Glucose in the blood changes every minute, it is a rather unstable indicator, but glycated hemoglobin (on a laboratory form it is sometimes referred to as "glycosylated hemoglobin" or abbreviated HbA1C) is an indicator of long-term compensation of carbohydrate metabolism.
I-glucose esegazini ishintsha njalo ngeminithi, lokhu kuyinkomba engazinzile, kepha i-glycated hemoglobin (kwesinye isikhathi ebizwa ngokuthi yi-"glycosylated hemoglobin" noma i-HbA1C kwelebhu engenalutho) iyinkomba yokubuyelwa isikhathi eside kokudla okwenziwe nge-carbohydrate metabolism.
