Medical couriers deliver medical equipment to patients and health care providers as well as blood and other specimens to medical laboratories for testing. Some medical couriers carry donor organs around the country to hospitals with patients awaiting transplants.  Medical couriers are important contributors to the health industry. On-time deliveries help doctors give the right diagnoses to their patients.  Medical couriers need to make their deliveries in a certain amount of time, usually specified by the medical provider, to make sure the specimen doesn’t degrade.

The basic task of a lab courier is to shuttle between medical testing facilities and the hospitals and offices that have ordered the tests. Many clinics and other medical facilities do not have adequate staff or equipment to run the full range of tests and imaging that are currently available; instead, these facilities contract out medical testing to independent companies that operate diagnostic labs. Couriers pick up and deliver samples and specimens for testing, using a fixed schedule that brings them to their stops at about the same time every day

The pick-up and delivery of medical records, test results, images, specimens and pharmaceuticals among labs, clinics, hospitals and medical offices is the job of a lab courier. The job requires couriers to have  flexibility, reliability, organization and a good knowledge of the local street and interstate system.
