Hemoglobin in red blood cells gives blood its red color and carries oxygen from your lungs to all parts of your body. some forms of hemoglobin can cause false results for a diabetes blood test called the a1c test.. Results. most people have only one type of hemoglobin, called hemoglobin a. if you have an uncommon form of hemoglobin (known as a hemoglobin variant), your a1c test result may be falsely high or falsely low. hemoglobin variants are most often found in people of african, mediterranean or southeast asian heritage.. Learn in-depth information on hemoglobin variants blood tests, on why the laboratory test is performed, specimen collected, the significance of the results, and its use in diagnosing medical conditions..
Hemoglobin abnormalities and a1c testing. my first thought was a faulty meter and so immediately we gave her another one but upon first use in the office the glucose readings on each were 122 mg/dl and 128 mg/dl respectively. i had her use the new meter for 7 days and return. the readings on the meter indicated that her a1c should be in the 7.6 range….. The a1c test evaluates the average amount of glucose in the blood over the last 2 to 3 months by measuring the percentage of glycated (glycosylated) hemoglobin. hemoglobin is an oxygen-transporting protein found inside red blood cells (rbcs). there are several types of normal hemoglobin, but the predominant form – about 95-98% – is. Purpose of test. the a1c test measures how much glucose is actually stuck to hemoglobin a, or more specifically, what percent of hemoglobin proteins are glycated. hemoglobin with glucose attached to it is called a1c. thus, having a 7 percent a1c means that 7 percent of your hemoglobin proteins are glycated..
Co-elution of the hemoglobin variant with hba1c will cause gross overestimation of hba1c, while co-elution of the hemoglobin variant with hb a, with resolution of the glycated hemoglobin variant from hba1c, will underestimate the hba1c results.. Hemoglobin variants and the a1c test. the hemoglobin a1c test, glycated hemoglobin test, or glycohemoglobin, is an important blood test that shows how well your diabetes is being controlled.. information for physicians and patients regarding common hemoglobin variants that assay interferences. hba1c, also called a1c, a1c tests give falsely.. Factors that interfere with hba1c measurement: genetic variants (e.g. hbs trait, hbc trait), elevated fetal hemoglobin (hbf) and chemically modified derivatives of hemoglobin (e.g. carbamylated hb in patients with renal failure) can affect the accuracy of hba1c measurements. the effects vary depending on the specific hb variant or derivative and the specific hba1c method..
