[QUOTE="Grateful, post: 1601662, member: 438800"] This applies to HbA1C: "Officially, there is worldwide consensus that HbA1c should be reported in both NGSP (%) and IFCC (mmol/mol) units along with eAG (in either mmol/L or mg/dL). However, the decision on what to report is actually being made country by country. In the US, reporting NGSP % HbA1c along with eAG has been recommended by the ADA and the AACC. Some other countries have also decided, most will report IFCC and NGSP and some will switch to IFCC only in two years. Although the world will again be reporting different numbers, results will be traceable to IFCC numbers as well as to clinical data through linear equations that are carefully monitored. The ADA, IDF, EASD, and ISPAD as well as other member associations in different countries currently provide patient care guidelines that relate directly to NGSP (DCCT/UKPDS) numbers. These will need to be updated to include both NGSP and IFCC numbers." Source: [URL]http://www.ngsp.org/docs/IFCCstd.pdf[/URL]. That report was issued some years back. I am in the USA and here it does seem that the older system (NGSP) is still prevalent, even if the ADA recommended reporting both numbers. Too bad -- it would be better if all countries routinely used the same units, presumably the newer IFCC scale. It is not unusual for the USA to go its own way with units.
