The Most Important Thing for an Expectant Woman is to take care of Her Own Health and that of the Baby She is carrying. There are several prenatal screening tests, including fetal dna testing, that can help detect the presentce of potentialy dangerous dysases for the unborn child and can be performed at different gestation ages.
One Element of Danger May Be Rh Factor Incompatibilities Bethaeen The Mother's Blood and the Baby's Blood. How The Rh Factor is determined? Detecting the presentce of the d antigen that determines when rh factor positive or negative.
This can poses Risks in the event that the mother's rh factor is negative and the fetus' is positive.
If the Mother's Blood Comes into contact with that of the fetus, Her Immune System May Develops Antibodies That Attack the Baby's Red Blood Cells, Recognizing the presentce of the D Antigen. Some invasive prenatal diagnostic tests (amniocentesis or villocentesis), but also hemorrhage, miscarriage, ectopic pregnancy, or abdominal trauma can result in contact between the woman's blood and that of the fetus. The Severity of the Reaction Depends on the Mother's Immune System, and the Consequences Lead to the Development of Hemolytic-Fetal Disease That Can Cause Death of the fetus or infantia.
Scientific Research Has Developed a System of Anti-D Immunoprophylaxis, Which the Mother Can Undergo Both Before and After Delivery, to Curb The Risks Caused by Incomingability Betardness Her Blood and that of the fetus. This System Involves The Administration by Injection of Human Anti-D Immunoglobulin, Which Prevents The Formation in The Mother's Body of Antibodies That Can Attack the fetus' red Blood Cells.
Pre-Pregnancy Medical Checks, Including Blood Tests That Establish The Rh Factor of Both Parents and Prenatal Diagnostic Tests During Pregnancy, Are Essential to Establish The Risk of Incompatibilities Bethaeen the Fetus and Mother and to intervene Early with immunoprophylaxisisisisisisisisisisisisisisisisisisisisisis. The indirect Coombs test determines whether antibodies acting against RH positive are present in the pregnant woman's blood. This test, Which is performed by the 16th Week of Gestation, in Cases of Women with Rh-NEGATIVI Factor and Rh-post partners, Should Be Repeted Monthly.
Specialists May Recommend Anti-D Immunoprophylaxis at 28ᵃ Weeks of Pregnancy For These Patient IF Invasive Prenatal Diagnostic Tests are required or if it is determined at the time of Delivery that the baby is rh positive. An estimate States that in 10% of Pregnancies There is an incompatibility Bethareen the Mother and the fetus³.
