Ooher just realized that my RBC count was low on my last test so my HbA1c test would have been unreliable had not occurred to me to check till @Bluetit1802 mentioned RBC and haematocrit levels.
I must admit HbA1c of 35 was somewhat lower than I had anticipated compared to averages but just reviewing my results I found that my haematocrit level was actually dead on the lower reference level at 4.00 though my RBC count was quite a bit lower than the lower reference level so would be counted as anemic, thus skewing my HbA1c I would think.
Thank you all for the responses, being an IT guy (always getting in the way, like all day today, but can't complain really) I am only just getting back to this thread. So thank you ladies and gents; I don't know about others but as a techy type I have a built in must know nature.How often are you testing as unless you are testing every day upon waking, before meals and 2 hours afterwards every day your meter's average may not be correct. There is also the margin of error that is present in meters and sometimes different fingers or different batches of test strips can vary readings as well.
Hi,
I have exactly the same problem as yourself @Mbaker
The problem doesn't lie with white blood cells at all, it lies with red blood cells as that is where the glucose is carried (haemoglobin). The HbA1c measurement is based on the average life span of red blood cells, which is approximately 120 days. As we are all aware, not everyone is average. If our RBC live longer than 120 days our HbA1c will be higher than other tests indicate. If they live less than 120 days the HbA1c will be lower than other tests indicate. If there are abnormalities in our RBC the HbA1c can be skewed. There are other factors that affect it.
I no longer take any notice of my HbA1c other than watching for trends. I rely on my finger pricking and an occasional Libre sensor for a more realistic measurement of my blood glucose levels.

My haematocrit levels are always right at the top of "normal", teetering on being elevated and about to fall over the line. As this is one thing that can affect HbA1c levels, I believe in my case this is the reason.
That's interesting, does the Freestyle Neo typically under read? As a T1, I'd be having to treat for a hypo at that reading and unnecessary glucose is really bad for my control....Just got to my Hotel. Blood sugars 3.9 mmol on One Touch Select Plus, 4.1 mmol on Accu Chek Mobile, 62 (3.4 mmol) Freestyle Neo.
For me it us always less than the Accu-Accu-Chek and One Touch. It appears whatever algorithm Freestyle products use don't work for me.That's interesting, does the Freestyle Neo typically under read?
