Hello and welcome to the forum. We usually leave the medical proffesionals to diagnosis. Although it is most common to go by HBA1C these days, 5 years ago two fasting tests over 7 would have been enough to diagnose diabetes in the UK.
I was diagnosed with impaired fasting glucose initially with a 6.3. My doctor said I was borderline otherwise known as prediabetes.
I will tag
@daisy1 for her new member post which I found so useful when I joined the forum.
