What is the result of amniocentesis?

Abstract: How long does amniocentesis take? Amniocentesis, also called amniocentesis, is one of the prenatal examination items. Information about fetal health and development can be obtained through amniocentesis, which is an important diagnostic means to help us understand whether the fetus has chromosome diseases. So how long will it take to get the results of amniocentesis? What is the result of amniocentesis? How long does amniocentesis take? How many days does amniocentesis take? How to treat the result of amniocentesis?

How long does amniocentesis take?

How soon will the results of amniocentesis come out? The results of amniocentesis usually come out in 2-3 weeks after operation, but when the results come out depends on the hospital's time schedule. Generally speaking, amniocentesis only takes 2-3 days to get the result of chromosome abnormality, because the chromosome analysis of cells is not like general examination. As long as the amniotic fluid is put into the machine, the results can be obtained quickly by direct fluorescence in situ hybridization of interphase cells. However, because the cells extracted by amniocentesis must be cultured to divide into enough numbers, this process usually takes about 7- 14 days. After that, the chromosomes have to go through the processes of dyeing, observing, taking photos, enlarging photos, cutting and pasting, and auditing, so it takes 2-3 weeks. Reminder: pregnant women go home to rest after amniocentesis, so don't worry too much. Generally, if the test result is positive, that is, the test result is abnormal, the doctor will inform you as soon as possible. Generally, you don't tell the situation, which means that the situation is normal, as long as you get the report card at the appointed time.

What is the result of amniocentesis?

1. Look at the report describing the results of amniocentesis. The description is as follows: After G banding analysis of 400-500 bands in amniotic fluid cell culture, 18, 13, 2 1 trisomy were not found in the analysis. Results Analysis: 18, 13, 2 1 trisomy were not found, which indicated that the chromosome was normal, that is, the baby developed normally.

2. Look at the data of AFP content on the amniocentesis report. This data can generally be used to see the risk of fetal malformation. Normal value: AFP in normal fetal amniotic fluid reached its peak at 13 weeks of pregnancy, with an average of 26.303 μ g/L (26,303 ng/mL); The decline of 19 weeks of pregnancy was the fastest, and the average value of full-term pregnancy was1.266 μ g/L (1266 ng/ml). The AFP of amniotic fluid is higher than the average value, indicating that the fetus is probably anencephaly or spina bifida, and it may also be a variety of other malformations, such as congenital nephropathy, esophageal or intestinal atresia, umbilical defect, cystic hydroma, sacrococcygeal teratoma, Rh blood group incompatibility, congenital stupidity, congenital gonadal hypoplasia and so on.

3. It can be seen that amniotic fluid estriol (E3) can accurately reflect the functional status of fetal placental unit, and can estimate the prognosis of abnormal fetus. Results Analysis: The E3 value of normal fetal amniotic fluid was greater than 100μg/ml. If the E3 value on the analysis sheet is less than 100μg/ml, it indicates that the fetal prognosis is poor.
