Step 1 of 2

Amniotic fluid:

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

FLM (Fetal Lung Maturity) test:

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

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

• The specimen should be handled carefully and it must be delivered to the laboratory as quickly as possible

• The fluid for FLM test should be kept in ice for delivery to the laboratory and it should be refrigerated

Therefore, the specimen for FLM testing should be “transported on ice and refrigerated”. Hence, the correct answer is option.
