To have the kind of blood tests you discuss you would need to contact a laboratory. As you mention, most offer a postal service, however you may be able to contact them directly.
Some private hospitals will do in-depth blood tests, but they require you to have been seen by the dietician. You might like to try contacting your local private hospital and ask if they have an option for phlebotomy only appointments using self-referral.
We hope this helps, in the meantime;
