Will earlier blood tests distort later blood tests if there isn't much of a gap

Hi
If I have a blood test on Monday for lipid profile and hbA1C etc and then another blood test a week later will the later blood test be disorted by the earlier one? I understood that if you lost x amount of blood you're body will replace it so if HbA1C looks for blood sugar levels for the past 3 months the blood take for testing will be replaced by 'new blood' won't this distort any further tests?

Thanks
 
As a proportion of your body's blood volume, any impact would be utterly miniscule, in my opinion.
 
I don't know the scientific answer, but they only take a very small amount of blood for testing, which I believe will be replaced in your body fairly quickly.
 
If you are a blood donor, then this can affect your HbA1c, but a small sample for a test won't.
 

From 13 minutes especially!
