Exercise 12

The presence of phosphatidyl glycerol in amniotic fluid fetal lung maturity tests must be confirmed when:

A. Hemolytic disease of the newborn is present

B. The mother has maternal diabetes

C. Amniotic fluid is contaminated by hemoglobin

D. Neural tube disorder is suspected

Step 1 of 2

Phosphatidyl Glycerol:

Phosphatidyl Glycerol (PG) is another lung-surface lipid that is essential for adequate lung maturity.

• It is detected in amniotic fluid after the gestation period of 35 weeks.

• Lecithin production is parallel to the production of PG, but during maternal diabetes the production of PG is delayed

• Maternal diabetes of the mother indicates the presence of PG in amniotic fluid during fetal lung maturity test

Therefore, presence of PG in amniotic fluid during fetal maturity tests is confirmed during “maternal diabetes of the mother”. Hence, the correct answer is option.
