the investigated autoimmune panel included a search for antinuclear antibodies , autoantibodies ( in igg , igm and iga isotypes ) to seven phospholipids ( cardiolipin , phosphatidylserine , phosphatidylglycerol , phosphatidylcholine , phosphatidylethanolamine , phosphatidylinositol , and phosphatidic acid ) , to four histone subfractions ( h1 , h2a , h3 , h4 ) , and to four polynucleotides [ ssdna , dsdna , poly ( i ) , and poly ( dt ) ] , total immunoglobulin levels , and sperm antibody titers .
