After or during a visit to one of UNM Health’s many clinics, you may require some blood work to be performed. Your physician or nurse ordering the test will help guide you to the nearest TriCore Laboratories clinic for your work to be done. TriCore is a unique, non-profit clinical reference lab, which is co-sponsored by the UNM Health Sciences Center.When blood work is ordered for your medical care, your physician and nurses will carefully explain the procedure and why the test is ordered. Some tests will be simple and be able to be completed immediately. Others may require you to fast for a certain time before your test. Be sure to ask your physician any question you may have if you are unsure about any step of the process.
