    Amniotic fluid contains acetyl cholinesterase enzyme. What is the diagnosis ?

    • Open spina bifida

    • Gastrochisis

    • Omphalocele

    • Osteogenesis imperfecta

    Correct Answer
    A. Open spina bifida
    Explanation
    The presence of acetyl cholinesterase enzyme in the amniotic fluid suggests a diagnosis of open spina bifida. Open spina bifida is a neural tube defect where the spinal column does not close completely during fetal development. The enzyme acetyl cholinesterase is found in high levels in the spinal cord, and its presence in the amniotic fluid indicates a leakage of spinal fluid, which is characteristic of open spina bifida.
