I am 28 years old male I had visited a lab in the month of 3rd nov 2020 for normal blood test but could not notice while the blood was being drawn from syringe due to some reasons after that I was very much depressed and anxious thinking about hiv contracting through the needle if it is reused. I went to another lab in the month of dec 18 2020 and got tested for duo 4th generation ab/ag test. The result was negative after 6-7 weeks. But still I am sunk in the fear and not able to come out of this anxiety anymore kindly provide me relevant information on this if I need any more tests? What is the accuracy or is my result conclusive? I never ever had any sex nor any blood transfusion ever in my life. I am devastated both professionally and personally kindly help.
