Question

In context of amniocentesis, which of the following statements is incorrect?

• A. It is used for prenatal sex-determination
• B. It can be used for detection of Down syndrome
• C. It can be used for detection of cleft palate
• D. It is usually done when a woman is between 14-16 weeks pregnant

Answer 1

The correct option is C It can be used for detection of cleft palate

Cleft palate is a developmental abnormality (an opening or split in the roof of the mouth) which may occur in the developing foetus and so it can be detected by sonography, not by amniocentesis.

Amniocentesis is a foetal sex-determination and disorder test based on the chromosomal pattern in the amniotic fluid like in case of Down syndrome. It is usually done when a woman is between 14-16 weeks pregnant.
