I had a cut with a blade that had dry blood stain on bottom of it.top edge cut me.edge was clean.that blade is used for cutting plaster and bandages.I don't know from where that stain came.it was dry.
Initially it was not bleeding and then I cleaned with spirit swab then small amount of blood was oozing.
Bloos source unknown.
I was afraid
Did hiv antibody test on 22th day and antibody plus p24 test on 26th day.both came negetive.
Do I need to retest?
