Recurrent Miscarriage


It is known that overall 15% of all recognized pregnancies end in miscarriage. Recurrent miscarriage is diagnosed when a woman miscarries 3 consecutive times, before 20 weeks gestation. 


What factors make one prone to recurrent miscarriage?


  •     Autoimmune diseases: diseases that affect placental function and disturb early implantation. 

  •     Chromosome problems: here, both parents are fine, but when their genes are put together, an unusual gene mismatch occurs that may result in miscarriage.

  •     Genetic predispositions for thrombophilias.

  •     Maternal infections that may be passed onto the fetus.

  •     Polycystic ovarian syndrome (PCO)

  •     Thyroid hormone imbalances.



What laboratory investigations can be done?


  •     Autoimmune tests: ANA, Cardiolipin Antibodies, Lupus

  •     Anti-coagulant and TPO.

  •     Chromosomal testing: parental blood karyotyping  and (fetal miscarriage tissue where applicable).

  •     Tests for thrombophilias: Factor V Leiden, Factor II, MTHFR.

  •     Tests for infections: Rubella, CMV, Hepatitis B and C.

  •     Hormone profile for PCO: free testosterone and LH.

  •     Thyroid testing: TSH, T3, T4 and TPO.

  •     Blood group test for Rh factor compatibility for parents.
