P is the position of the planet at any time, and we call r the radius vector FP. The angle AFP between the pericentre and the position P of the planet is the anomaly called v.

One of the most common reasons for performing amniocentesis is an abnormal alpha-fetoprotein (AFP) test.

A simple blood screening, usually conducted around the 15th week of pregnancy, can determine the AFP levels in the mother's blood.

Because this test has a high false-positive rate, another test such as amnio is recommended whenever the AFP levels fall outside the normal range.

Alpha fetoprotein (AFP)-A substance produced by a fetus' liver that can be found in the amniotic fluid and in the mother's blood.

The alpha-fetoprotein (AFP) test is a blood test that is performed during pregnancy to screen the fetus for certain conditions; it is also used to screen for certain diseases in infants and children.

The screening test measures the level of AFP in the mother's blood and indicates the probability that the fetus has one of several serious birth defects.

The level of AFP can also be determined by analyzing a sample of amniotic fluid.

In infants and children, the AFP test is used to detect liver disease, certain cancerous tumors, and to monitor the progress of cancer treatment.

After birth, the infant's liver stops producing AFP; an adult liver contains only trace amounts.

During pregnancy, the fetus excretes AFP in urine, and some of the protein crosses the fetal membranes to enter the mother's blood.

The level of AFP can then be determined by analyzing a sample of the mother's blood.

By analyzing the amount of AFP found in a blood or amniotic fluid sample, doctors can determine the probability that the fetus is at risk for certain birth defects.

It is very important that the doctor know precisely how old the fetus is when the test is performed, because the AFP level changes over the length of the pregnancy.

Abnormally high AFP may indicate that the fetus has an increased risk of a neural tube defect, the most common and severe type of disorder associated with increased AFP.

If the tube that becomes the brain and spinal cord does not close correctly during fetal development, AFP may leak through this abnormal opening and enter the amniotic fluid.

This leakage creates abnormally high levels of AFP in amniotic fluid and in maternal blood.

If the maternal screening test indicates an abnormally low AFP, amniocentesis is used to diagnosis the problem.

Abnormally low levels of AFP can also occur when the fetus has died or when the mother is overweight.

Although AFP in human blood gradually disappears after birth, it never disappears entirely.

The AFP test is used to screen people at high risk for these conditions.

Since an AFP test is only a screening tool, more specific tests must follow to make an accurate diagnosis.

There is no specific physical preparation for the AFP test.

An AFP level less than or equal to 50 ng/mL is considered normal.

Again, the test has a high rate of showing an abnormal AFP level in order to prevent missing a fetus that has Down syndrome.

In neonatal liver disease testing, an AFP level greater than 40 ng/mL is considered abnormal.

An AFP level greater than 20 ng/mL may be associated with tumors of the ovary or testes.

At 14-17 weeks of pregnancy, measurements of a substance called AFP (alpha-fetoprotein) can be performed.

Carrying a baby with Down syndrome often causes AFP to be lower than normal.
