform, the trade area, time-limit, etc.). these restrictions should be reflected on the Certificate.

If the examinee is found temporarily or permanently unfit for service, he or she should be given an explanation of the reasons and advised on the right and the procedures for making an appeal.

if an examinee is found temporarily unfit, the medical examiner should give advice on the need to make additional tests, to obtain opinions from specialists, to complete dental or other treatment, rehabilitation and/or appropriate medical care. The examinee should be informed of when to return for another examination.

Medical certificates which expire during the course of a voyage will continue to be in force until the next port of call where the seafarer can obtain a medical certificate from a medical practitioner recognized by the party, provided that the period does not exceed three months.
