Chorionic villus test is chorionic villus cell test, which is a test mainly for pregnancy, and can initially diagnose the presence of hemophilia.
Chorionic villus testing is a chromosome screening test on placental villus tissue, which can detect chromosomal disorders, such as trisomy 21, trisomy 18, thalassemia, and also initially diagnose the presence of hemophilia.
Hemophilia is a hereditary disease. Genetic analysis of chorionic tissue and prenatal testing can determine whether a fetus is hemophiliac.
High-risk pregnant women with a family history of hemophilia should be diagnosed as carriers of the gene through isogenic diagnosis, and the sex of the fetus should be determined through prenatal diagnosis to decide whether the pregnancy needs to be terminated or not, and even a chorionic villus biopsy is feasible to make a diagnosis of hemophilia.
