The medical examinations provided for in this sub-section are :
1° At the expense of the establishment when it has an independent occupational health and prevention service or when it is linked by agreement to a service shared by several administrations. The establishment provides the occupational physician with the means to ensure that the examinations remain anonymous. Insofar as these examinations cannot be carried out in the establishment, the occupational health physician chooses the body responsible for carrying them out;
2° At the expense of the inter-company occupational health and prevention service when the establishment uses this structure, unless otherwise stipulated in the agreement signed with the inter-company occupational health and prevention service.
