A 28 weeks pregnant multigravida with preeclampsia presented with fulminant signs. Urgent C-section was planned. Best method for the diagnosis of lung maturity is:

L/S ratio in amniotic fluid

Phosphtidyl glycerol estimation in amniotic fluid

Bilirubin in amniotic fluid

Amniotic fluid creatinine

Question Category:

Gynaecology & Obstetrics

Correct Answer:

Phosphtidyl glycerol estimation in amniotic fluid

Description:

Phosphatidylglycerol (PG) is a minor constituent of surfactant. It begins to increase appreciably in amniotic fluid several weeks after the rise in lecithin. Its presence is more indicative of fetal lung maturity because PG enhances the spread of phospholipids on the alveoli. Ref: Mehta S.H., Sokol R.J. (2007). Chapter 13.
