Amniocentesis is performed to assess fetal lung maturity in the event of a preterm birth.Indications for PUBS include prenatal diagnosis or inherited blood disorders,karyotyping of malformed fetuses,detection of fetal infection,determination of the acid-base status of the fetus with intrauterine growth restriction (IUGR),and assessment and treatment of isoimmunization and thrombocytopenia in the fetus.Determination of fetal size by ultrasound typically is done during the second trimester and is not indicated in this scenario.An NST measures the fetal response to fetal movement in a noncontracting mother.
