AFP is normally elevated in infants, and because teratoma is the single most common kind of tumor in infants, several studies have provided reference ranges for AFP in normal infants. [5] [6] [7] Perhaps the most useful is this equation: log Y = 7.397 - 2.622.log (X + 10), where X = age in days and Y = AFP level in nanograms per milliliter. [8]
It is a tetramer protein with 2 alpha and 2 gamma subunits. This is different from adult hemoglobin because it has 2 alpha and 2 beta subunits. Fetal hemoglobin is coded by a gene on chromosome 11. The gamma subunit on fetal hemoglobin contains a neutral and nonpolar amino acid at position 136, unlike the beta subunit of adult hemoglobin.
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 ]
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 ...

This is typically seen as a broadening of the alpha-2 zone. Alpha-2 macroglobulin may be elevated in children and the elderly. This is seen as a sharp front to the alpha-2 band. AMG is markedly raised (10-fold increase or greater) in association with glomerular protein loss, as in nephrotic syndrome. Due to its large size, AMG cannot pass ...

It is composed of two α (alpha) subunits and two γ (gamma) subunits, whereas hemoglobin A (97% of total hemoglobin in adults) is composed of two α and two β (beta) subunits. In humans, the α subunit is encoded on chromosome 16 and the γ subunit is encoded on chromosome 11. There are two very similar genes that code for the α subunit ...
