Hemoglobinopathies And The A1C Test

Because the a1c test is based on normal hemoglobin, hemoglobinopathies can affect the reliability of the test 10 in three ways: 1) altering the normal process of glycation of hba to a1c, 2) causing an abnormal peak on chromatography, making estimation of a1c unreliable, and 3) making the red blood cell more prone to hemolysis, thereby decreasing the time for glycosylation to occur and producing a falsely low a1c result. 11 therefore, although hbas is not a disease, when a person with hbas. Our investigation confirms that a1c underperforms as a diagnostic test for hyperglycemic states even in the absence of nutritional deficiencies or hemoglobinopathies. therefore, we agree that while controversy exists in the diagnostic efficacy of a1c overall, as a single test in africans, a1c is not an optimal substitute for the ogtt ( 11 , 24 , 31 , 32 ).. Hemoglobinopathies are frequently linked to artifactually altered hemoglobin a1c (hba1c) concentrations. 5 in blacks with prediabetes, the presence of the hemoglobin s variant is associated with a higher hba1c concentration and this elevation is not an artifact. 6 blacks compared to non-hispanic whites (nhws) tend to have a higher hba1c concentration for the same degree of glycemia as measured by glycated serum proteins (known as fructosamine) or blood glucose. 7 this discordance is known as.

On this page: what is the a1c test? how does the a1c test work? can the a1c test be used to diagnose type 2 diabetes and prediabetes? why should a person be tested. short description: hemoglobinopathies nec. icd-9-cm 282.7 is a billable medical code that can be used to indicate a diagnosis on a reimbursement claim, however, 282.7.. Hemoglobinopathies may distort hba1c – a caution to practitioners. measuring glycated hemoglobin (hba1c) gives us a patient’s long term average blood glucose levels. 1 since hba1c measures the percentage of patients’ glycosolated hemoglobin, patients who possess variants of hemoglobin can exhibit false readings.. Web of science. they report that approximately 14% of laboratories are using assays with significant interference with hb variants.</p>the american diabetes association does not recommend the use of hba1c as a screening tool for diabetes. however, if an a1c test is performed on a person not known to have diabetes and an elevated level is found,….

Hemoglobinopathy and interference with a1c assessment. a1c represents the main fraction of hemoglobin bound to glucose (glycohemoglobin) and is normally present at. hemoglobinopathies (hemoglobin disorders) hemoglobin is produced by genes that control the expression of the hemoglobin protein. defects in these genes can produce… Hemoglobinopathies are frequently linked to artifactually altered hemoglobin a1c (hba1c) concentrations.5 in blacks with prediabetes, the presence of the hemoglobin s variant is associated with a higher hba1c concentration and this eleva-tion is not an artifact.6 blacks compared to non-hispanic. The hemoglobin a1c blood test (or simply the a1c test) is an essential tool in diabetes care because it shows a patient’s average level of blood glucose control in the previous 2 to 3 months. physicians base their treatment decisions in large part on the a1c test results..
