Hospitals will often use a non-alcohol based disinfectant, as the trace amounts of alcohol can affect some blood tests (like blood alcohol content for example).

To prevent infection of the wound AS WELL AS the sample being taken. The skin contains soo many native flora that they can easily contaminate a sample when the needle pierces the skin. So there are actually two reasons.

70% isopropol alcohol kills germs as it dries. So if they rub it on and stick you right away, it didn't do anything. But if they let it dry, it kills most of the germs there so they don't go in with the needle.

Disinfecting the skin so the needle won't push germs into your circulatory system.

To remove bacteria and to clean the spot where they are going to inject you. This is to prevent infection.
