I am trying to get an idea of how my son's 17-ohp results compare with some of the other children's on the board, but I am having a hard time doing that as it appears we use a different unit of measure in Canada. His result was 5.9 nmol/L. Reading some of the other posts on this board, people are talking about there childrens results being in the 200+ range. How does this compare with that? Does anyone know? Thanks.
