The present invention provides a method of predicting pregnancy outcome in a
subject by determining the amount of an early pregnancy associated molecular isoform
of hCG in a sample. The present invention further provides a method for determining
the amount of early pregnancy associated molecular isoforms of human chorionic
gonadotropin (hCG) in a sample. The present invention also provides a diagnostic
kit for determining the amount of early pregnancy associated hCG in a sample. The
present invention additionally provides an antibody which specifically binds to
an early pregnancy associated molecular isoform of human chorionic gonadotropin.
Finally, the present invention provides methods for detecting trophoblast or non-trophoblast
malignancy in a sample.
