We took part in this study without the use of core blood. It was pretty easy. They sent us paper work to fill out, then all of us in the family sent in blood samples.

That was the fun part...not... our youngest daughter did not do well with the blood draw (she screamed the whole time ) We sent the blood back by Fed Ex and for quite a long time everytime Brittany saw the Fed Ex truck she would say that that was the truck that took our blood
