Thanks everyone for some great posts.
I didn’t realise Gary Scheiner has a book specifically for CGM use. I actually recently obtaineda copy of his Think like a Pancrease book, which I’ve found informative. Admittedly it is a lot of reinforcing stuff I already knew/do but he raises some new concepts I’d never heard of before.
@Terry4 There is only on distributer for Dexcom in Australia, when you order it you can get extra transmitters with it but as standard it comes with 1 Transmitter, 1 Receiver, and 4 sensors. At the moment they actually give you 4 sensors for the price of one. I didn’t want to invest in a second transmitter until I had tried it out for a bit. The G5 transmitter in Australia is only $40 cheaper than the G4 transmitter, the G4 i beleive is $580 per transmitter, with the G5 being $540 so unfortunately we don’t seem to have the same luxury of half price transmitters.
I’m aware of the 15 minute lag, in fact it was a point that my endocrinologist used last year to turn me off using CGM. My understanding though is that you calibrate the meter so that even though it technically lags by 15 minutes, it reflects what your blood glucose reading shows in your standard glucometer. Is that correct? If not, how do people constantly find they have fairly similar readings with their standard glucometer?
One point I’m really unclear on is the ‘accuracy’ of the G5. When I met with the Dexcom rep for my region she told me that the G5 has a 9% area of difference to your plasma blood glucose readings. This would to me indicate that it’s potentially more accurate than your standard glucometer, which have a 15-20 % discrepancy.
