Donating Blood: What to Expect
Donating blood will take approximately 45 minutes for the entire process.
It is important that you are well prepared for your donation. Eat a well-balanced meal and drink plenty of non-caffeinated fluids, such as water or juice.
Step 1: Registration
You will be asked to provide some basic information (name, address, age, etc.). A photo ID is required to donate (student ID, driver’s license, passport). In addition, you will answer approximately 50 questions related to your medical history and lifestyle. The questionnaire will be provided at the time of your donation.

Step 2: Medical History and Mini-Physical
One of our qualified staff will review your medical history with you. A finger prick to insure your hemoglobin is high enough for you to donate; then your pulse, blood pressure and temperature are checked.
Step 3: Blood Donation
A nurse or phlebotomist will cleanse and sterilize your arm before inserting a needle. The needle is sterile, used only once and then disposed. After 7 to 10 minutes, your donation should be complete.
Step 4: Rest and Refreshments
Relax and enjoy water, fruit juices, cookies and assorted snacks after your donation for at least 15 minutes.
