Other tests of placental function
Many test have been shown to be of no value in assessment of placental function and are of historical value only. These include serial estriol estimation, human placental lactogen assays, contraction cardiotocography (CTG) stress testing and monitoring daily fetal movements. Measuring serial fundal height is of value in selecting woman for referral to ultrasound screening. Doppler assessment combined with non-stress CTG may be important in diagnosing and managing IUGR(Ott 2006).
