Glycated Albumin Blood Test
Test Code: 123030
Specimen Type: Blood
Glycated Albumin Blood Test (Labcorp)
This test measures the percentage of glycated albumin in a blood sample. Albumin is the most common protein found in the blood. When there is excess sugar (glucose) in the blood, albumin can become glycated or bound to sugar. The body replaces albumin about every 20-25 days. Because of this, measuring the level of glycated albumin can show how well a person has been managing their glucose levels over the past 2-3 weeks. This information can be useful for people who are diabetic or at risk for diabetes when used in conjunction with hemoglobin A1C testing. A1C testing provides a measure of average blood sugar over the past few months whereas glycated albumin looks at a more recent window.
Measuring glycated albumin levels can also be useful for people with conditions that can affect the accuracy of an A1C blood test. For people with conditions such as iron deficiency anemia, hemolytic anemia, sickle cell disease, and other inherited hemoglobinopathies a Hemoglobin A1C test may not provide an accurate measurement of their average blood sugar levels. In these cases, glycated albumin can be a more reliable testing method. Since A1C can rise naturally during pregnancy, glycated albumin can also be a more accurate way to screen pregnant women for gestational diabetes.
This test can be ordered when someone is monitoring their risk for diabetes or has already been diagnosed with diabetes and needs to monitor their glycemic control. Glycated albumin can be ordered along with a Hemoglobin A1C test for a more comprehensive look at blood glucose levels. Results for the glycated albumin test include the normal reference range as well as the range for prediabetes and diabetes.
Turnaround for this test is typically 2-5 business days.
