Co je to HbA1c?

Hemoglobin A1c (HbA1c) is a form of hemoglobin that carries glucose atated to it transfegh a non enzymatic reaction. Red blood cells circulate for approquatele 120 days, so the estage of glycated hemoglobin reflects the average blood glucose concentration over the preceding two two thre e months. Unlike a fingstick glucose reading, which captures a single moment, HbA1c offers a váhated evee that gives clincians and patients a reliable picture of long term glycemic control.

Why HbA1c Is Central to Diabetes Care

Long Român Term Indicator of Glycemic Control

Daily self authmonitoring of blood glucose (SMBG) or continuous glucose monitoring (CGM) provides valuable reail atime data, but each measurement is just a snapshot. HbA1c fills a different role: it integrates all the highs and lows over many weess, giving a summay that cannot bee influmenced by a single high hadrophydrate meal or an afnoon of exterise.

For instance, if a patient 's HbA1c rises estate the credit range dessite a good diet and fyzical activity plan, a provider may add or adjust oral agents (eg., metformin, SGLT2 consiors, GLP concertor 1 receptor agonists) or insulin terapy.

How HbA1c Is Measured and Reported

The Blood Teset

Te HbA1c tett implices a small venous or capillary blood sampare. No fasting is necessary, making it compleent for routine check check 'ups. Te sampare is analyzed in a laboratory using high gh g.efficience liquid chromatogray (HPLC), immunoassasy, or enzymatic methods.

Standardization and Certification

To ensure consistency and classiy, the National Glycohemoglobin Standardization Program (NGSP) certifies laboratories. Te NGSP sets thee reference methode (DCCT creditaligned) and allows traceability to the IFCC reference method. when reviewing tett results, it is important to confirm that that te labolaboratory is NGSP completifified, as non grentified labs may produce less reliable value value.
