What is an A1C test used for and what do the different results indicate?

"An A1C level is used to determine if a patient has diabetes. A result of 6.5 percent or higher on two separate occasions indicates diabetes. A result between 5.7 and 6.4 percent is considered prediabetes, which indicates a high risk of developing diabetes. For most people who have previously diagnosed diabetes, an A1C level of 7 percent or less is a common treatment target."

The A1C test is a common blood test used to diagnose type 1 and type 2 diabetes and then to gauge how well a patient is managing diabetes. Taking the time to know what a test is for, rather than simply drawing blood and sending it over to the lab, shows the interviewer that you have a true interest in your job as a clinical lab tech.
