I remember reading on this board months ago that children's 17 OHP levels were off. The parents thought that it was because of residue that would not mix in the Cortef. Does anyone who remembers this know if they ever stated what lot number was imprinted on the boxes? I've been giving my child liquid Cortef for years and this is the first time I've seen it. I am of course thinking of switching to the pill but in any case please let me know what the lot number is. thanks alot! Linda
