Thanks for your query.
Ig - G positive for any of these infections is not important.
If the Ig - M is positive, that indicates an active infection and is a cause for abortion
Other causes of abortion like thyroid
abnormality, incompetence of uterine cervix, abnormality of uterine cavity
, genetic causes, hormonal
defects , immune causes etc should be ruled out.
Based on just this one report that you have mentioned, I do not see any reason for an abortion.
