I'm confused by morning tests.

I decided recently to do a little more testing for fasting blood sugar.

My normal routine is to test at 9 AM having not eaten after 6 PM the night before. I am happy that most days I get a reading of around 100 (5.5).

Last few days I tested when I woke up around 6 AM, some 3 hours before my regular tests.

This is what I get

6 AM 9 AM
92 (5.1) 104 (5.7)
86 (4.7) 97 (5.4)

After the 6 AM reading i take my meds for blood pressure and an aspirin. I drink a small pot of English Breakfast tea (no milk no sugar) and walk 2 miles. I was under the impression walking should lower, not raise blood sugar.

I am not worried, I am happy with my readings but curious now. Which reading would be my true fasting reading, 6 or 9 AM?

Any suggestions.

Poor grammar, bullying and drunks.
A more reliable fasting test should be taken on waking, so before you jump up and start your day.
My routine is wake, wee, wash (hands) and test.

Around the time we wake we have what is known as Dawn Phenomena (I'm sure you know this), this is when the liver splurges glucose to give us the energy to herd that mammoth off that cliff or to get the kids off to school on time!
