Thank you for your response, the docs have done blood tests a few times over the years as this condition is not new to me it’s been going on for years but probably due to age is happening a lot more frequently. The test strips are all in date. The low readings can come at anytime, that reading of 2.7 I had woke feeling like I’d been on the booze all night and had the shakes in my hands for well over an hour so as an after thought I checked my bloods and realised it was super low, after I ate chocolates, biscuits and couple rounds of bread it rose to 4.7 and I was feeling lots better and the shaking went. It’s also happened when I’ve been out shopping, I go pale, start feeling woozy and stat shaking at which point I head straight to the chocolate isle lol I’ve also had it occur when I’ve just woke up and during the night. I suffer hypothyroidism maybe it’s that which is causing my bloods to be irrational at times.
