What is LIT?

Lymphocytes (white blood cells) of two classes are isolated from the male spouse. The two classes isolated from whole blood are the T cells (CD-3) and the B cells (CD-19). Forty million lymphocytes are washed three times and concentrates into an immunization. This concentrate of Lymphocytes is then injected in the skin of the woman (intradermally) just like an allergy skin test.

The injected areas then become red, slightly swollen and itch just like a positive skin test.

One month later the process of the injections are repeated. The second injection sites usually become  less red, swollen and itch less than the first ones. One month later blood is drawn from the woman and blood is drawn from the man. a test called lymphocyte antibody detection assay is done to determine if the immunizations have worked and the woman has made blocking antibody to her spouse's T and B cells.
