Nitrazine test (5% FP rate, 1% FN rate) - pH swab turns blue, indicating alkalotic amniotic fluid (pH 6.5 - 7.Some lubricants can affect FFN and amniotic fluid pH strip.Swabs for nitrazine, fetal fibronectin (FFN), GBS culture should also precede digital exam.Start with ultrasound to assess position of cervix and rule out placenta previa.Do NOT perform digital exam in patients who present with vaginal bleeding when >20 weeks pregnant due to potential for placenta previa.Type and Screen, CBC, Chem 10, Coags, U/A with culture, Utox (cocaine increases risk of abruption).New onset of vaginal mucus, blood, pink discharge, amniotic fluidÄifferential Diagnosis Vaginal Bleeding in Pregnancy (>20wks).Uterine contractions q 10 min (may be irregular).Can be triggered by infections, stress, hypertension, uncontrolled DM AmnioTest is a sterile swab impregnated with nitrazine yellow dye that when brought into contact with the upper vagina will absorb fluid and develops a colour to correlate with the pH of the absorbed fluid ranging from pH 5.0 to pH 7.5.Cerebral palsy, poor lung development, cognitive delay, etc The patient was considered clinically positive for ROM if either 1) amniotic fluid was seen leaking from the cervical os, or 2) if at least two of the following three clinical signs were present: visual pooling of fluid in the posterior vaginal fornix, positive nitrazine test, and/or microscopic evidence of ferning.Increased risks to child depending on age of fetus.Nitrazine (pH) testing, amniotic fluid crystallisation (fern testing). Defined as labor before 37 weeks (uterine contraction and cervical change) amniotic fluid and urine (which contains ammonia) because the polymer strip contains.This test is used to identify the presence of glucose and protein. A urine analysis should be performed on admission to labor and delivery. With a positive nitrazine test, the color of the strip changes to dark. Estimated gestational age based on physical exam. Study with Quizlet and memorize flashcards containing terms like 2 In many instances, a sterile speculum examination and a Nitrazine (pH) and fern test are performed to confirm that fluid seepage is indeed amniotic fluid. With the nitrazine test, some fluid from the vagina is placed on a PH sensitive strip.
