Carol,

Thanks for responding and for passing on the info. from ithe endo journal.  Do you think that the fact that the first draw was done at 10:30 and the second at 11:45 could have any bearing on the results.  They tried 5 times to get an iv in my youngest daughter and kept blowing the vein.  So finally we went to the lab and they drew then injected then drew again.  I know ideally it should be before 10:00.  Another 180 ng/dl on the 17 ohp and she would fall into the "gray zone".  

My second question is whether or not these results would indicate a high probability of both of my daughters being carriers.  It seems to me that b/c of where their results fall on the nomogram that they probably are.

I was hoping when I posted that you would respond.  Thank you so much for being willing to give your time and knowledge to others.  I appreciate you tremendously.

Best regards.....Lisa
