Hi All,

This morning I tested before breakfast, my reading was 7.1. This surprised me as my BG level before bedtime was 7.3 (taking insulin in morning only, not in the evenings..at the moment!). anyway, I tested again (same finger) and my BG level reading was 6.6, so i tested the same spot again and it was 6.1. Which is the correct reading? Please explain the variations as I don't get it?!!

I'm using caresensN Bg monitor and strips

PS: Did 45 mins of cardio workout at the gym last night after evening meal.

Thanks
 
HI
Your saying 7 is high for you, i would love mine to be that low all the time. Out of the three test you did i would take an even kill and go by 6.5. You will be fine, what did you have for your evening meal or did you have any snack after your exercise class as this may have upped your sugar levels, but honestly don't over worry we all have occassions of ups and downs.
I am on Novarapid three times a day and Lantus solar star at night and 2 x 500mg of Metformin twice daily.
I have had diabetes for 36yrs and i am now 42 now, but i have several complications, may be i should of taken a little more care of myself.
Hope all goes well.
Take care, keep in touch if you wish.

Arty... I find its not unusual to get a range of BG readings from a single test point although 1 mmol difference is a bit more than I would expect. I find on my metre that if I only just get enough blood it will give a reading but this can be artificially high... Either way the metre's are not 100% accurate as they are an estimation only in the case above I would use an average... if for instance the reading were varying in and out of hypo range I would trust the feel of my body and act accordingly and then re-test 15 mins later.
 
Hi. I would suggest you avoid morning meter testing and test 2 hours after a typical meal during the day. The liver often does a glucose dump overnight to start the day with some energy and this can cause variable early morning readings that don't really indicate how well your diabetes is being managed
 
Hi, new to the forum.
I've just tested 4 hours after eating and had a reading of 13,8 which was a surprise. I immendiately retested (twice) and had readings of 4,8 & 4,7. How reliable are these meters?

They can be +/- 10-20% out depending on the meter make, did you wash your hands after the first reading of 13.8?

Yeah, always wash before.....wondering if it was a dodgy strip.

Could be although I doubt this is the case. Check the accuracy of your meter using the control solutions that came with your meter........it might just be you have a faulty meter.
