What is fetal blood?

Fetal blood or fetal hemoglobin is the blood that circulates in the fetus since the child is about two months of pregnancy. The same type of blood remains in a newborn baby until he is about six months old. It has certain features adapted to suit the specific needs of the fetus and the child. Some blood disorders, such as anemia of sickle cells, may be influenced by this special form of human hemoglobin.

Because the fetus receives all its oxygen and nutrients from the blood of its mother for the duration of pregnancy, this gestational blood is more effective in processing oxygen than the blood that they later cause in life. It contains about 50% more hemoglobin, which is a protein in red blood cells that circulate oxygen. This hemoglobin is able to hold 20 to 30% more oxygen than normal blood. The main vein of the umbilical cord, called the umbilical vein, gains blood rich in oxygen from the mother to the placenta and the fetus.

As soon as the baby is born, fetal blood is reduced to 50%. Continues to reduceup to about six months of age when it is completely replaced by typical human blood. This process occasionally fails and fetal blood continues to be the main type of blood circulated throughout the system well for childhood and adulthood. This is known as hereditary persistence of fetal hemoglobin (HPFH). It has no known symptoms and usually occurs only when testing other blood diseases. The condition is particularly prevailing in people of African and Greek heritage.

Another anomaly that may occur when fetal blood blood changes is an indicator of sickness cells , sometimes called sickle cell anemia . Instead of producing adults or typical blood after six months like most children, people with sickle-shaped diseases make the hemoglobin with a form of hemoglobin that have red blood cells that have a round shape. This abnormality usually leads to a period of intense pain. If a person suffering from sickle cells has a predominance of hemoglobin insteadFetal blood, pain is less intense and episodes are less common. Therefore, a synthetic drug is called hydroxyurea often used to produce more blood fetus to treat these episodes.

Fetal blood can be sampled in the uterus for various blood diseases. This process is considered an outpatient surgery. Using an ultrasonic machine, the doctor inserts the needle through the mother's fuselage and into the umbilical cord. The blood is taken with a needle and then tested for anemia and other problems.
