The purpose of the drive is to see if you can help Ethan Powell, a 4-month-old from Shreveport who has leukemia. The testing normally costs $45. Read more about that in Mary Jimenez's story from the other day.
It's easy, and you just might help save a little boy's life. Granted you should be willing to actually donate the marrow (which is a surgical procedure) if you get tested and added to the national list. They'll contact you if you are ever a match for someone on a local waiting list.
Anyway, I finished the whole testing process in about 15 minutes. It's open until 7 p.m. Here's how you do it:
Fill out your donation papers (and watch a short video).
Swab the inside of your mouth with four Q-tip-like objects.
