As a medical courier-independent contractor, your duties focus on the transport and delivery of medical documents, records, lab specimens, test results, medical supplies, and medications. As an independent contractor, you work on a contract basis rather than as a full-time employee. A medical courier’s responsibilities include maintaining documentation, ensuring patient confidentiality, and recording chain of custody. You may transport between a hospital or clinic and a testing facility or medication supplier. Medical couriers may need to follow proper handling procedures when they carry items such as specimens or stem cells.
