Anxiety about getting hiv infection.

Hi, doctor yesterday I went for blood suger check random.though I m not diabetic. Nursing staff I found were lazy..At time i reached to their room they were having snacks .One of them went in room and bring a box of cotton.otherone doing some file work while eating. Then they merely wash their hand and pricked my finger with blood suger test. Only I assured was they tore lancet paket in front of me that is new.but other I m not sure whether they washed their hand or not and secondly they placed lancet on counter table where Lynch box was kept.and table was not fully visible to me . Now I want to know what r the chance of getting hiv infection.if they didn't clean their hand properly.or may have table some blood drop.which is touched to lancet top point.is lancet priked is direct access to blood stream.only I can say they tore new packed packet of lancet in front of me.i m worry about either their hand or table on which they kept lancet may have blood which is not visible to me.thsnks
