By no means am I pushing for any sudden renaming of a column.

Before further responding to the "Linguistics-du-jour ...", I wanted to start 
by offering the following, because I found them, particularly the first, 
interesting. The other two go mainly to the idea of "standardization".

1) From Local Laboratory to Standardisation and beyond Applying a common 
grading system

- see esp page 6-7:


For example let’s assume a value of 10 was obtained from local laboratory A 
with a normal range of 5-25, if we want to normalize this value using the 
standard laboratory range, that was established to be 10-35, by applying the 
above formula we would obtain a normalized value of 16.25 as detailed here below

s = 10+ [(10−5) x (35−10) / (25−5)]
   = 16.25


2) Standardizing Laboratory Data by Mapping to LOINC

3) Successful Lab Result Conversion for LAB Analysis Data with Minimum Effort
