Carcinoembryonic antigen-related cell adhesion molecule 1 (biliary glycoprotein) (CEACAM1) also known as CD66a (Cluster of Differentiation 66a), is a human glycoprotein, and a member of the carcinoembryonic antigen (CEA) gene family.
Carcinoembryonic antigen (CEA) describes a set of highly-related glycoproteins involved in cell adhesion. CEA is normally produced in gastrointestinal tissue during fetal development, but the production stops before birth. Consequently, CEA is usually present at very low levels in the blood of healthy adults (about 2–4 ng/mL). [2]
References range may vary with age, sex, race, pregnancy, [10] diet, use of prescribed or herbal drugs and stress. Reference ranges often depend on the analytical method used, for reasons such as inaccuracy , lack of standardisation , lack of certified reference material and differing antibody reactivity . [ 11 ]
Pregnancy-specific beta-1-glycoprotein is a major product of the syncytiotrophoblast in the placenta, reaching concentrations of 100 to 290 mg/L at term in the serum of pregnant women. [ 3 ] [ 12 ] PSGs are synthesized through a gene's coding for a specific protein.
Progesterone causes many changes to the genitourinary system. A pregnant woman may experience an increase in the size of the kidneys and ureter due to the increase blood volume and vasculature. Later in pregnancy, the woman might develop physiological hydronephrosis and hydroureter, which are normal. [33]
A pregnancy test is used to determine whether a female is pregnant or not. The two primary methods are testing for the female pregnancy hormone (human chorionic gonadotropin (hCG)) in blood or urine using a pregnancy test kit, and scanning with ultrasonography. [1] Testing blood for hCG results in the earliest detection of pregnancy. [2]
The normal range of AFP for adults and children is variously reported as under 50, under 10, or under 5 ng/mL. [ 21 ] [ 22 ] At birth, normal infants have AFP levels four or more orders of magnitude above this normal range, that decreases to a normal range over the first year of life.
Pregnancy zone protein (PZP), also known as the pregnancy-associated α 2-glycoprotein (α 2-PAG or PAα 2 G), [5] is a protein which in humans is encoded by the PZP gene on chromosome 12. [6] PZP is part of the alpha-2 globulin family of proteins. [7] It is often associated with pregnancy, during which it can be the most abundant among the ...
