The Clinical Guide to Services, from Minnesota’s Infectious Disease Laboratory
The Clinical Guide to Services is a comprehensive reference guide of testing services, shipping information, and submission requirements for Minnesota’s Infectious Disease Laboratory.
Even though there are ongoing efforts to keep information current, some information may not be up to date due to recent changes in testing procedures and/or regulation. Many of these tests are only available with prior approval from the Minnesota Department of Health.
If you cannot find what you are looking for in the guide, please Contact the Infectious Disease Laboratory.
