Should i be checked for diabetes? fasting checked was 70 then ate lunch then checked it 1.5hr later 107 then 4.5hr 98 then 2hr it was 80

Already checked: While you did not have an oral glucose tolerance test done in a lab, the fasting and post-lunch testing you did should convince you that you do not have diabetes or prediabetes. If you did your fasting BG would be >100 and after eating it would have risen to at least 140. If you are overweight you should try to lose weight but as of now definitely no diabetes.

No: None of your values cross into the territory of what is considered to be diabetes or even prediabetes. Generally, type 2 diabetes is checked in patients younger than 45 years old if they have risk factors for it (eg., family history, overweight, hypertension, etc). However, you have done that check now by looking at your glucose levels. Keep your primary care physician informed of your history.
