Help please on fasting sugars

[Grazer]

I'd be grateful if anyone could help with the following.
I noticed a couple of posts where people spoke of doing they're fasting sugars "first thing on getting up", on the basis that sugar levels rise as you start getting dressed etc. So I thought I'd check this.
Normally, I get up, shave, shower etc, get dressed, go downstairs and then test if I'm doing a fasting test.
So twice recently I tested as soon as I got out of bed and then again later in the normal way downstairs. Each time, my bs had gone up by 0.5 on the later test, from 6.0 to 6.5, and from 6.4 to 6.9 the second time. So two questions if I may:-
1) Is this about the same for everyone? (The amount of change)
2) If so, how does this stack up if we have a fasting blood test at the doctors or the clinic? Do they allow for the fact that it would have been lower earlier? Is this allowed for in their guidelines of what fasting sugars should be for non-diabetics/well-controlled diabetics?

Your views would be appreciated

Morning fasting tests can be affected by the well-known 'liver glucose dump' that people experience as the body prepares for action. This can vary greatly between people, so I'm not sure how reliable overnight fasting tests really are unless this factor is taken into account. I tend to rely more on measuring my sugar 2 hours after a reasonable meal toegther with the GPs HBA1c measure which tests the average BS level over 10 weeks or so. Interestingly the advice given to me for the minimum/maximum hours before the last meal and the fasting blood sample has varied between different phlebotomists who have taken my blood which indicates no one is quite sure when to sample in the morning?

Thanks daibell, think you're right - fasting tests as such aren't much help.
