Syringes being off

[Mimis mom]

The first two are Relion, BD, the last two are Ulticare.
Now, if you zoom into the last two- one has the solution right to the line and the other has some creeping into the needle head.
The one that has the solution showing in the head was one I used already, so it prompted me to check another one.

why did this happen? I like the Ulticare because they don’t pull bubbles and the plunger glides smoothly around every measurement line- Relion would get stuck around the 1.5 mark and if I was trying to get the right dose it wouldn’t allow me to use light pressure to get it to move.

No idea, sorry. In Canada we have a choice of BD or BD. So that’s all I know.

why does one pull some liquid into the “hub”

Maybe it was just a bad syringe. Unfortunately there is not good quality control with syringes. Sorry I don't have a better answer. We just have to hope the doses are close to being consistent with syringes.

I wonder if it’s been effecting her BG- some cycles she’s getting more than others.

Just stumbled across this thread and wondered; why is the insulin green? Please pardon my ignorance if it's a dumb question!

Colored water lol!

It may be, but it may not since it's just a tiny bit.

Considering these syringes are also meant for humans this is pretty shabby. Why are we even using calipers? Just find this annoying in general that this passes FDA requirements.

Because calipers work quite well ....extremely well.

FDA requirements are not set for syringes to be used with pets. The dosage difference for a cat can be significant but not for a human; likely not even for a 40 or more lb child.

Some syringes, like Monoject, have a hub in them above where the insulin normally goes. If a manufacturing defect causes the needle of the syringe to end above the barrel and into the hub, you will get insulin into the hub. It’s the reason I quit using Monojects. I have never used or looked at Ulticare but I suspect there might be a similar reason. If you use a syringe that does not have the hub, then you can use calipers very reliably.

That part I get. What I find unacceptable is that the medical establishment accepts these deficiencies in what should be considered a medical device and that it's not just animal grade makes it worse. I'd gladly pay a nickel more if that's what it took.
I accept that a hand held unit that measures any form of blood chemistry is almost a miracle in itself. I dated a diabetic girl in the 70's and we had to sneak Tab into theatres so we've made a lot of progress but even lawnmowers have tighter manufacturing tolerances than syringes. I know I'm stating the obvious but we can and should expect better.

The last two or three boxes of syringes I bought have been Monojects - and in this last box I've noticed maybe 1 in 5 is a bit off. Frustrating, as I thought that brand was supposed to be one of the better ones. Up to this point I've been one of the folks who thought calipers weren't for me -- I'm thinking I'll pick some up soon.

When we started out, we used MJs and I loved them. But then Gracie’s BG started getting wacky and I started noticing that insulin was going into the hub.

That’s when I started measuring and then developed the caliper method. I went to battle with the makers and for nowhere. They didn’t care and that was with me not telling them I was using them for a kitty.

I have heard there has been improvement with the MJs. I’m glad!

@Marje and Gracie I imagine arguing with any big corporation now is just pointless but I'm glad you made the effort. Did you find out what the FDA and Canadian minimum standards were? That should be public knowledge as should the EU standards. And yes I've been the target of a lot of snickering from pharmacists that this was all for "just a cat". I actually pulled myself together long enough one day to embarrass a pharmacist over the effort I made with Nigel who was a real low maintenance patient.
Consumers have no power anymore, maybe veterinary colleges would have better luck having minimum standards imposed.
This is all so wrong, I have $30,000 worth of platinum coil in the back of my head that probably has a recycle value of $100. I get that biomedical research etc. is expensive, all we want are plastic and metal tubes made using established and well known methods. My rant for today.
