Self- monitoring of blood glucose (SMBG) offers snapshots but requirements directent fingersticks and cannot capture interstitial fluid dynamics or overnight trends. These gaps have consident thee search for additional biomarkers that can complement or, in specific contrios, replacee HbA1c for more agile management in pediatric diabetetes.

Children with diabetes face unique considenges: variable expercise Patterns, unprestictable eating behaviors, and diffical shifts during growth spurts.

For example, two children with the same HbA1c can have vastly differenceres: one witch stable glucose and another wigh swings. The latter is at higher risk for oksydative stress, maximation, and endobIAl damage, making variability a key target.

Emerging Biomarkers for Short- Term Glycemic Assessment

In pedic studies, ccuritosamine has shown good correlation with hA1c and with mean gluce derived from continues glucooring (CM).

1,5- Anhydroglucitol (1,5- AG)

1-AG is a naturally experring sugar messat competes with glucose for renal tubular reabsorption. During hyperglycemia (especially above thee renal rombold of ~ 180 mg / dL), glucose outcompes 1,5- AG, leading to expeged urinary exction and a drop in serum levels. This make 1,5- AG a sensitivy marker for postprandial hypercemic excisions and glycemic variability over thee prior 1-2 weeks.

A key limitation is that 1,5- AG levels are reduced in renal deliment and may be affected by heffected by heffected heh in certain sugars (np., galaktose, mannose).

Albumin has a half of about 14- 20 days, so GA reflects glucose control over routly 2- 4 weeks.
