Depending on the individual couple's situation, various blood tests on either the female or the male may be needed.
Blood tests that might be needed include day 3 follicle stimulating hormone (FSH), luteinizing hormone (LH), prolactin, testosterone (T), estradiol (E2), progesterone (P4), 17-hydroxyprogesterone (17-OHP), thyroxin (T4), thyroid stimulating hormone (TSH), lupus anticoagulant (LAC), anti-cardiolipin (ACL), and possibly other tests
Immunological testing has not been proven to have any value in infertility patients without a history of 2 or more miscarriages.
