Which countries accept the antibody test with medical certificate?

Question from Ger: What legal value does a medical certificate have?
Which countries accept them and which do not?
And can it be reordered in the event of a positive antibody test result?

Answer: Unfortunately, we have been informed by the Ministry of Health that a serological antibody test does not count as proof of a contracted disease, the reason being that they do not know how long it has been since you had COVID-19.

In the Netherlands, only a PCR test performed by a Municipal Health Service (GGD) less than six months ago is considered proof of a contracted disease.

We cannot comment on the ever-changing access policies of the various countries.
You can always reorder the medical certificate if you want, should you feel more confident doing so. We will transfer the costs to the doctor who will make an additional assessment of the results.
