Our HbA1c test is a blood spot sample test that will show your average blood glucose levels (blood sugar) over the last 3 months. Red blood cells have a lifespan of about 3 months, but are constantly forming within the body. Glucose attaches itself to hemoglobin, which is the protein found in red blood cells that carry oxygen throughout the body. The HbA1c test measures this glucose to give you an overall look at your blood sugar levels over a 3 month period. Quickly and easily collect your own sample from home on your own time using our easy-to-follow instructions and collection materials. All results are independently validated by a physician in your state to ensure validity and reliability. No doctor or lab visit required.
