Description
Why It’s Done
This test is usually recommended when there is a higher risk of chromosomal abnormalities, such as:
• Advanced maternal age (usually over 35 years)
• Abnormal results from prenatal screening tests (e.g., ultrasound or blood tests)
• Family history of genetic disorders or chromosomal abnormalities
• Previous pregnancy with chromosomal abnormalities
• Exposure to certain medications or infections during pregnancy
It helps parents and healthcare providers make informed decisions about pregnancy management.
Preparation for the Test
• Procedure: The test requires amniocentesis, where a needle is inserted through the mother’s abdomen into the uterus to withdraw amniotic fluid.
• Fasting: Not usually required.
• Medical Evaluation: A thorough ultrasound is done before the procedure to determine fetal position and amniotic fluid amount.
• Consent: Informed consent is necessary as the procedure carries some risks (e.g., miscarriage).
• Medications: Inform your healthcare provider about any medications, allergies, or health conditions.
• Rest: Avoid strenuous activity before and after the procedure as advised by your doctor.
