LOINC display name : HbA1c Elph (Bld) [Mass fraction];
LOINC long common name : Hemoglobin A1c/Hemoglobin.total in Blood by Electrophoresis;
LOINC short name : HbA1c MFr Bld Elph;
LOINC description : Changing from the property from Mass fraction to substance fraction has not effect
on the meaning when the molecular weight of the numerator and the denominator are
the same (for practical purposes). These terms had had a property of MFR in the past
and we changed to SFR because we thought the LOINC community preferred SFR for HbA1c.
But we mis understood the preference is to use the MFR variant- so we have changed
back.;
