What does Cordocentesis mean to you? how does it work and where can be applied in?

:That's mean for me

Cordocentesisknown as percutaneous umbilical blood sampling

Definition:  is a highly specialized prenatal test in which a sample of the baby's blood  is a highly specialized prenatal test in which a sample of the baby's blood is removed from the umbilical cord for testing.

Cordocentesis might be offered when:

The desired information can't be obtained any other way

Results from other prenatal tests are unclear

Test results might have a significant impact on the immediate management of the pregnancy

Sampling

Chorionic villus sampling (CVS) sampling of chorionic villi from the villous area of the chorion, a procedure used for prenatal diagnosis at nine to12 weeks of gestation. A catheter is inserted either through the cervix or through the abdominal wall and fetal chorionic villus tissue for analysis is aspirated under ultrasonic guidance. This is used for the prenatal diagnosis of fetal trisomies, hemoglobinopathies, & biochemical disorders. It allows first trimester diagnosis and direct chromosomal & biochemical analysis but does not screen for neural tube defects or certain other anomalies; some of those may be identified by maternal serum and amniotic fluid AFP measurements.

Percutaneous umbilical blood sampling a procedure used to obtain fetal blood for examination; a sterile needle is inserted through the mother's abdomen and uterus, and guided to one of the umbilical veins via ultrasound. This procedure has begun to replace fetoscopy because it has a lower complication rate. Direct sampling of fetal blood provides more rapid test results than amniocentesis, and a more definitive diagnosis. It can be used to identify chromosomal abnormalities, detect a fetal infection, & assess fetal growth & development. Called also cordocentesis.

1. Cordocentesis also called as Percutaneous umblical cord blood sampling is diagnostic test that examines blood from the fetus to detect fetal abnormalities.
2. Its usually performed after 17 weeks of pregnancy 
3. Indications- Karyotype to detect fetal anomaly, Alloimmunisation, metabolic and hematological status of fetus
