I'm guessing that 2 nanograms represents 2SD or 3SD from the 0.6 value? Can anyone find this study? Given the changes in the food supply in the last 20 years, perhaps this study should have been repeated?
Here's a 2006 article from Ayotte summarizing a lot of this. Old... instruments are more accurate now.
