I also have the multi-clix, I test around 10 times a day on average, changing my lancet when I remember, my husband is also the same with his lancets..
As to this causing any problems, well never got an infection from it nor have I got sore fingers, if you looked at my fingers you really wouldn’t be able to tell that I constantly stabbing them!
It is personal choice whether you follow the manufactures instruction of use one then dispose of, as this is partly them covering their own backs... Helps to prevent Muppets from sharing used lancets
I have yet to get an infection from my lancet, nor has my hubby and I haven’t yet come across a diabetic that actually has, so the changes of causing a infection in the finger because you’ve used more than once is a very pretty long shot...
But there again, the lancet only pricks the skin to retrieve blood, how many times a day can we prick out fingers on other objects which are exposed to contaminates? The lancet is covered when in situ, it’s kept with the meter within the meter bag, so very difficult to get a wondering contaminate onto it... You are only using it on yourself and nobody else so no other person’s human body fluids to cross contaminate the lancet.
You are probably more in danger of pushing an contaminate that’s already sitting on the skin which shouldn’t be there because you haven’t washed your hands with a fresh lancet than you are causing yourself problems with one that you already used!
Ask yourself one question a good one to ponder, if the risk of infection is so high then why do lancets come lose in a box of 100-200 rattling around, or shoved in the side of the meter bag where the seals/plastic protector can get damaged quite easily!
