componentHydrogen/Expired gas^2H post XXX challenge
    2H  =  2 hours post challenge
propertyVFr  =  Volume Fraction
timePt  =  Point in time:  To identify measures at a point in time. This is a synonym for “spot” or “random” as applied to urine measurements.
systemExhl gas  =  Exhaled gas (breath)
scaleQn  =  Quantitative:  The result of the test is a numeric value that relates to a continuous numeric scale. Reported either as an integer, a ratio, a real number, or a range.
