PUBS is an invasive diagnostic test that can be done during the second trimester of pregnancy for individuals that are looking to identify or are at higher risk of passing chromosomal and/or blood abnormalities. The demand for cordocentesis tests is diminishing because it has been replaced with CVS and Amniocentesis, which carry less risk.
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 used instead.
Anatomy scan of the fetal head at 20 weeks of pregnancy in a fetus affected by spina bifida. In the axial scan the characteristic lemon sign and banana sign are seen. Anatomy scan with power bi-directional colour Doppler of both fetal kidneys at 18 weeks of pregnancy to detect renal agenesis. The videoclip shows a frontal scan with normal renal ...
Percutaneous umbilical cord blood sampling (PUBS), also called cordocentesis, fetal blood sampling, or umbilical vein sampling is a diagnostic genetic test that examines blood from the fetal umbilical cord to detect fetal abnormalities. [1] Fetal and maternal blood supply are typically connected in utero with one vein and two arteries to the fetus.
Prenatal diagnostic testing, which includes amniocentesis, is necessary to conclusively diagnose the majority of genetic disorders, with amniocentesis being the gold-standard procedure after 15 weeks' gestation. [3] In this procedure, a thin needle is inserted into the abdomen of the pregnant woman. [4]
Some abnormalities detected by ultrasound can be addressed by medical treatment in utero or by perinatal care, though indications of other abnormalities can lead to a decision regarding abortion. Perhaps the most common such test uses a measurement of the nuchal translucency thickness ("NT-test", or "Nuchal Scan").
Non-gastrointestinal symptoms of coeliac disease may include disorders of fertility, such as delayed menarche, amenorrea, infertility or early menopause; and pregnancy complications, such as intrauterine growth restriction (IUGR), small for gestational age (SGA) babies, recurrent abortions, preterm deliveries or low birth weight (LBW) babies.
Disease testing: Whether the sex of the fetus is male or female allows the determination of the risk of a particular X-linked recessive genetic disorder in a particular pregnancy, especially where the mother is a genetic carrier of the disorder. [41] Preparation, for any sex-dependent aspects of parenting. [citation needed]
