PAPP-A test is one of the three tests conducted during the first few weeks (11 to 14 weeks) of pregnancy, also referred to as the first-trimester screening.

Plasma volume increases to a significant extent early in pregnancy. Maternal blood volume expansion of 40% is not unusual in singleton pregnancy and may be even greater in multiple gestations. This expansion in blood volume is due to an increase in plasma volume of 45% to 55% and an increase in red cell mass of 20% to 30%.

Jul 15, 2006 · During pregnancy, constituents of CS lead to myriad effects on plasma Nic concentrations due to the gestational-dependent and tissue-specific induction and inhibition of metabolizing enzymes, hormonal changes, including competitive progesterone binding sites, an increase in blood volume, and development of placental and fetal compartments ...

Plasmapheresis is a medical procedure designed to remove some plasma from the blood. During a plasma exchange, unhealthy plasma is swapped for healthy plasma or a plasma substitute, before the blood is returned to the body. The blood vessels contain plasma. It is a fluid made up of blood cells, platelets, and essential nutrients.
