Elevated alpha-fetoprotein refers to a state where alpha-fetoprotein levels are outside of the reference range. There are two categories of AFP tests: tests performed on serum (blood plasma), and tests performed on amniotic fluid. Tests performed on serum are further categorized by the reason for performing the test: maternal serum, adult tumor ...
Alpha-fetoprotein (AFP, α-fetoprotein; also sometimes called alpha-1-fetoprotein, alpha-fetoglobulin, or alpha fetal protein) is a protein [5] [6] that in humans is encoded by the AFP gene. [ 7 ] [ 8 ] The AFP gene is located on the q arm of chromosome 4 (4q13.3). [ 9 ]
In adults a normal amount of AFP is 0-40nng/mL and high levels of this can indicate diseases, cancer, and fetal defects. In pregnant people AFP levels rise at 14 weeks until 32 weeks, and range between 10 and 150 ng/mL in the middle of gestation. This is why AFP can be used alongside other tests as a tumor marker protein in adults. [12]
Alpha-fetoprotein (AFP) is significantly expressed in foetal liver. However, the mechanism that led to the suppression of AFP synthesis in adults is not fully known. Exposure of the liver to cancer-causing agents and arrest of liver maturation in childhood can lead to the rise in AFP. AFP can reach until 400–500 μg/L in hepatocellular ...
The most common abnormality the test can screen is trisomy 21 (Down syndrome).In addition to Down syndrome, the triple and quadruple screens assess risk for fetal trisomy 18 also known as Edwards syndrome, open neural tube defects, and may also detect an increased risk of Turner syndrome, triploidy, trisomy 16 mosaicism, fetal death, Smith–Lemli–Opitz syndrome, and steroid sulfatase ...

Still, Trump's nomination of Scott Bessent to the top Treasury post raised hopes that tariffs will be more measured. And with only 21 trading days left in the year, analysts, investors, and market ...
Multiple births by a woman are strongly associated with a lower risk of developing breast cancer later in her life. [3] One of the contributing factors for this association appears to be the alpha fetoprotein (AFP) produced by the fetal liver, which crosses the placenta and enters into the maternal circulation. [4]
