Why immune testing for patients with repeated IVF failures and repeated miscarriages is a waste of time and money

Patients who have failed repeated IVF cycles even though apparently perfect embryos were transferred, are understandably upset, frustrated and distressed. They are looking for answers as to why they are not getting pregnant, and a plausible reason is that their body is "rejecting" their embryos. This is why immune testing for patients with reproductive failure has become very fashionable recently. There is a long list of expensive tests which many labs now perform - and these include: DQ Alpha, Leukocyte Antibody Detection, Reproductive Immunophenotype, ANA (Antinuclear Antibody), Anti-DNA/Histone Antibodies, APA (Antiphospholipid Antibodies), Natural Killer ( NK) Cell Assay and TJ6 Protein. This mind -boggling range of catchy acronyms conceals the fact that no one knows whether the immune system is really responsible for the failure of the embryos to implant in these women. Many labs use different protocols to carry out these tests, which are still poorly standardized. This means that results for the same test from different labs vary widely, making interpretation very difficult. Also, intelligently interpreting these tests in individual patients is virtually impossible, because of the considerable overlap in the results in normal fertile women and those who are infertile, since many fertile women will also have abnormal results when subjected to these tests. Sadly, most labs do not bother to standardize their test results by doing them on normal fertile women...
