Chromosome Analysis of Amniotic Fluid, also known as amniocentesis for karyotyping, is a prenatal diagnostic test that examines the chromosomes in a fetus’s cells. The procedure involves collecting a small amount of amniotic fluid, which surrounds the fetus in the uterus, to analyze the fetal DNA for chromosomal abnormalities.
The test evaluates the number and structure of chromosomes to detect conditions such as:
• Down syndrome (Trisomy 21)
• Edwards syndrome (Trisomy 18)
• Patau syndrome (Trisomy 13)
• Turner syndrome (Monosomy X)
• Other chromosomal deletions, duplications, or rearrangements
Results typically take 7–14 days, as the fetal cells in the fluid must be cultured before analysis.

    Description

    Why It’s Done:

    This test is usually recommended during the second trimester (15–20 weeks of pregnancy) when:
    • The mother is 35 years or older, increasing the risk of chromosomal abnormalities.
    • Results from other screening tests or ultrasounds suggest possible fetal abnormalities.
    • There is a family history of genetic disorders.
    • Parents are known carriers of chromosomal translocations or abnormalities.
    • Previous pregnancy was affected by a chromosomal condition.
    It helps expecting parents make informed decisions about their pregnancy based on accurate genetic information.

    Preparation:

    • Timing: Typically performed between 15 and 20 weeks of gestation.
    • Bladder: You may be advised to empty your bladder before the procedure to reduce the risk of complications.
    • Consent: You’ll be asked to sign an informed consent form after discussing the risks and benefits with your doctor.
    • No fasting is required before the procedure.
