When Teddy Oh was 18 months old, his mother and father, Won and Jin, knew something was not right. Teddy had had a persistent cough, and though his doctors did not think much of it at first, the cough was quickly compounded with additional symptoms, principally lethargy and distention of his stomach. A week after his symptoms had progressed, the family went back for a re-check with his pediatrician and was told immediately to take Teddy to the Lucile Packard Children’s Hospital Stanford (LPCHS) emergency room.

After running blood tests, doctors determined that Teddy’s white cells were highly elevated and that his platelets were particularly low.

FAQ on Novel Coronavirus and Blood Donation

Blood Donation: How it Works

Preparing to donate

Before your appointment:

  • Always be sure to drink plenty of water before donating blood!
  • Eat an iron-rich meal. Eating enough iron is essential to ensuring that your hemoglobin level is right for donating. You can check out some tips on getting enough iron here.
  • Bring your donor ID. If you have a donor ID, be sure to bring it with you to your appointment. First-time donors or returning donors without a donor ID card should bring a valid state-issued photo identification.

Avoid alcohol and fatty foods for 24 hours, and aspirin (if donating platelets) for 48 hours, before your donation.

Where does my blood go?

Learn about the life of blood through a new donor’s eye.

It’s my first time donating blood. I walk into Stanford Blood Center (SBC) and I don’t know what to expect. I am a bit nervous because I’m not a big fan of needles, but I know I’m doing this for a good cause. I am greeted by the front desk staff and registered as a new donor with SBC. After completing a brief questionnaire about my health, lifestyle, and recent travel, I sit down with a technician who goes over the blood donation process with me.
