What is Amniocentesis?
Amniocentesis is a medically related procedure that includes removal of amniotic fluids from uterus for conducting antenatal test. Process involves collecting a sample of amniotic fluid for testing in a lab to determine genetic conditions involving fetal abnormalities. Amniocentesis accuracy is one main reason why it is so popular.
Why Amniocentesis Test?
Amniocentesis test is for following reasons:–
- In order to determine maturity of baby’s lungs at time of birth, amniotic fluid sample is tested
- Genetic testing involves amniotic fluid sample for determining conditions like Down syndrome
- Fetal infection – In very few occasions this testing is conducted to help in determining infections in fetus.
- Treatment is done to remove excessive amount of amniotic fluid from amniotic sac
- In order to determine baby’s gender
- In some cases, to determine baby’s health, where mother is suffering from blood sensitization
When is Amniocentesis Test Performed?
Amniocentesis test is conducted in second trimester between fifteen-week pregnancy and twenty-week pregnancy. Sometimes, it is also accomplished in third trimester. The following guidelines are essential before performing this test
- Drinking plenty of water is necessary as ultrasound is performed on a full bladder for correct results
- It is prudent to avoid usage of Aspirin pills five days prior to the procedure involving amniotic fluids
- It is necessary to avoid using Lovanox and heparin twenty four hours before test

Technique for Amniocentesis procedure includes following steps:-
- Cases where applicable transfusion looks like a risk it is better to give Rhesus immunoprophylaxis
- The procedure is accomplished under continuous ultrasound to determine the various positions of placenta, baby and amniotic-fluid pockets
- Belly of mother is now disinfected with antibacterial liquid to prevent infection
- A spinal needle of twenty two gauge is injected inside through walls of abdomen and uterus to amniotic fluids in amniotic sac
- Nearly ten to twenty ml of amniotic fluid is removed from amniotic sac
- Cell-filtration method is used
- Sample is now directed to a clinical lab
Risks Involved in Amniocentesis
Amniocentesis is not a process that involves pain as women barely feel discomfort at the time of injecting the needle. Still it is a risky venture and Amniocentesis risks encompass:-
- Bleeding in uterus
- Infection in uterus
- It is possible that any infectious disease can be transferred during this testing from mother to child
- Discomfort because of cramping in uterus
- Leakage of amniotic fluid can often lead to complications of orthopedic nature
- In case, baby decides on sudden movement at the time of inserting the needle and comes in its path, it can cause serious ramifications
- Instances are seen where baby’s blood cells enter mother’s bloodstream, causing complications
- Sometimes, a scar is visible on the baby’s body because of amnio test that was performed during pregnancy
- Risk of miscarriage is higher if executed before fifteenth week of pregnancy
Benefits of Amniocentesis
Amniocentesis benefits are as follows:-
- It gives correct results
- Tests helps to determine the existence of any chronic ailment
- Genetic defects are predetermined through amniocentesis tests
- Defects relating to neural tube is successfully determined through this tests
Cost of Undertaking an Amniocentesis Test
Amniocentesis Cost is between one thousand dollars to fifteen hundred dollars.
