Obstetric ultrasonography, or prenatal ultrasound, is the use of medical ultrasonography in pregnancy, in which sound waves are used to create real-time visual images of the developing embryo or fetus in the uterus (womb).
Biophysical profile. A biophysical profile ( BPP) is a prenatal ultrasound evaluation of fetal well-being involving a scoring system, [ 1] with the score being termed Manning's score.[ 2] It is often done when a non-stress test (NST) is non reactive, or for other obstetrical indications. The "modified biophysical profile" consists of the NST ...
chromosomal abnormalities. The triple test, also called triple screen, the Kettering test or the Bart's test, is an investigation performed during pregnancy in the second trimester to classify a patient as either high-risk or low-risk for chromosomal abnormalities (and neural tube defects). The term "multiple-marker screening test" is sometimes ...
Anomaly scan. The anomaly scan, also sometimes called the anatomy scan, 20-week ultrasound, or level 2 ultrasound, evaluates anatomic structures of the fetus, placenta, and maternal pelvic organs. This scan is an important and common component of routine prenatal care. [ 1] The function of the ultrasound is to measure the fetus so that growth ...
Nuchal translucency. Purpose. Used to screen for abnormalities in a developing fetus. A nuchal scan or nuchal translucency ( NT) scan / procedure is a sonographic prenatal screening scan ( ultrasound) to detect chromosomal abnormalities in a fetus, though altered extracellular matrix composition and limited lymphatic drainage can also be detected.
Elevated alpha-fetoprotein refers to a state where alpha-fetoprotein levels are outside of the reference range. There are two categories of AFP tests: tests performed on serum (blood plasma), and tests performed on amniotic fluid. Tests performed on serum are further categorized by the reason for performing the test: maternal serum, adult tumor ...
Gravidity and parity. In biology and medicine, gravidity and parity are the number of times a female has been pregnant (gravidity) and carried the pregnancies to a viable gestational age (parity). [ 1][ 2] These two terms are usually coupled, sometimes with additional terms, to indicate more details of the female's obstetric history. [ 3]
A pregnancy test is used to determine whether a female is pregnant or not. The two primary methods are testing for the female pregnancy hormone ( human chorionic gonadotropin (hCG)) in blood or urine using a pregnancy test kit, and scanning with ultrasonography. [ 1] Testing blood for hCG results in the earliest detection of pregnancy. [ 2]
