1. Alpha fetoprotein (AFP)
This is a protein the blood level of which is measured by laboratory methods. Its level is elevated in the mother's blood when there are fetal spinal cord defects (anencephaly, myelomeningocele), threatened abortion, twin gestation, and abruptio placentae. The AFP screening test for the mother's blood is usually conducted at 16 - 18 weeks of pregnancy. AFP level in the amniotic fluid obtained in amniocentesis is measured to identify abnormal fetal development. In humans, AFP is a useful marker for the diagnosis and assessment of the tumors of the testis (teratocarcinoma and embryonal carcinoma). AFP is also elevated in patients with primary liver cancer (hepatocellular carcinoma) and in women with some types of germ cell ovarian tumors. (Normal range: less than 40 micrograms per liter).

2. Alpha-fetoprotein
The fetal equivalent of albumin .

3. Amniocentesis
A technique for testing the genetic health of a fetus by inserting a needle through the mother's abdominal wall into the uterus and extracting a small amount of the amniotic fluid, the fluid that surrounds the fetus. Sloughed-off fetal cells ( fibroblast s) found in this fluid are then cultured and their DNA examined for defects. This procedure is done in the second trimester, and because of the time needed to do the culture, results aren't generally available until after the 20th week of pregnancy.

4. Amniocentesis
A method of prenatal testing in which amniotic fluid is withdrawn from the uterus through a needle. The fluid and the fetal cells it contains are analyzed to detect biochemical or chromosomal disorders.

5. Anti-phospholipid syndrome
Anti-phospholipid syndrome is an autosomally inherited genetic disorder in which an affected individual produces antibodies against his/her own cellular phospholipid components. This is manifested clinically as a tendency to have arterial and venous thrombosis , thrombocytopenia and recurrent fetal loss (miscarriage).

6. Chorionic villi sampling (CVS)
A method of prenatal testing in which fetal cells from the fetal side of the placenta (chorionic villi) are extracted and analyzed for chromosomal and biochemical defects.

7. Cryptorchidism (undescended testes)
Cryptorchidism is the condition in which one or both testes fail to descend into the scrotum during the fetal or infant period. If both testes are involved, sperm are not formed and the patient is fertile. There is also a higher incidence of testicular cancer for an undescended testicle.

8. Diethylstilbestrol (DES)
A synthetic estrogen (originally prescribed to prevent miscarriage) that caused malformations of the reproductive organs in some who were exposed to the drug during fetal development.

9. Erythroblastosis fetalis
A type of anemia which can occur in newborns that have Rh+ blood and which are born to mothers with Rh- blood (see Rh factor ). Symptoms include lots of erythroblast cells which are circulating in the blood instead of being within bone marrow, liver and spleen enlargement, and edema (tissue swelling due to excessive fluid).

10. Erythroblastosis fetalis
Erythroblastosis fetalis is the condition in which a pregnant women produces an antibody (IgG) to the red blood cells of the fetus she is carrying, which causes the destruction of her fetus' red blood cells. This condition is worse in successive at-risk pregnancies. The antigens could be Rh (most commonly RhD), Kell, Duffy, Lutheran, and Kidd. The mother whose pregnancy is at risk is negative for these antigens.
