Is this the definitive conclusive test that one doesn't have diabetes?

I bought a b.s. monitor because i want to check my self and see if my numbers were fine. cause i figured they would be.

after i eat a small bowl of cereal it went up to 198 and i felt like a was outta my mind, and i was so damn thirsty, but within an hour it had dropped down to about 150 and lower from there.

if my blood sugar is spiking rapidly and than looks normal at the two hour mark, does that guarantee i don't have diabetes?

should I request a 1 hour glucose test, so they can see how far up my bs spikes after a 50mg sugar drink?


during the 2 hour test they only test at 2 hours, not during it, which i find ridiculous. but again im not a doctor or scientist.

if only pose this question, because i keep getting so thirsty and dehydrated and sick after eating. obviously could be something else.

seein' the doc tomorrow, gonna see if i can get a 1 hour test done.
