"Blood tests without gloves!"

18.06.2015 I had a blood test. Person before me had a blood test, doors was open so I could see inside the room. Nurse that was taking blood was not wearing gloves during the tests. Next person was me. I'm always scared of blood test, so I don't know why I let do blood test on me this nurse. The nurse did not clean my skin before the test, the nurse touched me with their finger without gloves, and did the whole treatment without gloves. I did not say anything probably because the nurse was a nice person and was talking to me, but now I'm scared that because of this nurses mistakes I might have some serious disease.
