How accurate are glucometer readings really?

I've started wondering how much small things can mess with a glucometer reading.

For example, I've definitely tested without washing my hands first, and I also have a box of strips that has been sitting in a cupboard for quite a while. With the weather getting hot and humid, I'm wondering if storage matters more than I realised.

Can expired strips, humidity, heat or having something on your fingers actually give you a noticeably wrong result?

What do you normally do when you get a reading that just doesn't make sense? Do you wash your hands and test again, use a new strip, or just assume meters sometimes vary?

Unwashed hands absolutely caught me once. I had been cutting fruit, checked my sugar and got a number that made no sense. Washed and dried my hands properly, tested again and it was completely different.

Same thing happened to me after eating mango 😂 That was the day I stopped being lazy about washing my hands before testing.

Fruit seems to be the perfect way to scare yourself with a finger stick.

Drying your hands matters too. I used to wash and immediately test with my finger still slightly wet. Now I wash with soap and water, dry properly and then test.

This is one of those tiny things nobody thinks about until they get a weird reading.

I wouldn't rely on expired strips, especially if you're using the result to make a treatment decision. The strips have an expiry date for a reason. I'd rather open an in-date pack than spend the next hour wondering whether the number is real.

I found an old container in my travel bag once and almost used it because I didn't want to waste them. Then I realised saving a few strips wasn't worth questioning every result.

Exactly. Especially when you already have a reading that's unexpectedly high or low.

Humidity is why I stopped keeping loose strips anywhere outside their original container. I take one out and close it again immediately instead of leaving the lid open while I do everything else.

My mother leaves the strip container open on the table constantly and this drives me crazy.

Mine used to do the same. I finally told her to treat the lid like the refrigerator door 😂 take what you need and close it.

Heat is something I'd check against the storage instructions for your exact strips. I wouldn't keep them in a parked car or somewhere that gets extremely hot. The meter and strips both have storage ranges in their instructions.

The car one is easy to forget. I used to leave my whole testing kit in the glove box so I'd always have it with me.

Same, until I got into the car one afternoon and realised how insanely hot everything in there was.

If I get a number that seems completely wrong, I don't immediately panic. I wash and dry my hands, use a fresh strip and repeat it. If the repeat is still concerning, then I take it seriously instead of endlessly retesting until I get a number I like.

That last part is important. There's a difference between confirming a suspicious result and testing five times hoping one of them says you're fine.

That's a good way to put it. I think I sometimes treat the second test like I'm trying to prove the first one wrong.

Also don't expect two finger sticks to always give the exact same number. Home meters aren't laboratory machines. I look for whether the reading makes sense in context rather than expecting identical results every time.

@rashmi08

This used to bother me so much. I'd test twice and get two different numbers and immediately assume the meter was broken.

@avinashpatel

Same. I think seeing a number on a screen makes us expect way more precision than these little home devices are designed to give.

I keep one unopened backup pack of strips now. It saved me once when the open container had been stored badly and I started getting readings I didn't trust.

@avinash91

That's actually a good idea as long as the backup doesn't sit there long enough to expire too 😂

Don't expose my previous system like that.
