Follow up: Upon receiving maternal serum screening results, all information used in the risk calculation should be reviewed for accuracy (ie, weight, diabetic status, gestational dating, etc.).

Subsequently, the AFP reaches the maternal circulation; thus producing elevated serum levels.

Other fetal abnormalities such as omphalocele, gastroschisis, congenital renal disease, esophageal atresia, and other fetal distress situations such as threatened abortion and fetal demise also may show AFP elevations.

In particular, erroneous assessment of gestational age can result in false-positive or false-negative screen results.

Because of its increased accuracy, we therefore recommend determination of gestational age by ultrasound, rather than by maternal dates alone when possible.

A screen-positive result indicates that the calculated AFP Mo M is or =2.50 Mo M and may indicate an increased risk for open NTDs.

The actual risk depends on the level of AFP and the individual's pre-test risk of having a child with NTD based on family history, geographical location, maternal conditions such as diabetes and epilepsy, and use of folate prior to conception.

Analytes: Alpha-fetoprotein (AFP) is a fetal protein that is initially produced in the fetal yolk sac and liver.

A small amount also is produced by the gastrointestinal tract.

A screen-positive result does not infer a definitive diagnosis of a NTD, but indicates that further evaluation should be considered.

Approximately 80% of pregnancies affected with an open NTD have elevated AFP Mo M values 2.5.

Race, weight, multiple fetus pregnancy, and insulin-dependent diabetes (IDD) may affect marker concentrations.
