I cut my finger and may have been exposed to HIV, should I be tested?

Hello,

I am currently a paramedic student working in South Africa. I had an incident when changing over a fluid bag on a patient. When changing the fluid bag I cut my finger on the spike near the top that punctures into the fluid bag. I noticed that blood had started to move slightly up the IV line but not all the way up.

I also had blood on my gloves at this stage. Although I cut my finger it was a tiny paperlike cut that only slightly bled if even at all.

I am now really anxious about contracting HIV is this at all possible. Should I be tested? Or does my incident not warrent as a method of transmission

I’d appreciate any advice. Thank you
