cord blood puncture

Umbilical cord blood puncture is one of the important prenatal examinations. Puncture is an irreplaceable role in the diagnosis and development of the fetus in the abdomen. Umbilical cord blood puncture and amniocentesis chromosome examination can check whether the fetal spine is deformed. The umbilical cord puncture depends on the position of the placenta to determine the location of the puncture. It can puncture the part that is free in the amniotic fluid, or puncture the umbilical cord at the root of the fetus or at the root of the placenta. Most choose to puncture the umbilical vein. The method is basically the same as amniocentesis, except that the puncture site is different. Basic Information Specialist classification: maternity check check classification: blood test Applicable gender: whether women are fasting: fasting Analysis results: Below normal: Normal value: no Above normal: negative: The baby is developing normally. Positive: Prompt fetal dysplasia, chromosomal abnormalities. Tips: Actively cooperate with the doctor's work. Normal value The fetus is well developed, the body is well-proportioned, and the genetic characteristics are stable and negative. Clinical significance Abnormal result Fetal malformations, chromosomal abnormalities, fetal dysplasia, etc. People who need to be checked Pregnant women and people who need to have a fetal development check. Positive results may be diseases: mother and child ABO blood group inconsistency Taboo before the examination: poor rest, improper diet, excessive fatigue. Requirements for inspection: Actively cooperate with the doctor's work. Inspection process Usually, the cord blood is first centrifuged, and then: (1) the supernatant is taken for biochemical assay to monitor fetal maturity or to find certain congenital malformations, especially neural tube defects, such as no brain, hydrocephalus, etc.; (2) Progressive chromatin examination, chromosome analysis and biochemical determination of enzymes to predict or determine the sex of the fetus, and to help diagnose chromosomal abnormalities of hereditary diseases and congenital metabolic defects. Not suitable for the crowd Adverse reactions and risks No complications.
