Markers tested for at home A1c test: HbA1c
What is HbA1c?
HbA1c (or hemoglobin A1c or glycohemoglobin) is a minor component of hemoglobin to which glucose is bound. Hemoglobin is an iron containing protein in red blood cells that gives the red color to blood. Hemoglobin is responsible for carrying oxygen throughout the body.
Why measure A1c?
Since glucose binds to HbA1c, higher levels indicate higher glucose levels. As the red blood cells have a life span of about 90 days, the HbA1c test is a good indicator of average glucose levels over a period of 3 months. HbA1c is not influenced by the daily variations of glucose but gives average value over a long period. It can not replace the daily glucose monitoring for those with diabetes. However, it is a useful test to measure levels over longer period for those with diabetes or pre-diabetes.
What are the signs of high A1c levels?
Those with possible signs of diabetes see unusual thirst and urinating, fatigue, and itching. Sugar craving is also frequently observed and it takes longer for wounds to heal. Heredity plays a big role in diabetes and those with a family history of diabetes should test their A1c levels regularly.
How to check A1c levels?
The easiest low-cost way to get tested for A1c is from the convenience of your home. Simply order an HbA1c test kit, collect a few drops of blood on a tissue paper, send your sample to our CLIA-certified labs to find out your levels within a week.
For a short description for A1c ranges, you can read the Medline.gov page on HbA1c test. For understanding the difference between A1c and eAG, the average glucose levels, please see the American Diabetes Association’s page on A1c. You can also order a separate test to understand your cardiovascular risk from higher HbA1c using at-home Cholesterol and Heart Health test.
