Affordable STI/HIV testing in Hanoi?

Hey everyone, I'm looking for a place in Hanoi where I can get an STI/HIV check-up without spending too much 😭

Ideally somewhere that:

- is reasonably affordable

- is used to dealing with sexual health/STI testing

- doesn't make the whole experience unnecessarily awkward

I've seen people mention both hospitals and smaller clinics, but I'm not sure which option makes more sense. Would appreciate any recommendations or experiences. Thanks!
