Positive fern test with amniotic fluid as seen under the microscope. The fern test is a medical laboratory test used in obstetrics and gynecology.The name refers to the detection of a characteristic "fern like" pattern of vaginal secretions when a specimen is allowed to dry on a glass slide and is viewed under a low-power microscope.
Positive fern test with amniotic fluid as seen under the microscope: Specialty: Obstetrics: Symptoms: Painless gush or a steady leakage of fluid from the vagina [1] Complications: Baby: Premature birth, cord compression, infection [2] [1] Mother: Placental abruption, postpartum endometritis [2] Types: Term, preterm [2] Risk factors
Nitrazine paper test; Fern test; Amniotic fluid index; For results to be roughly 90% accurate in infection detection, a combination of both an arborization test and nitrazine paper test may be used. [11] An arborization test assesses the patient's vaginal secretions, while a nitrazone paper test uses the nitrazine paper to examines vaginal pH.
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 ...
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 chance of survival at 22 weeks is about 6%, while at 23 weeks it is 26%, 24 weeks 55% and 25 weeks about 72% as of 2016. [189] With extensive treatment up to 30% of those who survive birth at 22 weeks survive longer term as of 2019. [190] The chances of survival without long-term difficulties is less. [24]
3. To check the color of the fluid. If there is a suspicion of the presence of meconium (the contents of the baby's bowel), certain preparations must be made. Suctioning must be set up and more personnel are required to be in attendance. 4. To avoid having the baby aspirate the contents of the amniotic sac at the moment of birth.
Leaking or rupture of membranes: Leaking or rupture of membranes may be caused by a gush of fluid or a slow constant trickle of fluid. This is due to a tear in the membrane. Premature rupture of membranes can also result in low amniotic fluid levels. Placental problems: Placental problems may cause low amniotic fluid. If the placenta is not ...
