Anemia in pregnancy is a decrease in the total red blood cells (RBCs) or hemoglobin in the blood during pregnancy. Anemia is an extremely common condition in pregnancy world-wide, conferring a number of health risks to mother and child. [ 2 ]
Cell-free DNA can be used the determine the Rh antigen of the fetus when the mother is Rh negative. Blood is taken from the mother during the pregnancy, and using PCR, can detect the K, C, c, D, and E alleles of fetal DNA. This blood test is non-invasive to the fetus and is an easy way of checking antigen status and risk of HDN.
It can therefore only be done 2–3 weeks after a hemolytic episode. [23] When a macrophage in the spleen identifies an RBC with a Heinz body, it removes the precipitate and a small piece of the membrane, leading to characteristic "bite cells". However, if a large number of Heinz bodies are produced, as in the case of G6PD deficiency, some ...
Although described as "morning sickness," pregnant women can experience this nausea any time of day or night. The exact cause of morning sickness remains unknown. Nausea and vomiting in pregnancy is typically mild and self-limited, resolving on its own by the 14th week of pregnancy. Other causes should also be ruled out when considering treatment.
A multi-center European trial studied early versus late r-EPO in 219 infants with birth weights between 500 and 999 g. An r-EPO close of 750 U/kg/week was given to infants in both the early (1–9 weeks) and late (4–10 weeks) groups. The two r-EPO groups were compared to a control group who did not receive r-EPO.

Embryonic Hb are expressed as early as four to six weeks of embryogenesis and disappear around the eighth week of gestation as they are replaced by fetal Hb. [11] [12] Embryonic Hbs include: Hb Gower-1, composed of two ζ (zeta) globins and two ε (epsilon) globins, i.e., ζ 2 ε 2; Hb Gower-2, composed of two α globins and two ε globins (α ...
Fetal viability typically occurs at about 24 to 25 weeks of gestation. [2] When the fetus is in between the ages of 24–34 weeks, a glucocorticoid is given to the patient about 24 hours before the procedure to stimulate lung maturity. An ultrasound is performed before the procedure to view the position of the fetus and may be used during the ...
