How to make your Freestyle Libre fix your diabetes .

[madusmacus]

Ok my 3rd sensor always reads 1-2 MMOL to high so I just had a play around

My sensor was saying 8.7 MMOL after a cup of coffee/cream this morning so I didn't believe it
tested my Blood glucose a lot of times to get an average and I was really 6.2 MMOL (2 meters 3 stick average)

SO... I decided to cup my hand over the sensor for 30 seconds and retest
Voila! 8.4 MMOL - did it again 7.8 MMOL then 7.2 MMOL so...

If you don't like your readings fix it by warming up your arm /sensor

There you go you my diabetes is now is now fixed and you I don't have to worry every again <Jokish>
Marvellous device.

Serious though I think its something to do with moving the sensor or warming the fluid up - I dunno
If anyone else can try this out would be good to know for me and abbot :¬)

When you say cup your hand, were you applying pressure? Normally heating the sensor causes an increased reading and pressure on/around it decreases it.

maybe I did apply pressure thanks for the info - I will recheck

might explain night time wackiness
sensor 2 was always very low overnight and it was on my arm I lie on when sleeping (involuntarily)
also might explain why sensor 2 all ways jumped up a lot on waking up (reliving the pressure on it)

hmmm even more mind boggling things to think about :¬)

tim2000s yep its pressure not heat
I can lower the reading 1 MMOL just but light pressure on it for 30-45 secs :¬)
arm near cuppa hot coffee didn't realy do anything

So im guessing depends where the insert lies in the tissue makes the sensor susceptible to variations
2nd sensor always was low so maybe it was in tissue that applied pressure and this sensor 3 is always reading high because its in tissue that exerts less pressure

This system needs some user calibration feature as all these lovely graphs are pointless when they show un normalised values from different sensors

guess I could dump out the data make my own spread sheet with some normalizer feature
might do that for a laugh :¬)
