In the States I believe the units used are ng/dl thats nanograms per desilitre nano is 10 to the power of -9 or one billionth. In Canada the unit is mol or mole measured in pmol or pico moles think pico is 10 to the power of -12 or 1 trillionth,(pretty friggin minute). The 1000 figure would be high end in the ng/dl measure. High normal? I wish that were my results... I think it is the high end, but I don't think that means high average.
