Tests during pregnancy

thumb|Tubes filled with amniotic fluid for amniocentesis Amniocentesis or amniotic fluid test (AFT) is a medical procedure used primarily in the prenatal diagnosis of genetic conditions. It has other uses such as in the assessment of infection and fetal lung maturity. 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.

Fetoscopy is an endoscopic procedure during pregnancy to allow surgical access to the fetus, the amniotic cavity, the umbilical cord, and the fetal side of the placenta. A small (3–4 mm) incision is made in the abdomen, and an endoscope is inserted through the abdominal wall and uterus into the amniotic cavity. Fetoscopy allows for medical interventions such as a biopsy (tissue sample) or a laser occlusion of abnormal blood vessels (such as chorioangioma) or the treatment of spina bifida.

investigation performed during pregnancy in the 2nd trimester to check chromosomal abnormalities

genetic test

blood test measuring fetal hemoglobin transferred from a fetus to a mother's bloodstream, often performed on Rh-negative mothers to determine the required dose of Rho(D) immune globulin to prevent Rh disease in Rh-positive children

quantitative estimate of amniotic fluid

analysis of cell-free fetal DNA, or DNA from fetal cells that are biopsied from a pregnant woman’s blood

physical activity of the fetus in utero

prenatal ultrasound evaluation of fetal well-being

ultrasound performed between 18-22 weeks of gestational age

screening test used in pregnancy to assess fetal status by means of the fetal heart rate and its responsiveness
