The amniocentesis result report form describes that: 400-500 bands of G chromosomes were analyzed by amniotic fluid cell culture, and trisomy 18, 13 and 21 were not found in the split analyzed. Here is a look at the data on the amniocentesis result report form. Analysis of the results: The absence of trisomy 18, 13 and 21 means that the chromosomes are normal, which means that the baby is developing normally. Abnormal amniocentesis results Amniocentesis is a test used to confirm whether the baby has a chromosomal disorder. If the amniocentesis result is abnormal, what will happen? What should I do? Simply put, amniocentesis is a test used to determine whether a baby has a chromosomal disorder. An abnormal amniocentesis result means that there is an abnormal amniocentesis result in a pregnant woman. There is no way to treat chromosomal disorders completely, so when there is an abnormal amniocentesis result, the doctor will advise the pregnant mother to induce labor, rather than blindly replacing the baby, after all, giving birth to a baby with a congenital disorder is not something that families will be happy to accept later. Are amniocentesis results accurate? The accuracy of amniocentesis results is one of the things that pregnant women consider before having an amniocentesis. In general, the success rate of amniocentesis tests for chromosomes in amniotic fluid cells is higher than 99%. A few of these amniotic fluid tests have no way for the cells to grow because the mother’s blood is so contaminated. Also because of other factors, the chromosomes of the cells may not be obtained. At this point, the amniotic fluid may have to be re-drawn. The correctness of the chromosomal results is up to 99.8% or more. In a few cases, there is a very small percentage of errors due to contamination of maternal blood cells with abnormal chromosomal characteristics. If the amniocentesis result shows a normal result, does it necessarily mean that the fetus is normal? Generally speaking, amniocentesis is a chromosomal test and a normal result only means that there is no chromosomal problem. It does not exclude other non-chromosomal disorders such as most congenital heart diseases, mental retardation, cleft lip and palate, and genetic disorders. In other words, even if the chromosomal test results are normal, about 2% of babies are still found to have some abnormality at birth. Therefore, the accuracy rate of amniocentesis results is quite high. How long does it take to get the results of an amniocentesis? The amniocentesis procedure is very short, so can I get the results right away? It is responsible to tell you that the results of amniocentesis are not available immediately. You can receive a phone call about a week after the puncture and we will tell you the quick results. The results of the chromosome analysis will be available only after about two to three weeks after the amniocentesis. The chromosomal analysis of amniotic fluid cells is not like a normal test where the results are available as soon as the amniotic fluid is put into the machine. The amniotic fluid chromosome analysis takes the cells that are extracted and must be cultured before they divide into sufficient numbers, a process that usually takes about five to ten days. After that, the chromosomes have to go through a process of harvesting, staining, observation, analysis, and review, so it takes this n a long time. Therefore, pregnant women should go home to recuperate from the amniocentesis without undue worry and go to the hospital after the results come out. Amniocentesis results can tell the sex of the fetus, but the general amniocentesis report does not include gender identification. The data in the amniocentesis report is mainly about chromosomal conditions, diseases caused by variations in the number, shape, structure and binding of chromosomes during pregnancy due to harmful chemicals, X-ray exposure, environmental factors, advanced pregnancy, inbreeding, etc. For example, chromosomal abnormalities can be detected in Down syndrome (trisomy 21), trisomy 18, trisomy 13, trisomy 8, trisomy 22, congenital testicular hypoplasia syndrome, XXY syndrome, Turner syndrome, trisomy X and poly X syndrome. The general test report will only show the number and structure of chromosomal abnormalities, but will not clearly indicate the sex of the fetus. However, according to the current law in mainland China, the report will not indicate the sex of the male and female, so our report result is written as 46, XN, which means the sex of the fetus is hidden. Unless there is an abnormality in the chromosome of the fetus, such as 47,XXY, etc., it will be indicated. Regardless of whether the fetus is male or female, health is the greatest asset that can bring happiness to you and your family.
