<P>I want to bring it up with the kids doctor when ew go back in July. Lillian is 7, and Jack is 5. Are they too young? They typically do pretty well with ivs and blood draws, but there is no way of knowing before hand how well they will do.</P>

<P>Does this test typically give a def. answer? My kids have one mutation and many symptoms, but carry a dx of CRMS. </P>
