which might be able to be populated from any of a variety of sources:
Oxford University Press:

UCSD Lab Medicine
http://ucsdlabmed.wikidot.com/chapter-0
NIH Endocrinology Expected Values & S.I. Unit Conversion Tables

University of California, San Francisco
http://labmed.ucsf.edu/sfghlab/test/ReferenceRanges.html
and there is also this calculator (maybe even easiest to parse?):
