STD Test Results

Marina❁ • 20 yrs.
So I had a doctors appointment Monday and they offered a free STD test so I said ya why not. They took blood and the phlebotomist said I also had to give a urine sample, but I took it into a lab the day after. Tuesday night my mom told me she got a call earlier that day saying my lab test results were ready, but she told them that I'm 19 and they should be calling me about it and not her. She offered to give them my cell number so they could contact me and tell me but they said no, that's okay. Just let her know they're here whenever she wants to get them.
So my question is, if it came out positive or anything, wouldn't they want to talk to me urgently? And not just say I can come get my results "whenever"?
I'm planning on going in Friday to pick up my results, but they never attempted to contact me directly. I figure if it was serious they would've at least attempted to contact me ASAP? For all they know they're not gonna see me for another 3 months when my next appointment is scheduled. Idk, just trying to ease my mind I guess 😅 It makes sense though, right?!
