Procalcitonin in amniotic fluid at the time of genetic amniocentesis and preterm delivery.

Purpose: Procalcitonin (PCT) is an acute-phase protein that has been infrequently studied in amniotic fluid. We sought to determine if PCT levels measured in amniotic fluid samples at the time of genetic amniocentesis are predictive of preterm delivery.

Materials And Methods: A retrospective cohort study was performed on all women presenting for genetic amniocentesis between 15-23 weeks of pregnancy at our institution from 2011 to 2013 with stored amniotic fluid samples.
