The Amniocentesis Procedure
Amniocentesis is typically performed in a hospital or specialised antenatal clinic, the amniocentesis procedure takes about 20 to 30 minutes. The actual fluid collection only takes a few minutes, but the entire process includes preparation, scanning, and recovery time.
Step-by-Step Overview:
- Ultrasound Guidance
Doctors use a detailed ultrasound to locate the position of the fetus, placenta, and a pocket of amniotic fluid. This ensures the needle avoids the baby and other sensitive areas. - Skin Preparation
A doctor cleans the abdomen with an antiseptic, and in some cases, uses a local anaesthetic to numb the area - Needle Insertion
A doctor carefully inserts a thin, long needle through the abdominal wall and into the uterus, withdrawing around 15–20 ml of amniotic fluid. - Monitoring
Doctors monitor the fetal heart rate and the mother’s condition during and after the procedure. - Lab Testing
The laboratory analyzes the fluid and examines fetal cells for chromosomal or genetic abnormalities. Results typically take 7 to 14 days, depending on the complexity of the tests.
Does It Hurt?
Most women report mild discomfort or cramping, similar to menstrual pain. Some feel only pressure during the fluid withdrawal.
What to Expect Afterwards
- Light cramping or spotting may occur.
- Most women return to normal activities the next day.
- Doctors will advise you to rest for 24 hours and avoid strenuous activity.
In rare cases, fluid leakage, infection, or uterine contractions may occur — your doctor will explain what to watch for and when to seek help.
