Laboratory

The Gundersen Health System Laboratory is committed to excellence by providing quality service with integrity, efficiency and compassion.

Our Laboratory is a vital component to providing safe quality healthcare. We provide diagnostic and treatment information for patients throughout our 19-county service area.

All our medical clinics provide laboratory services for patients of all ages.

Many lab test results can be viewed through Gundersen's free, secure online patient portal, MyCare more quickly than if we mail them to you. If you'd like more information about MyCare, would like to sign up, learn how to download the app so you can access MyCare on your mobile phone, or find the forms to authorize access for your child's or dependent's records, go to MyCare Information.
