SBC PreCheck

Thank you for donating with us today!

SBC preCheck™ is designed to give you a head start on the blood donation process by allowing you to answer many of our blood donation screening questions on your own device before you come in to donate.

PLEASE NOTE: Your SBC preCheck™ questions MUST BE STARTED AND COMPLETED ON THE DAY OF YOUR DONATION. SBC preCheck™ will not tell you whether or not you are eligible to donate blood (this will be determined when you answer the remaining questions at your donation site).
