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.
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 []: 2021-04-10 · Amniotic fluid is the substance which surrounds the fetus as it grows in the uterus.

The above two tests have shown the best results with a sensitivity of 90% . Amniotic fluid was obtained from 38 patients between 16-38 weeks' gestational age who underwent amniocentesis.
Characteristic arborization, or typical ferning pattern, confirms amniotic fluid and spontaneous membrane rupture.

Clinical inquiry: Ferning in amniotic fluid: is it a useful indicator of ruptured membranes? Gaddey H(1), Bailey J, Smith RF. Author information: (1)David Grant Family Medicine Residency, Travis Air Force Base, CA, USA. 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 to 97% for the nitrazine test. Amniotic fluid ferning in early gestation. Borten M, Friedman EA. Ferning of amniotic fluid was studied in early pregnancy. Arborization was demonstrated during the interval of 6 1/2 to 16 weeks by flame-drying.

Amniotic fluid was obtained from 38 patients between 16-38 weeks' gestational age who underwent amniocentesis. 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 slides were examined microscopically for the presence of ferning.

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.
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?
