Nitrazine swab. Nitrazin — Википедија 2022-12-29
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.
