Ordering a SIBO Test

Ordering process

Bring this brochure to your doctor.

Your doctor will determine if SIBO testing is appropriate for you. If you need help finding a doctor, please call the NCNM Clinic for a consultation with one of our staff physicians. We must have an order from a doctor to give you a test kit.

Your doctor can place the order by:

Phone: 503.552.1980
Fax: 503.257.5929

Once the order is placed, call the lab to arrange a time to pick up the kit. If you live outside the Portland metro area, the kit  can be shipped to you. If you do not feel comfortable collecting the samples at home, you may schedule collection in our lab by a trained professional.

How much does the test cost?

Option 1: $155 to pick up the kit for home collection.
Option 2: $180 to do the procedure in our lab.


All kits must be paid for in advance. If you choose to pick up your kit at the NCNM Clinic you can pay when you pick it up. Otherwise your provider will have you fill out a form including shipping address and payment information. You will also have the option to fill out a courtesy billing form for your insurance*. Your provider will then fax the form to the NCNM Sibo Center where payment will be collected and your kit will be shipped.

*Payment can be made by credit card (Visa, MasterCard, Discover) or by check, along with any accompanying insurance information. Please note that the courtesy billing form must accompany the original order, all kits are charged for in advance, and a refund is issued when the insurance payment reconciles.

Returning your SIBO Kit to the Lab

When you have finished collecting your samples you may either:

  1. Bring the completed kit to the NCNM Lab anytime the clinic is open (see hours)
  2. Ship the kit to us at 3025 SW Corbett Avenue, Portland, OR 97201
