A nitrazine swab is a diagnostic tool used in obstetrics to determine the pH of cervical mucus. This test can be useful in determining whether a woman is in labor or not, as well as helping to predict the likelihood of preterm labor.
The pH of cervical mucus can change throughout a woman's menstrual cycle, and it is typically more acidic during the non-fertile parts of the cycle and more alkaline during ovulation. As a woman approaches labor, the pH of her cervical mucus becomes more alkaline, which can be an indicator that labor is imminent.
To use a nitrazine swab, a healthcare provider will collect a sample of cervical mucus by gently inserting the swab into the cervix. The swab is then placed in a solution that changes color depending on the pH of the mucus. A healthcare provider will then compare the color of the solution to a chart to determine the pH of the mucus.
There are some limitations to using nitrazine swabs as a diagnostic tool. For example, the pH of cervical mucus can be affected by a number of factors, including infections, medications, and vaginal douching. In addition, nitrazine swabs are not always accurate and may produce false positive or false negative results.
Despite these limitations, nitrazine swabs can be a useful tool in helping healthcare providers to predict the likelihood of preterm labor and to determine whether a woman is in labor. They can also be used to monitor the progress of labor and to determine whether labor is progressing normally.
In conclusion, nitrazine swabs are a diagnostic tool used in obstetrics to determine the pH of cervical mucus. While they have some limitations, they can be useful in predicting the likelihood of preterm labor and in determining whether a woman is in labor.

Then she passed her meconium also. Thankfully I was over 37 weeks and he came out just fine, but with borderline jaundice which made him sleepy for feeds. This test, however, can produce false positives. Amniotic fluid has a higher pH of 7.

Talk to your health care provider if you take steroid medications.
Near Term 34 to 36 weeks Your health care provider will likely proceed to deliver the baby if the hospital has neonatal care available. Since the fluids might be contaminated with blood or other secretions, these tests look for substances or certain characteristics that are normally only found in amniotic fluid. I am the 2nd person I know to have this issue with the swabs. Completed a nitrazine swab checks for ph level and nothing showed and assured me nothing was wrong. These include prolactin, alpha-fetoprotein, glucose, and diamine oxidase. TLDR: Waters leaked for a few days because OB relied only on nitrazine swabs to check PH level. If the membranes have ruptured, the colored fluid will be found in the vagina within 30 minutes.
A Group Leader is a What to Expect community member who has been selected by our staff to help maintain a positive, supportive tone within a group. Ask for 2nd opinion and further tests be performed. The biggest risk of PROM is infection. PPROM occurs in about 3 percent of pregnancies and causes about one-third of preterm births, according to The earlier your membranes rupture, the more serious it is for you and your baby. For preterm PROM, the biggest risk is a preterm delivery, which increases risks of complications for the baby. Therefore, if the membranes have ruptured, the pH of the sample of vaginal fluid will be higher than normal. Look at it and smell it.
