If you're concerned amazon have STD testing kits that are a bit fiddly at first. Not sure if it's ok to post an amazon link here, but you can PM me if you want one. The last test I ordered tested everything except for syphilis and HIV, you'd need to get that separately. Terrence Higgins trust in Glasgow does same day (30 min) HIV tests in their Sauchiehall St (TUES nights) and East Kilbride (THURS nights) offices. You don't even need to give your real name. I never. I just made one up and used a duff GP office and ticked the box not to share info with GP. NHS Scotland use your CHI number to identify you which the Sandyford falls under, but THTrust is a charity, so different databases of information. They don't have access to your NHS notes
