Question

Amniocentesis is a process to:

• A. Determine the sex of the fetus
• B. Determine any disease of heart
• C. Know about the disease of brain
• D. To grow cell on culture medium

Answer 1

The Correct Option is A

Amniocentesis is a prenatal diagnostic procedure where a small amount of amniotic fluid surrounding the fetus is extracted for testing. Here's a breakdown of why the best answer is "Determine the sex of the fetus" and further details:

Purpose of Amniocentesis:

• Genetic Testing: The primary purpose is to detect chromosomal abnormalities, genetic disorders, and neural tube defects in the developing fetus. This includes conditions like Down syndrome (Trisomy 21), cystic fibrosis, spina bifida, and other genetic diseases.
• Fetal Lung Maturity: In late pregnancy, it can be used to assess if the fetal lungs are mature enough for delivery.
• Sex Determination: Since the fetal cells contain chromosomes, including sex chromosomes, amniocentesis can determine the sex of the fetus. However, it's important to note that in many places, using amniocentesis *solely* for sex determination is discouraged or prohibited due to ethical considerations and potential misuse.
• Infection Detection: Amniotic fluid can also be tested for infection.

Why the other options are less accurate:

• "Determine any disease of heart" and "Know about the disease of brain": Amniocentesis is not a direct test for *all* heart or brain diseases. While some genetic disorders detectable through amniocentesis *can* have associated heart or brain defects, the procedure isn't specifically designed for those organs. Fetal ultrasounds and other specialized tests are better suited for assessing those organs directly.
• "To grow cell on culture medium": While amniotic fluid cells *are* often grown in a culture medium to increase the number of cells available for analysis (karyotyping, for example), this is a *step* within the overall process of amniocentesis, not the *primary purpose* of the procedure itself. The growing of cells on culture medium allows for further testing and analysis of those cells.

Therefore, the most accurate answer is: Determine the sex of the fetus. Although primarily used for detecting genetic and chromosomal abnormalities, amniocentesis also reveals the sex of the fetus.

Answer 2

Amniocentesis is a medical procedure primarily used to:

Determine the sex of the fetus
However, it is important to note that amniocentesis is more commonly performed for other diagnostic purposes, such as detecting genetic abnormalities, chromosomal disorders, and certain birth defects. The determination of fetal sex is just one of the many outcomes that can be derived from this procedure.
