Clinical Guide to Services - "C" Tests
The Clinical Guide to Services is a comprehensive reference guide of testing services, shipping information and submission requirements. Efforts have been made to be concise and current with all information, but as testing procedures and regulations change, some information may not be current. Many of these tests are only available with prior approval from MDH. It is impossible to address all situations in this guide, so please contact us with any questions.
