Exercise 27

Describe the specimen-handling and processing procedures for testing amniotic fluid for bilirubin, fetal lung maturity (FLM), and cytogenetic analysis.

Step 1 of 4

Amniotic fluid:

Fetus is surrounded by a membranous sac called amnion. The existence of fluid can be seen in amnion.

Collection of fluid:

Sterile syringes are used to gather fluid with the volume of 30 mL.

• The first 2 or 3 mL (milliliter) of amniotic fluid is discarded, because it is contaminated by maternal blood, cells, and tissue fluid
