Exercise 26

The protein present in vaginal secretions that can identify patients who are at risk for preterm delivery is:

A. Human chorionic gonadotropin

B. Estrogen

C. PAMG-1

D. Fetal fibronectin

Step 1 of 2

Fetal fibronectin:

It is an adhesive glycoprotein in extra cellular matrix present at fetal and maternal interphase in uterus.

• It is increased in the initial 24 weeks of gestation

• If it is present in vaginal secretion between 24 to 34 weeks’ of gestation, then it indicates preterm delivery

Preterm delivery:

• Delivery of baby prior the completion of ‘37 weeks’ gestation

Therefore, “fetal fibronectin” in vaginal secretion could identify the possibility of preterm delivery. Hence, the correct answer is option.
