High

Preterm labor or women who have a high risk for preterm labor
Preterm membrane rupture
History of extensive uterine surgery or classic uterine incision for cesarean birth
Placenta previa

Contraindications of CST

Uses a real-time ultrasound for visualization of physical and physiological characteristics of a fetus

Biophysical Profile (BPP)

Requires a blood sample from the mother. It is used to detect AFP (A protein produced by the fetus at its highest levels in weeks 12-15) after the 16th week of pregnancy when levels go to zero. High levels at this point indicate a neural tube defect.
