Unsure

'Normal' in what way? A rise of 2.9 after eating would be within the expected zones of normality, after a sandwich, that probably included a couple of slices of bread and whatever filling. I think most of us would be pretty happy with those numbers after that meal. But we might be able to give you a better answer if you elaborate a bit on your question.

Do you mean what would be a 'normal' reading for a non-diabetic person? There's clearly a bit more to diagnosing diabetes than a couple of random home tests (there's a margin of error in home meters, they're not as accurate as venous blood tests), so you'd really need to discuss this with your medics - especially if you've just had a big infection, it can play havoc with blood chemistry, including blood glucose. If those tests were taken around the time of your infection, it might be very different now.

These are the NICE recommended target blood glucose levels:

Non-diabetic - Before Meals: 4.0 to 5.9 mmol/L 2 Hours after meals: under 7.8 mmol/L
Type 2 diabetes - Before Meals: 4 to 7 mmol/L 2 Hours after meals: under 8.5 mmol/L
Type 1 diabetes - Before Meals: 4 to 7 mmol/L 2 Hours after meals: under 9 mmol/L

Hi everyone has a different level at which they like there BS to sit, for myself I like to be in the low 5s fasting and two hours after a meal but others are happy in the 6s or 7s. To avoid complications it is best to try and aim for non diabetic numbers as those readings are slightly high for a borderline pre diabetic. It would be well worth making an appointment with your GP to get your HbA1c test redone once you are completely well and if you have the means keep testing your BS as it might give you a better picture of any spikes or lows you may be experiencing. Please keep us informed and if you have any further questions don't be afraid to ask.
