For preterm PROM, the biggest risk is a preterm delivery, which increases risks of complications for the baby. Tests for PROM involve analyzing vaginal secretions to determine if amniotic fluid is present. This test does not require a speculum examination.

The biggest risk of PROM is infection. The strips change color depending on the pH of the fluid.

Tests for Premature Rupture of Membranes

High levels of these substances mean that the membranes have broken. The strips will turn blue if the pH is greater than 6. This can lead to serious brain injuries and even death. A doctor will insert the speculum into the vagina and gently spread apart the vaginal walls.

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. Diagnosing Premature Rupture of Membranes If you suspect that your water has broken and there is fluid leaking from the vagina, your doctor will need to confirm that the membranes have actually ruptured.

Normal vaginal pH is between 4. A few drops of fluid will be placed on a microscope slide and observed under a microscope. Semen also has a higher pH, so recent vaginal intercourse can produce a false reading. If the fluid leaks out, the umbilical cord may get compressed between the baby and the uterus or in some cases, fall out of the uterus into the vagina.

If the membranes have ruptured, the colored fluid will be found in the vagina within 30 minutes. Once PROM is confirmed, your doctor will likely perform additional tests to assess the following: This allows the doctor to examine the inside of the vagina and to collect fluid directly from the vagina.

Therefore, if the membranes have ruptured, the pH of the sample of vaginal fluid will be higher than normal.

Your doctor will examine you and observe the fluid coming from the vagina. If your doctor decides to delay delivery, they should continue to monitor you and your baby to make sure that this decision remains the best course of action.

Injecting dye into the amniotic sac through the abdomen. Nitrazine Test This test involves putting a drop of fluid obtained from the vagina onto paper strips containing Nitrazine dye.

What Does a Positive Nitrazine Test Signify?

If the baby survives, they will often have long-term problems, including: These include prolactin, alpha-fetoprotein, glucose, and diamine oxidase. Tests that measure the levels of chemicals known to exist in the amniotic fluid but not in vaginal fluid. Amniotic fluid has a higher pH of 7.

It works by detecting the placental alpha microglobulin-1 biomarker in the amniotic fluid.Nitrazine paper is used as a screening test to detect small quantities of amniotic fluid in vaginal secretions.

It is used in conjunction with the Fern Test to help detect ruptured membranes. Nitrazine paper offers more sensitivity than litmus paper.

15'. A nitrazine test performed during pregnancy measures the pH of vaginal fluid to determine whether the membranes have ruptured, although a positive test is not conclusive. The pH level could be affected by blood in the mucous or bacterial vaginosis, for example, rather than amniotic fluid caused by.

Sonkir pH Test Strips, Test pH Level for Acidic Alkaline Universal Litmus Test Paper Strips Instant Results in Seconds, Full pH Range of (1-Pack pH Test Strips). In pregnant women, premature rupture of membranes (PROM) occurs when the amniotic sac that surrounds the baby (the membrane) breaks before the start of labor.

Nitrazine or phenaphthazine is a pH indicator dye often used in sensitive than litmus, nitrazine indicates pH in the range of to Nitrazine is usually used as the disodium salt.
