Actually, 13 ng/ml would be equal to 1300 ng/dl, so as Dalton’s Mom said, the 17 OHP would be slightly on the high side.  Not too bad, though.

If Daltons’ blood pressure is high, it probably means that his florinef dose needs to be adjusted.  According to my son’s peds. endo, babies generally get anywhere between 1/2 a pill once a day (0.05 mg) to a full pill 2-3 times a day (up to 0.3 mg).  With such a wide range of requirements among different patients, it probably means that you just need to "tweak" and "adjust" the dosage, till you achieve the amount that is right for Dalton.

Good luck!
