[10] Basic fluid, like amniotic fluid, will turn the nitrazine paper from orange to dark blue. [9] Fern test: A sterile cotton swab is used to collect fluid from the vagina and place it on a microscope slide.
The amniotic fluid is the protective liquid contained by the amniotic sac of a gravid amniote. This fluid serves as a cushion for the growing fetus, but also serves to facilitate the exchange of nutrients, water, and biochemical products between mother and fetus. For humans, the amniotic fluid is commonly called water or waters (Latin liquor ...

The amniotic sac consists of two parts: The outer membrane is the chorion. It is closest to the mother and physically supports the much thinner amnion. The chorion is the last and outermost of the membranes that make up the amniotic sac. [13] The inner membrane is the amnion. It is in direct contact with the amniotic fluid, which surrounds the ...
Amniotic fluid is composed of fetal cells, urine, and lung secretions. [46] 18-20 mL of amniotic fluid is slowly aspirated, with the first 1-2 mL typically discarded due to higher risk of maternal cell contamination. [2] The remaining sample is submitted for laboratory testing. [1]
Placental alpha microglobulin-1 (PAMG-1) is a human protein that was first isolated in 1975 from amniotic fluid.PAMG-1 is an important biomarker for the detection of premature rupture of fetal membrane (PROM) The high concentration of PAMG-1 in amniotic fluid means it can be used to detect if this fluid is present in the cervico-vaginal discharge of pregnant women; the presence of PAMG-1 in ...
She now knows that the strange symptoms were actually her amniotic fluid leaking and her cervix dilating prematurely. Zurawski was diagnosed with an incompetent cervix.
