Question

Which of the following tests cannot be examined by amniocentesis procedure?
A. Chromosome analysis
B. Detecting genetic defects
C. Maturity of fetal lungs
D. None of these

Answer 1

Hint:
Before answering the question, we should know about the amniocentesis procedure.
A pregnancy test is called amniocentesis. An ultrasound wand (transducer) is used during amniocentesis to display a baby's location in the uterus on a monitor. Then, a sample of amniotic fluid is obtained for analysis. This fluid contains fetal cells and substances made by the developing fetus. Your baby's amniotic sac is punctured with a needle, and a little sample of amniotic fluid is drawn out for testing. Although the entire consultation may last up to 30 minutes, the exam itself typically lasts around 10 minutes. Instead of being painful, amniocentesis is typically described as uncomfortable.

Complete answer:
Amniocentesis cannot identify structural birth problems such as cleft lip or palate or heart anomalies. On the frequently performed second-trimester ultrasound for every woman, many structural problems can be detected. Prenatal genetic tests are the most frequent diagnostic reasons to acquire amniotic fluid.
So, all of these tests can be examined by amniocentesis procedure.

Option ‘D’ is correct

Note:
An examination of the chromosomes in a sample of cells is known as chromosomal analysis. It can assist in determining whether an illness or disease is caused by genetic anomalies. The test can count the number of chromosomes and check for chromosome structural abnormalities. In a test termed CVS, a little portion of the placenta known as the chorionic villus is taken and analyzed to look for chromosomal or genetic problems in the unborn child.
