| I agree with the previous comments... I have never used alcohol and have never had an infection. Of course, you do have to be clean and I always wash my hands before testing or handling injection materials.
The reason you sometimes see a bit of blood after injecting is that you must have hit an capillary when you inject. Capillaries are the tiniest of blood vessels that are close to the surface of the skin. Some people aspirate into the syringe before they inject insulin to see whether they are hitting a blood vessel. I don't. If there is no pain when I touch the point of the needle to my skin, then I go ahead with the injection. If I can feel the prick, then I move the needle sometimes as little as 1/8 of an inch (half a centimeter) and try again.
