Prenatal testing is a tool that can be used to detect some birth defects at various stages prior to birth. Prenatal testing consists of prenatal screening and prenatal diagnosis , which are aspects of prenatal care that focus on detecting problems with the pregnancy as early as possible. [ 1 ]
A number of defects can be detected before birth by different prenatal tests. [10] Treatment varies depending on the defect in question. [7] This may include therapy, medication, surgery, or assistive technology. [7] Birth defects affected about 96 million people as of 2015. [11] In the United States, they occur in about 3% of newborns. [8]
These tests don't directly detect hypoxia, but instead detects the general well-being of the baby and ensures that the baby is healthy since hypoxia causes a wide range of responses. These tests can include prenatal testing, such as fetal movement and amniotic fluid levels, Doppler examination , or fetal heart rate. [ 36 ]
Spina bifida (SB; / ˈ s p aɪ n ə ˈ b ɪ f ɪ d ə /; [9] Latin for 'split spine') [10] is a birth defect in which there is incomplete closing of the spine and the membranes around the spinal cord during early development in pregnancy. [1] There are three main types: spina bifida occulta, meningocele and myelomeningocele. [1]
An elevated MSAFP measured at 16–18 weeks gestation is a good predictor of open neural tube defects, however the test has a very high false positive rate, (2% of all women tested in Ontario, Canada between 1993 and 2000 tested positive without having an open neural tube defect, although 5% is the commonly quoted result worldwide) and only a ...
Congenital hypothyroidism (CH) is thyroid hormone deficiency present at birth. If untreated for several months after birth, severe congenital hypothyroidism can lead to growth failure and permanent intellectual disability. Infants born with congenital hypothyroidism may show no effects, or may display mild effects that often go unrecognized as ...
Maternal–fetal medicine (MFM), also known as perinatology, is a branch of medicine that focuses on managing health concerns of the mother and fetus prior to, during, and shortly after pregnancy. Maternal–fetal medicine specialists are physicians who subspecialize within the field of obstetrics. [ 1 ]
Another test that may be performed is a chromosomal microarray, which can detect chromosomal imbalances, such as small- and large-scale deletions and duplications. [8] Chromosomal microarray can be performed on cultured or uncultured fetal tissue, with results available as early as 3 days. [ 5 ]
