Functional Lab Testing in Green Bay, WI
Your labs came back normal. So why do you still feel off?
If you've been told your bloodwork looks fine but you're still tired, bloated, foggy, or just not yourself, you're not imagining it. A standard lab panel is a good starting point, but it doesn't always show the full picture of how your body is working.
Functional lab testing looks deeper. At Wagner Integrative Health in De Pere, we use functional testing to better understand your hormones, gut health, metabolism, and possible environmental exposures like mold and heavy metals. Then our providers use those results to build a plan that fits you.
The medical industry is exploding with different ways to test our bodies. While standard labs at your primary care doctor’s office are valuable, functional lab tests dive deeper into the inner workings of your body and help to identify the weak links that may be preventing you from reaching your health goals. Functional labs tests encompass various areas, including gut health, hormone balance, metabolism and toxin detection such as mold and heavy metals. At Wagner Integrative Health, we use a personalized approach to decide which tests are right for you. Experience the power of advanced functional lab testing at Wagner Integrative Health.
Is functional lab testing right for you?
Functional testing may be worth a conversation if you've been dealing with any of these and haven't found clear answers:
Fatigue that doesn't improve with rest
Bloating, constipation, loose stools, or reflux
Brain fog or trouble concentrating
Hormone changes, irregular cycles, or low libido
Weight that won't budge despite your efforts
Trouble falling or staying asleep
Ongoing joint pain, headaches, or skin flare-ups
Symptoms that started after a tick bite or time in a water-damaged building
How is functional lab testing different from standard labs?
Standard labs, like the panels ordered at a yearly physical, check whether your results fall inside a reference range. That's useful for catching disease, but the ranges are wide, and a routine panel leaves out many markers. You can land inside the range and still feel far from your best.
Functional lab testing takes a broader and more detailed look. Depending on your symptoms and history, that may mean measuring hormones at several points across the day, looking at the bacteria in your gut, or checking for exposures to mold or heavy metals. Some tests use blood, while others use saliva, urine, stool, or breath.
The goal isn't more testing for its own sake. It's finding the reasons behind your symptoms so your care plan can address them.

How does functional lab testing work at Wagner Integrative Health?
Individualized consultation. Your first visit starts with a conversation about your symptoms, health history, lifestyle, and goals. This helps your provider choose the tests that make sense for you, rather than ordering everything.
Simple sample collection. Depending on the test, we may draw blood in our lab here in De Pere, or send you home with an easy collection kit for saliva, urine, stool, or breath.
A results review with your provider. You won't be left to decode a page of numbers. Your provider walks you through your results, explains what they mean, and connects them to how you've been feeling.
A personalized plan. From there, we build a plan around your results. That may include nutrition, supplements, lifestyle changes, or other therapies we offer, with follow-up to track your progress.
“Dr Wagner and her team were wonderful to work with. They take the time to work with you and get to the root causes of your symptoms. I thought being tired and having breakouts was due to hormones fluctuating after having kids however she helped me figure out it was actually my gut. I feel so much better now and have more energy to not only care for myself but my family too.”
