There has been a lot of talks lately about immune testing and its relationship to failed IVF cycles. However, this area is understudied and fertility specialists have little knowledge of the immune system. Nevertheless, many have expensive immune tests done. For example, some of the tests include DQ Alpha, Reproductive Immunophenotype, Antinuclear Antibodies, TJ6 Protein and Leukocyte Antibody Detection. Couples should be aware that many labs do not follow standard procedures when testing and therefore the tests will never have the same result when performed in different labs. Unfortunately, this makes it difficult to interpret the data.
