Freya, some of the tests I had were -

ANA - Anti-Nuclear Antibody, anticardiolipin ab, antithrombin 111, karyotype, lupus anticoagulant, protein C and S, prothrombin gene mutation, factor V leiden/APC resistance, CA125, Thyroid Stimulating Hormone, Prolactin, Progesterone, Oestradiol, Luteinising Hormone, FSH, SHGB, Glucose (fasting), insulin fasting, DHEAS, 17 hysroxyprogesterone, sensitive testosterone.

As I said, I don't have issues with miscarriage, rather failure to conceive (even though my embryos look fine).
