Devices for individual use at home detect pregnancy by measuring levels of the hormone human chorionic gonadotropin (hCG) in urine.
In prenatal medicine, ultrasonography is a valuable tool used to monitor the health and development of a fetus. By using high-frequency sound waves to create graphic images, clinicians can gather essential information regarding fetal growth and anatomy.1
Key insights provided by an ultrasound include:
- Growth Assessment: Ultrasound is used to estimate gestational age by taking specific measurements of the fetal head and abdomen.21
- Anatomical Survey: It allows for a general survey of fetal anatomy and can help identify heart activity and potential heart defects.31
- Developmental Status: The procedure provides information on the morphological and functional status of the fetus.1
- Additional Observations: Beyond the fetus itself, ultrasound helps determine the fetal number, the presentation of the fetus, the position of the placenta, and the volume of amniotic fluid.1
While ultrasound is widely used to ensure a fetus is healthy, it is important to note that its routine inclusion in standard prenatal care remains a subject of discussion in some regions due to the ongoing evaluation of its long-term safety profile.31
