I said they encouraged users of the service to make a list of previous partners. This wasn't supposed to be disclosed to anyone. It's just for the purposes of the user - presumably to reflect upon their sexual history, or maybe if there were anything untoward found in the subsequent test results.
And it was just the usual swab up the japs eye, no teaspoon required; thanks for your interest.
as Pedant says there, they will ask you non-specific questions about numbers. and your STI test results are confidential, hence why you only get referred to by a reference number, and they wont go contacting any of your previous sexual partners either if they find anything, they will just contact you alone, the responsibility is up to you then whether or not to inform your previous sexual partners.
