It works by detecting the placental alpha microglobulin-1 biomarker in the amniotic fluid. This test does not require a speculum examination.
Newer noninvasive tests such as the AmniSure ROM test from QIAGEN Sciences. 
High levels of these substances mean that the membranes have broken. 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. If the membranes have ruptured, the colored fluid will be found in the vagina within 30 minutes. Dye test: Injecting dye into the amniotic sac through the abdomen. A few drops of fluid will be placed on a microscope slide and observed under a microscope. If your water is broken, the fluid mixed together with estrogen will create a “fern-like” pattern under a microscope due to salt crystallization. Semen also has a higher pH, so recent vaginal intercourse can produce a false reading. If blood gets in the sample or if there is an infection present, the pH of the vaginal fluid may be higher than normal. This test, however, can produce false positives. A blue strip means it’s more likely the membranes have ruptured. The strips will turn blue if the pH is greater than 6.0. The strips change color depending on the pH of the fluid. This test involves putting a drop of fluid obtained from the vagina onto paper strips containing Nitrazine dye. Therefore, if the membranes have ruptured, the pH of the sample of vaginal fluid will be higher than normal. Amniotic fluid has a higher pH of 7.1 to 7.3. Normal vaginal pH is between 4.5 and 6.0. This test involves testing the pH of a sample of vaginal fluid. This allows them to examine the inside of the vagina and to collect fluid directly from the vagina. They will insert the speculum into the vagina and gently spread apart the vaginal walls. Your health care provider will collect some fluid from the vagina using a medical tool called a speculum in order to do most of these tests. 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. Tests for PROM involve analyzing vaginal secretions to determine if amniotic fluid is present. They will then order tests to help confirm PROM or PPROM. Your health care provider will examine you and observe the fluid coming from the vagina. 
If you suspect that your water has broken and there is fluid leaking from the vagina, your health care provider will need to confirm that the membranes have actually ruptured. At the hospital, simple tests can confirm that your membranes have ruptured. Women who deliver within 24 hours after their water breaks are less likely to get an infection, so it’s important to go to the hospital as soon as possible after the membranes rupture. Your health care provider may choose to induce your labor early due to the risk of infection to your baby. If your pregnancy is less than 37 weeks and your membranes rupture, your health care provider will have to decide whether to deliver your baby immediately or to try to continue the pregnancy.If your pregnancy is past 37 weeks and your membranes rupture, your baby is ready to be born.The earlier your membranes rupture, the more serious it is for you and your baby. It occurs more frequently in twin pregnancies. PPROM occurs in about 3 percent of pregnancies and causes about one-third of preterm births, according to American Family Physician. It is more commonly referred to as “when your water breaks.” Membrane rupture that occurs before the 37th week of a pregnancy is called preterm PROM (PPROM). 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.
