Carter's little fingertips look like a black warzone, and that's using the Multiclix 10 times/day. Does anyone use the Aviva and alternate site testing? Friends use the Freestyle and test on the calf and have no problem, but when I use it with the Aviva I'm always suspicious. Once it was 100 points off from the fingertip - although the Aviva says it's approved for alternate site testing. Does anyone use the forearm, palm or leg with the Aviva (with reliable results)? I've just got to give his fingertips a break. Any ideas would be appreciated.
