so, what reading am I supposed to believe here...

So, not sure what is going on here. I am about 6 weeks diagnosed as T2, and there are still so many things I am learning. But this one has me stumped. Why am I getting such a wide range of readings? I am really confused.

From left to right

Blood test, blood test, libre sensor scan...

Why is there such a big discrepancy in the readings?
