title: Serum hCG levels measured by time-resolved fluoroimmunoassay in first-trimester pregnancy and after pregnancy termination.
abstract: Time-resolved fluoroimmunoassay (TR-FIA) reliably shows the concentrations of serum hCG during the first trimester of normal pregnancy. After first-trimester induced abortion the mean disappearance of hCG in serum (under 10 IU/l) takes place in three weeks. TR-FIA is a convenient and ultrarapid method for diagnosing pregnancy-related disorders.
