I had a rather small cut on the palm of my hand. Turns a splinter was stuck in there,, so it wouldn't fully close. I ended up going to the doctor and he was able to push/tweeze it out. I noticed that the cut began to close after that. Roughly 4 days later I was out with some friends at a restaurant and there was a line for the bathroom. When it was my turn, I usually always wash my hands before I use the bathroom so I hit the soap dispenser button with the same palm that I have that cut (dumb I know). And I noticed something kind of sticky on the button... I have no idea what it is, but worst case scenario let's say it is blood. Is this something I should get tested for? Especially since it was literally seconds from when the last person touched it (once again assuming it was blood)

Side note- since I was pushing the button, I ended up washing my hands with soap almost immediately after feeling the sticky substance, not sure if this helps/changes the situation. 

My cut wasn't actively bleeding at the time and it was in the healing process. I would say the cut itself looked to be a bit bigger than a tip of a pencil.

Thanks for your time

Our experience and expertise are in STIs and sexual transmission -- we certainly are not experts in nonsexual transmission. However, I see nothing in this description that suggests any risk for HIV, the hepatitis C virus (HCV), or anything else. I would not advise testing; you really shouldn't be at all worried.

I hope these comments are helpful. Let me know if anything isn't clear.
