Hemoglobinopathies And The A1C Test

The a1c test can be used to diagnose type 2 diabetes and prediabetes. 1 the a1c test is also the primary test used for diabetes management. an a1c test is a blood test that reflects your average blood glucose levels over the past 3 months. the a1c test is sometimes called the hemoglobin a1c, hba1c, glycated hemoglobin, or glycohemoglobin test.. Fourth, the a1c test is very well standardized and trusted due to its nearly universal use. a variety of more advanced forms of the a1c test (e.g. some types of hplc, immunoassay and capillary electrophoresis) can more accurately assay a1c levels during complex hemoglobinopathies and other conditions.. Factors that affect interpretation of hba1c results: any condition that shortens erythrocyte survival or decreases mean erythrocyte age (e.g., recovery from acute blood loss, hemolytic anemia) will falsely lower hba1c test results regardless of the assay method used [2]. hba1c results from patients with hbss, hbcc, and hbsc must be interpreted.

The most common hemoglobin variants that can affect a1c test results are hemoglobin s, c, d, and e. 2 these variants can also cause hemoglobinopathies, a group of blood disorders and diseases that affect red blood cells.. A hemoglobin abnormality is a variant form of hemoglobin that is often inherited and may cause a blood disorder (hemoglobinopathy).hemoglobin is the iron-containing protein compound within red blood cells that carries oxygen throughout the body.. 2. nathan dm, kuenen j, borg r, et al: translating the a1c assay into estimated average glucose values. diabetes care. 2008 aug;31:1473-1478. 3. american diabetes association, classification and diagnosis of diabetes: standards of medical care in diabetes. diabetes care. 2018; jan;41:s1. 4. national academy of clinical biochemistry. hb a1c..

Glycated hemoglobin (glycohemoglobin, hba1c, hemoglobin a1c, a1c, or less commonly hba 1c, hgba1c, hb1c, etc.) is a form of hemoglobin (hb) that is chemically linked to a sugar. most monosaccharides, including glucose, galactose and fructose, spontaneously (i.e. non-enzymatically) bond with hemoglobin, when present in the bloodstream of humans.however, glucose is less likely to do so than.

It is also valuable to assess hyperglycemia, a history of hyperglycemia or dangerous hypoglycemia. glycated protein testing may be used in place of glycated hemoglobin in the management of diabetic patients, and is particularly useful in patients who have abnormalities of erythrocytes such as hemolytic anemia or hemoglobinopathies. limitations.
