title: Biochemistry in the diagnosis and management of abnormal early pregnancy.
abstract: OBJECTIVE
  To examine the current state of knowledge regarding the biochemical parameters of early pregnancy failure.
  
  
  RESULTS
  Earlier studies have concentrated on the role of human chorionic gonadotropin and progesterone in early pregnancy failure and recent studies have also explored newer markers such as the inhibins and insulin growth factor binding proteins. Multiparameter models have now been created for the prediction of successful expectant management of early pregnancy failure.
  
  
  CONCLUSIONS
  Examining the role of newer biochemical markers in the early pregnancy failure has led to an improved understanding of the underlying mechanisms and has clinical benefit in the selection of appropriate management for patients.
