I work in the health care field and recently(2 days ago) I grabbed a cup with bloody urine( the cup was covered) but there was alot of blood in this urine and when I grabbed the cup I didn't have gloves on and I grabbed it with my thumb and my middle finger. Later I noticed that I had a hang nail and my thumb. Now I don't recall if there was some urine on the outside of the cup and I washed my hands afterward should I worry?
