Providers, please complete the both sections of the form below, then click “Submit”. You will receive a confirmation email after your information has been successfully submitted. We will create your account after your credentials have been validated, which is usually within one business day. We will then send a laboratory requisition to the email address you list below that you will fax to us with each SIBO test ordered. Important: Please note that two substrates are available in the at-home SIBO kits: lactulose and glucose. Because lactulose is regulated by the FDA as a legend drug, it is only available to the public with a prescription from a licensed health care provider. Please check with your local state licensing board to determine if you have prescriptive rights for legend drugs before registering if you plan to prescribe SIBO test kits that contain lactulose as the substrate.
