Hemoglobin A1c (HbA1c) with calculated glycated albumin ratio
This test measures your average blood sugar levels over the past 2–3 months by analyzing hemoglobin A1c and glycated albumin, which reflects how well your blood sugar has been controlled.

Why This Test Matters for Blood Sugar Management
HbA1c alone provides a snapshot of your blood sugar trends over time, but combining it with glycated albumin gives a more comprehensive picture of how consistently your blood sugar has been managed. This test is particularly useful for people with diabetes or prediabetes who want to track both hemoglobin and albumin glycation levels together.
How the Test Works: Analyzing Glycation Markers
The test measures hemoglobin A1c, which attaches to red blood cells and reflects average blood sugar levels over months. It also calculates a ratio involving glycated albumin, a protein in blood that reflects more recent glycation trends (typically the past 2–3 weeks). Together, these markers help identify patterns in blood sugar control that a single HbA1c might miss.
What This Test Can Tell You About Your Health
This test helps identify whether your blood sugar levels have been consistently high or low, which can indicate how well your diabetes management plan is working. It may also reveal subtle shifts in glycation that could signal underlying metabolic changes, such as changes in kidney function or protein metabolism.
Common Reasons for This Test
Your healthcare provider may order this test if you have diabetes and want a more detailed view of your blood sugar control, if you have kidney disease (which can affect albumin levels), or if you’re evaluating how well medications or lifestyle changes are working over time.
