So today was my first time testing my blood sugar. I have a ReliOn All-In-One and when I finally managed to get a little blood on the strip I got a E-2 message meaning there wasn't enough blood on the strip. So I tried again with more blood and same. I tried a different tactic to make me pretty much pour blood and put a lot on the strip covering the tip. I got the E-2 message. There was no way there wasn't enough blood. I am confused cause when my mom does it she doesn't get an error. This is my mom's older glucometer that she only had for a few months before getting a better one. It wasn't like this one was bad she just wanted a more portable one understandably. Any idea what is going on? I pretty much just wasted 3 hours trying this and I'm just glad that I'm only prediabetic so it's not like I need this or I die.
