Is it a blood test?

Also what type is more common 1 or 2?

And lastly i heard people who have diabetes can not have children because it is very risky.

I’m 19, I’m worried I may have diabetes and I don’t have health coverage/insurance so I can’t go see a doctor. Is there a cheap way to check if you have it without having to go see a doctor?
Thanks for the tips guys but I don’t know anyone close to me who has diabetes, none of my friends got it. I don’t think anyone in my family has it so I can’t go to them for help. I’m not overweight either.

I had a fasting glucose test in late 2006 which returned normal. I went back to the doctor this week and he recommended I retest every 1.5 years to monitor that until I bring certain risk factors under control. Is it possible to go from normal to full blown diabetes in a year?
