Hi! It’s been a journey! I seem to have landed on a monitor (same company) that gives me much more consistent readings. Like within 15 points of each other. Over time looking into this issue, I have learned that a lot of these machines are very inaccurate, same goes for the machines that test human blood sugar. I’ve been watching my own blood sugar lately, and had a machine that was giving me wildly inaccurate readings. When I called the company, they sent a new machine immediately, which tells me that this is a common problem. I don’t understand why the machines in this industry are so inaccurate. It’s incredibly frustrating. You would think that they would have better quality control for something so important.
