a day's worth of testing

My diabetes educator asked me to take multiple blood samples today. I did and the results were interesting. Number 4 and 5 were shocking...

1.  522 am - 122
2.  943 am - 112
3. 1156 am - 136
4.  229 pm -  251
5.  456 pm - 198
6.  743 pm - 129

Test 1 was after I got out of bed (5 am) dressed and walked my dog. Test 2 was after breakfast. Tests 3 and 4 bracked lunch and tests 5 and 6 bracked dinner. I wonder if test 4 is representative of what my blood score is at that time of the day. I will have to do another multi-test day next week when I have a day off (Friday, Saturday or Sunday).
