How long does it take for amniocentesis to produce results?

Amniocentesis is a necessary method of prenatal examination, mainly to check whether there are chromosomal diseases and symptoms of Down syndrome. This operation requires a thin needle to be inserted into the amniotic fluid to extract the amniotic fluid and check the condition of the amniotic fluid. In addition, the fetus needs to be cared for after the amniocentesis. Generally, the test results can be seen one week after the amniocentesis. Expectant mothers can understand the method of amniocentesis clearly.

How long does it take for amniocentesis to produce results?

Amniocentesis is one of the prenatal examination items. By extracting amniotic fluid samples from pregnant women, some information about the health and development of the fetus can be obtained. This examination has a history of several decades and has become a part of prenatal diagnosis. In my country, it is currently widely used. This method can detect problems with the fetus, and many expectant mothers have undergone this operation before delivery.

The results of amniocentesis are usually available 4 weeks later. If the test result is positive, the examiner will be notified immediately. Generally, if there is no notification, it means that the situation is normal. Don't be nervous, relax, do regular check-ups, pay attention to nutritional supplements, and your baby will be very healthy.

However, the specific results of amniocentesis still depend on the hospital's regulations. Each hospital has a different time for issuing results, usually around 3 to 4 weeks.

How to do amniocentesis

Amniocentesis is a method of prenatal diagnosis, which is generally suitable for prenatal diagnosis in mid-pregnancy. Amniotic fluid is in the amniotic cavity. The best time to do amniocentesis is between 16 and 24 weeks of pregnancy. At this time, the fetus is small and the amniotic fluid is relatively abundant. The fetus floats in the amniotic fluid and is surrounded by a wider amniotic fluid belt. This makes it less likely to injure the fetus during amniocentesis.

Before amniocentesis, an ultrasound should be performed to determine the fetal position and condition to avoid accidental injury to the fetus. After selecting the insertion point, disinfect the skin, spread a disinfectant towel, and perform local anesthesia. Then use a lumbar puncture needle with a needle core to vertically insert the needle into the selected place. There will be two empty sensations when the needle passes through the abdominal wall and uterine wall. Remove the needle core, use a 2ml syringe to aspirate 2ml of amniotic fluid, and then use a 20ml empty needle to aspirate 20ml of amniotic fluid.

After aspirating the amniotic fluid, remove the needle, cover with sterile gauze, and apply pressure for 2-3 minutes. At this time, the pregnant woman should rest in bed for 2 hours. After amniocentesis, be very careful when taking a shower and do not touch
