Occupational Medicine

Occupational Medicine at UP Health System works for employers to include all aspects of the relationship between workplace factors and health. This includes physical, chemical, biological, social, and psychological aspects. A specific and individualized program is developed to fit each client's needs.

Occupational medicine specialists evaluate and treat workplace injuries and illnesses, and render opinions as to the work-relatedness of a medical condition. Services include work-related physical examinations, surveillance exams required by the OSHA/MIOSHA Department of Transportation exams, urine drug, and breath alcohol testing services, and fitness-for-duty evaluations (work restrictions). Occupational medicine specialists also provide appropriate referrals.

If you are an FMCSA covered driver having diabetes mellitus (DM) requiring insulin for treatment, you must present with the MCSA-5870 form completed in its entirety by your treating physician/clinician. This form requires you to have maintained at least the preceding three months of ongoing blood glucose self-monitoring records that are measured with an electronic glucometer that stores all readings, records the date and time of readings, and from which data can be electronically downloaded. We strongly urge you to review the FMCSA website for further direction. The rules provide for a possible one-time maximum three-month certification to gain such compliance. The rules also reference an HGA1c in the three months prior to certification.
