Hi Have you looked on Blue Horizon site, main site?. Do not go through a private hospital, finger prick or venous blood. All by post.
However If , as I suspect that is for cortisone,my good Endo says the only test any use is 24 hour urine collection with a cortisone tablet at midnight, script, and a blood test at 9 am. As you can see , this is not possible for DIY.
B.H do do all the NHS tests and many more, also some are better.
