Become A Donor | Patients suffering from Clostridium difficile infection need your help.

Become a Donor

We need your help, but more importantly, patients suffering from Clostridium difficile infection need your help. When you can see past the unique nature of the donation, you will see that it is very safe, scientific and extremely helpful in saving and improving the lives of countless patients.

You can expect to receive personal attention to help guide you through the donation process. It starts with a confidential medical history review by one of our licensed staff members, followed by a blood draw for infectious disease testing and then a clean, private facility for the donation.

Our donation center is located at 10520 Armstrong Avenue, Suite B, Mather, CA 95655.

To become a donor or for more information, please call (844) 426-7264 or email
