Thank you, Chair, and thank you to the panel.
Dr. Fourney, I wonder if you could answer the first part and perhaps Mr. Bird or Mr. Yost could answer the second part of my question.
The first part would be so that people understand what it means to have a sample for your purposes, a sample taken from an individual. I'm wondering if you could explain to everybody here what that really means. Is it taking of saliva, blood, whatever?
