This perhaps requires growing these columns (upper, lower, alpha_range) into 
the test_type table.

I suppose that a lab may alter its normal ranges over time. Therefore we should 
still store, with each patient measurement, the normal range (if any) that was 
in effect at the time of the test result being generated.
