Part III: 17 samples were tested for ferning and nitrazine at 1 hour, and again at 1 week. Sixty-six samples were tested within 1 week and again at 2 weeks. All samples remained ferning and nitrazine positive. Therefore optimal analysis of suspected amniotic fluid occurs when specimens are air-dried for 10 minutes. Leaking amniotic fluid might feel like a gush of warm fluid or a slow trickle from the vagina. It will usually be clear and odorless but may sometimes contain traces of blood or mucus. Gross contamination of amniotic fluid with blood or antiseptic solutions may decrease the diagnostic accuracy of ferning, whereas contamination with meconium doesn't (SOR: C, bench research).

+ + + 1986-03-01 · Feming of amniotic fluid was studied in early pregnancy. Arborization was demonstrated during the interval of 6 1 2 to 16 weeks by flame-drying. Air-drying yielded a spectrum of crystallization from none prior to 8 weeks to full ferning by 16 weeks. Technical differences are stressed. The ferning and nitrazine tests of amniotic fluid between 12 and 41 weeks gestation. Most studies investigating the usefulness of ferning and nitrazine methods for detecting the presence of amniotic fluid following ruptured amniotic membranes have employed samples from vaginal pooling. Reported accuracies are 84 to 100% for the ferning test and 87 However, it is much less sensitive and specific for women with fluid loss who aren't in labor (SOR: B, 1 prospective cohort study).

Pooling of fluid in the vagina or leakage of fluid from the cervix, ferning of the dried show absence of or very low amounts of amniotic fluid in the uterine cavity. The diagnosis of rupture of the membranes by traditional methods of nitrazine paper determination and fern crystallization has been reported to be 93-98%  (A) Typical ferning pattern of dried amniotic fluid (400).

At ovulation the cervix secretes a very clear mucus that is receptive to sperm cells but also acts as a filter to weed out bacteria and unhealthy sperm cells 1990-05-01 · The ferning test for detection of amniotic fluid contamination in umbilical blood samples Andrew Chao, MD, James P. Herd, MD, and Khalil M. A. Tabsh, MD Los Angeles, California There is currently no standard means of detecting amniotic fluid contamination in fetal blood obtained by percutaneous umbilical blood sampling. • From 20 weeks up to term (mainly fetal urine) • At 18th week, the fetus voids 7-14ml/day; at term fetal kidneys secretes 600-700ml of urine/day into AF. - Fetal respiratory tract secretes 250ml/day into AF. - Fluid transfers across the placenta. - Fetal oro-nasal secretions. ferning — n.

During much of pregnancy, AF is derived almost entirely from the fetus and has a number of functions that are essential for normal growth and development []: It helps to protect the fetus from trauma to the maternal abdomen It cushions the umbilical cord from compression between the 2012-07-07 However, it is much less sensitive and specific for women with fluid loss who aren't in labor (SOR: B, 1 prospective cohort study).

Amniotic fluid was immediately mixed with freshly obtained, heparinized fetal cord blood in varying concentrations (blood to amniotic fluid 1:5, 1:10, 1:20).

• The normal range is wide but the approximate volumes are: - 500 ml at 18 weeks - 800 ml at 34 weeks. - 600 ml at term. No ferning of the vaginal fluid is detected, and you reassure your patient that her membranes have not ruptured. You explain that the laboratory technicians will use which five basic techniques (in order) to manipulate, grow, examine, and characterize any microorganisms present in the collected specimens? Ferning in amniotic fluid: Is it a useful indicator of ruptured membranes?

The Fern Test, often used in conjunction with the Amnio Test or Nitrazine pH paper test, detects leakage of amniotic fluid from the membranes surrounding the fetus during pregnancy.

What is the pH of amniotic fluid? Amniotic fluid was obtained from 38 patients between 16-38 weeks' gestational age who underwent amniocentesis.
