Should I change my pcp?

I had a doctor's appointment recently for blood work. They drew blood and said they were going to do an A1c so I asked the nurse if she can tell the doctor I'm requesting to also have a fasting blood glucose and a oral glucose tolerance test done for a more thorough and accurate testing and results but I was told they only do A1c so when I asked if I can get a referral to see a doctor that does use the fasting blood glucose and ogtt he just brushed it off by saying A1c is just as good. Should I seek a different PCP if I ask again and he still refuses?

Should I change my pcp?
