Anticardiolipin antibodies levels in healthy pregnant and non-pregnant woman

To determine the prevalence of anticardiolipin antibodies in healthy non pr egnant women and during normal pregnancy, 110 healthy women of mean age 25 years old and 53 healthy pregnant females of mean age 24.5 years old, who n o one suffered from any autoimmune disease, were studied. In all women the anticardiolipin antibodies were measured in duplicate by the Enzyme Linked Immunosorbent Assay (ELISA). There was no difference in the percentage of t he positive anticardiolipin antibodies between non pregnant and pregnant he althy women (9.1% and 5.6% respectively). Also, there was no difference in the antibodies levels during normal pregnancy, as well as, during an equal time of observation in non pregnant women. The positive anticardiolipin ant ibodies levels were low.
