Hi All,

Can you please provide feedback on an existing concept in SNOMED CT: 259689004 | Glycosylated hemoglobin (substance)?

This concept has a synonym of "Glycated hemoglobin". Although the terms seem to be used interchangeably, there appears to be inconsistency in their usage. We believe that they are not synonymous and that we need three separate concepts to represent Glycated hemoglobin, Glycosylated hemoglobin, and HgA1c (possibly as a child for Glycated hemoglobin?).

We identified issues for the terms that use this concept in their modelling. Some example are as following:
Glucohemoglobin measurement (procedure) | SCTID: 40402000 seems to be misspelled and we are not sure if it is needed as a grouper. Perhaps it is an order?
Glucose measurement estimated from glycated hemoglobin (procedure) - SCTID: 117346004 doesn’t seem to have the correct modelling

There are a few other concepts that might be affected; e.g. concepts containing HgA1c.

We would appreciate your input on this.

Best regards,

Farzaneh
