What does a positive ferning test mean?

What does a positive ferning test mean?

The proteins and saline content of amniotic fluid crystallize on a slide when dry yielding the appearance of ferns. A positive test shows the presence of fern-like patterns characteristic of amniotic fluid crystals.

What is ferning on microscopy?

The arborization pattern found when a drop of amniotic fluid is allowed to air dry on a microscope slide, known as ferning.

How do you assess ferning?

Examine the air-dried smear under the microscope without a coverslip and using low power magnification (10x magnification). I. Dried amniotic fluid produces a microscopically visible crystallization in a “fern” pattern. Dried normal vaginal fluid does not produce a “fern” pattern.

What does a negative fern test mean?

Negative: No crystallization seen (membranes are not ruptured) Positive: Crystallization seen (membranes are ruptured)

What is ferning in histopathology?

When high levels of estrogen are present, such as just before ovulation (or during pregnancy), the cervical mucus forms fern-like patterns due to crystallization of sodium chloride on mucus fibers. This pattern is known as arborization or ‘ferning’.

What is ferning cytology?

Vaginal cytology and cervical mucus “ferning” offer simple methods of assessing the prognosis in early pregnancy in cases of threatened or habitual abortion. A combination of the two methods increases the reliability of the prognosis.

Why does ferning occur?

What causes saliva ferning?

Estrogen rushes during the fertile phase of the cycle and this causes Sodium Chloride crystals to form in the shape of fern leaves in both saliva and cervical mucus. It is the crystallization of Sodium Chloride (NaCl) that produces the ferning appearance in saliva.

How are ferns transported?

Ferns are among the oldest plants on Earth with a vascular system, a network of vessels in their stems and leaves that transports water and minerals from the roots and sugars from the leaves and distributes them throughout the plant.

How long does ferning last on ovatel?

A. If the slide is kept in a dry environment, the fern pattern can stay for many months. If the slide is kept in a humid environment, the fern pattern can disappear rather quickly. I never see ferning when I use Ovatel. You are not using Ovatel correctly. You are not producing enough estrogen. I see ferning at random times during my cycle.

Can amniotic fluid have a ferning pattern?

False-positive results: “Ferning” is not specific for amniotic fluid. Other fluids (e.g., blood, cervical mucus, semen and some urine specimens) when dried can also yield microscopic crystallization in a “fern” pattern.

Why do I see ferns and dots while using ovatel?

Once your ovulation period is over, the ferns disappear and you will see dots. If you become pregnant, your body starts producing estrogen once again to support the growth of the fetus and you will see ferning while using Ovatel.

How do you use a cotton swab as a microscope?

Roll the cotton swab on a clean glass microscope slide. Allow slide to air dry completely before examination under microscope. A minimum of 10 minutes ispreferred as it increases the sensitivity for detection of “ferning”
