A blue color on Nitrazine testing and ferning indicate the presence of amniotic fluid. Therefore, if the membranes have . Pages 23 This preview shows page 7 - 10 out of 23 pages. Reported accuracies are 84 to 100% for the ferning test and 87 to 97% for the nitrazine test. Amniotic fluid has a higher pH of 7.1 to 7.3. The Quick Check fFN test() for detection of the fetal fibronectin in the vaginal fluid is a simple bedside test, more sensitive, and specific than Ferning and Nitrazine tests, it can be used as complimentary test to confirm the clinical diagnosis of premature rupture of fetal membranes. Part I: Of 112 samples allowed to dry on a slide for 3 minutes only, 86.6% were ferning positive . 5, 6 On the other hand, false negative results can be obtained when the amount of fluid available for analysis is scant. Abstract. Reported accuracies are 84 to 100% for the ferning test and 87 to 97% for the nitrazine test. 4. School Rutgers University; Course Title NURSING MISC; Uploaded By GrandPenguinPerson461. Sterile speculum exams, nitrazine, and ferning. Blood-tinged amniotic fluid . . What is ferning what is nitrazine the fern test often. The ferning and nitrazine tests of amniotic fluid between 12 and 41 weeks gestation. Reported accuracies are 84 to 100% for the ferning test and 87 to 97% for the nitrazine test. 6. This pattern is known as arborization or 'ferning'. Smits F, et al. Another method to detect the rupture of the membranes is by doing the nitrazine test. So, if you find the vaginal fluid to have higher pH, then it means that there is a premature rupture. Author Patricia R McCartney 1 Affiliation 1 School of Nursing, The State . This combination monoclonal and polyclonal immunoassay test that detects PP12 and AFP has an efficacy comparable to conventional testing and better than the individual components of conventional testing (ferning, nitrazine), is a quick and easy-to-use test that can be performed by a wider variety of Duration of membrane rupture for greater than 24 hours negatively affected the accuracy of all three tests. Fern test has also 13-30% false negative and 5-30% false positive results . 3. Part I: Of 112 samples allowed to dry on a slide for 3 minutes only, 86.6% were ferning positive . If nitrazine and ferning were positive, but Amnisure is negative, we would consider the patient positive for ROM. Our study was designed to determine if these tests are applicable throughout gestation. Observation of a fern pattern indicates the presence of amniotic . Nitrazine test may also lead to false positive or negative results due to probable contamination by alkaline urine, semen, blood, meconium, vaginitis, cervicitis and using antibiotics. Samples were obtained from amniocenteses between 14 and 42 weeks. This test involves testing the pH of a sample of vaginal fluid.
