@ling Please keep us posted should you decide to move forward with the study. I reviewed my notes and at the time of reading the consent form I decided it wasn't for me because of the # of blood draws required. I really don't like getting lab draws. I work hard to combine them among my doctors to cut down on the # of sticks! Unfortunately these draws cannot be used for annual checkups etc. Apparently the blood is sent off to a lab that's helping conduct the study.
