Where are some places to check for STDs that have results within 1-2 hours? What's the usual cost? I want to do this for me and my partner.

What is the significance of 1-2 hours? For the most accurate results a few tests require a 48 hour growth culture.

a health clinic or hospital might be a good place to try

prob take a day or two for results. However prob put you on some meds for whatever symptoms you describe.

Where are some places to check for STDs

I'd advise checking the genital area first.

'where to check for STDs?'

mmm......let me think.......how about mcdonalds?

'i'll have a big mac and a chlamydia screening please'.

Is this a serious post? A hospital would be a good start. There is a hospital on Rama 4 where you can get a full check up for about 1500 baht.
