Wyo. Stat. Ann. § 27-11-113

Any employer may require an employee to submit to a physical examination before employment or at any time during employment, and shall provide for a physical examination, as deemed necessary, due to exposure or contact with hazards or environmental conditions which may be detrimental to the health of the employee. Nothing in this or any other provision of this act shall be deemed to authorize or require medical examination, immunization or treatment for those who object thereto on religious grounds, except where such is necessary for the protection of the health or safety of others. The results of such examinations shall be furnished only to the department, the employer and, upon request, to the employee and the employee's physician. The employer shall pay for such examination.
