Confused with results

[MrsB80]

Hi, I had a blood test that showed my mmol at 7.3. This was a morning test and I'd only had a small glug of coke before it so they wanted to test again with a complete fast. The fast test came out at 6.8. I was booked for the oral glucose test but as it was two weeks away I decided to get a monitor and try to understand which foods were increasing the mmol. Over the two weeks I was non the wiser re food but every morning my first fast result was between 6.2 and 7.7. I would also test 2 hours after lunch and this was anywhere between 7.7 and 9.8. So yesterday I went for the oral test. I tested using my monitor right before the first and second blood test as I wanted to see how accurate my monitor was. My monitor measured 6.8 then 9.2 however the nurse called me this morning to say my results came back (unusually very quickly for my surgery) at 5.9 and then 6.0 for the second test. I realise that my own monitor wouldn't be completely accurate but this is a huge difference particularly the second test. Are these differences plausible and would you expect my second test to only have risen by 1mmol after 75g of glucose? I'm still waiting for the Hba1c result. My monitor is a SD Codefree. Thanks for listening (reading), any advice would be helpful as I'm not sure if I should be concerned or not.

Hi and welcome,

Your fasting test of 6.8 is in the pre-diabetic range. However, these tests are extremely unreliable for a variety of reasons, which is why they are no longer used for diagnosis and why you had the OGGT and HbA1c. I imagine you were pretty stressed or anxious at the time, and no doubt rushed about getting to the surgery etc. All this will have affected that reading.

Your own fasting tests are also subject to matters outside your control, such as liver dumps (dawn phenomenon - plenty about this on the forums if you do a search). Your own post lunch ones don't really mean anything without a before eating test, and will have depended on exactly what you ate and drank. The higher you start the higher you will finish, and the more carbs and sugar the higher it will be..

Normal blood sugar readings

I have to agree the second test after 75g of glucose that showed 6 is a bit odd but very good if it was correct.

These are the normal standards:

Type 2 diabetes
If you're being tested for type 2 diabetes, two hours after drinking the glucose solution:

• A normal blood glucose level is lower than 7.8mmol/L
• A blood glucose level between 7.8 and 11 mmol/L is considered impaired glucose tolerance, or prediabetes. If you have prediabetes, you're at risk of eventually developing type 2 diabetes. You're also at risk of developing heart disease, even if you don't develop diabetes.
• A blood glucose level of 11.1 mmol/L or higher may indicate diabetes.

No two meters will ever give the same result, no matter how close together the tests are. Even from the same drop of blood. In fact it is highly unusual to get 2 identical readings from the same meter. All meters are required to conform to the same accuracy standards, and there is no reason to believe your nurse's meter is any more accurate than yours. (although I imagine the surgery meters are calibrated frequently)

All you can do is wait for the HbA1c result, and then come back and let us know what it is. Good luck.

you could maybe have traces of something sweet on your fingers ?

or you have the dawn phenomenon that most people have; where their morning blood glucose is raised in the morning also when not eating anything at all.
it is the liver sending out some of the reserves or/and transforming protiens into glucose by it´s own, the same thing happens when one is suddenly very stressed , then the body makes the glycose by it self either from reserves or proteins stored in the liver or taking it from ones muscle-proteins...
this is why we have to eat the needed amount of proteins on a daily basis , which is around 1 grams of proteins pro kg body weigth, and if body building 1.5 to 2 grams pro kg body weight (for men at least ) many women only need around 0.8 gram pro kg body weight.

the most spiking foods are ;

white bread baguettes, watermelon, fruit-sugar and sugar.Grains and rice and potatoes , lemonade, sweets, chocolate except from 90% dark chokolate, corn flakes, cakes, so all these should be avoided..

seems you are close to the prediabetic area. the green area is the non diabetic area...
