Wiped hydropuncture is a test performed during pregnancy to determine certain genetic abnormalities, congenital anomalies, and other disorders of the fetus. The test is typically performed between 15 and 20 months of pregnancy.
Samples are evaluated when amniocentesis occurs of amniotic fluid . Amniotic fluid Amniotic fluid is a colorless or dull yellow fluid that surrounds and protects the fetus during pregnancy. The fluid It contains cells that provide important information about the fetal well.
Amniocentesis is considered a diagnostic test. It is meant to indicate whether the baby has certain health problems, and the results are almost always accurate. Diagnostic tests are distinct from prenatal screening tests for genetic disorders. Prenatal screening tests pose no risk to you or your baby, but they do not make a diagnosis. They only indicate whether your baby probably has a health problem. If the tests indicate that your baby may have a problem, the caregiver can recommend amniocentesis or another diagnostic test to find out the most likely one.
Other names: amniotic fluid analysis
Why is it used?
Amniocentesis is used to determine specific health problems in the fetus. We are usually familiar with the following
- Genetic and chromosomal disorders, in any quantity:
- Down syndrome, a condition that causes mental disorders and other health problems
- Cystic fibrosis, mucus and sweat disease causing thick, sticky mucus that can lead to respiratory and digestive problems
- Sickle cell disease, a group of red blood cells that can cause anemia and other health problems.
- Tay-Sach disease, a disease that degrades nerve cells, causing psychological and physiological problems, often resulting in death in childhood (rare).
Tests can still be used.
- If there is a chance of a very early family (premature birth), check the baby’s formation. In this case, amniocentesis this test is done in the second half of the pregnancy.
- Diagnose infections or other diseases of the baby
Why do I need amniocentesis ?
Having amniocentesis Is it your choice? This test may be necessary if the baby is at high risk for health problems. You may be at increased risk for the following
- You are 35 years of age or older. （Your risk of having a baby with a genetic disorder increases with age.)
- You have had a prenatal screening test that indicates your baby has the condition.
- You or your partner have a family situation with a genetic disorder or neural tube defect.
- You or your partner have undergone genetic testing indicating that you are a carrier of a genetic disorder.
- You or your partner have a baby with a genetic disorder or birth defect.
Amniocentesis is not for everyone. Before you decide to let the test what you have experienced and what you have in the test.
What happens during amniocentesis ?
Testing is usually done between 15 and 20 months of pregnancy. Sometimes testing is done during pregnancy to find out if the baby is not obvious or to diagnose certain infections or diseases such as fetal anemia caused by RH compatibility.
During the procedure:
- You lie flat on your back on the examination table.
- Your doctor may use a discouraging medication on your stomach.
- The physician will move the device using the ultrasound tube, SO-Calcled Transducer, over the stomach. The ultrasound uses sound waves to show the baby and placenta so your doctor can see where to take the sample. of amniotic fluid .
- Your doctor places the sensitive needle in your stomach and moves away slightly. of amniotic fluid .
- When the sample is removed, the physician will determine the baby’s heartbeat with the help of ultrasound.
The procedure usually takes about 15 minutes. After that, you can be told not to do any heavy exercise or physiological exertion for the next 24 hours.
Do I need to prepare for the test?
If you are at the beginning of pregnancy, you may need to leave urine prior to the test to ensure that you have an absolute pee. This helps to ensure that the uterus is in the best position for the test. In advanced pregnancies, the test explicitly requires an empty bladder.
Was there any danger in the test?
During the test, you may feel slight crushing, pressure, and/or cramping. You may then experience slight discomfort, vaginal loss of blood, or a small amount of blood loss. of amniotic fluid This comes from the vagina.
The potential for serious complications is very small. Amniocentesis has a fairly small risk (less than 1%) for causing a miscarriage.
What do the results mean?
Amniotic fluid You can test for a number of different disorders. The results of your study depend on the study performed by your midwife or gynecologist.
- Normal results are reported as “normal” or “negative”. This means that the baby is almost ruled out of the condition being tested for, but it does not mean that the baby does not have any health problems.
- Results that are not considered normal are reported as “abnormal” or “positive. This means that the baby most likely has the condition being tested for.
Your midwife will explain your test results. The amniotic fluid fluid is fairly accurate, but in some cases your midwife or gynecologist can order more tests to check your baby.
It helps to speak with a genetic consultant before testing and/or after receiving your results. Genetic consultants are trained professionals in genetics and genetic testing who can help you make sense of your results.
Is there anything else I should know? amniocentesis ?
In some cases, information about the fetus is needed 15-20 months before the test is done. amniocentesis Usually, it is a done deal. In that case, you can look again at a diagnostic test called ChorionVilli (CVS). A small monster tissue sample of the placenta is taken during this study.
The CFS test can be performed between 10 and 13 months of gestation, allowing more time to decide what to do if the results are abnormal. As. amniocentesis CFS is a real diagnostic test that can detect certain genetic disorders. However, the chance of miscarriage is slightly greater.
When testing, know that a prenatal genetic diagnostic test is different from a screening test. In a screening test, the fetus may have certain problems. It is possible to take another screening test while the baby is actually healthy. However, if the screening analysis indicates that the baby is at risk for a particular issue, you amniocentesis or a summary that recognizes the probability.
