Colon (Intestine)

Your colon (large intestine) removes water, salt, and nutrients, while forming stool. It is coated by billions of bacteria that live in a healthy balance with your body. When this balance is off, the complete colonic environment can be altered, opening the door for metabolism issues, yeast growth, impaired immunity, and even cancer. Manage your gut health by understanding it. Order from a suite of Walk-In Lab online tests to understand the health of your colon and your entire body. Thank you for browsing our selection of Colon/Intestine blood tests and panels. Shop additional Digestive System Tests confidentially and order online without insurance or a doctor's note.
