hi entreat. need to be careful if you are looking at overseas sites, as they measure it differently. i made that mistake at first. the level you have been quoted is in nmol/ml.

the range of 9 - 47 is relevant for ng/ml.

1 ng/ml = 3.18 nmol/ml.

therefore you need to convert.

so a "normal" range is 29 - 149. if that makes sense. i think 30 is where support is generally initiated, just to be safe.

i hope i am getting it right, i researched this for ages when i was having my own panic attack and finding conflicting information.
