I use QUEST diagnostics and they provide great service and customer support.
They are a leading provider of diagnostic testing, information and services that patients and doctors need to make better healthcare decisions.

They perform medical tests that aid in the diagnosis or detection of diseases, measure the progress or recovery from a disease or confirm that an individual is free from disease. We have specialized expertise in cancer, cardiovascular diseases, infectious diseases, and neurology.
Hemoglobin A1C test. This test measures how much sugar is stuck to your red blood cells, which generally have a lifespan of three months. Therefore, this test gauges how high your blood sugar has been in recent months.
Normal result for nondiabetics:
4% to 6%.
Normal result for diabetics:
7% or lower (some groups suggest aiming for 6.5% or lower)
If a hemoglobin A1C test result is 8% or higher, it’s a sign that blood sugar is not under control. However, making lifestyle changes can reduce your A1C.
