Preterm premature rupture of membranes (PPROM) refers to rupture of fetal membranes prior to labor in pregnancies of less than 37 weeks. It occurs in 3 percent of pregnancies and is responsible for one-third of preterm births. A history of PPROM, genital tract infection, antepartum bleeding, and cigarette smoking are risk factors for PPROM.
In addition, the prevalence of a positive Amnisure test™ was not increased with cervical effacement or dilatation in patients with labor and intact membranes (Groups 2 and 3; p>). This finding suggests that a positive Amnisure test™ may be associated with labor itself, rather than increased gestational age or cervical eazye.info by:

Fern test refers to detection of a characteristic 'fern like' pattern of cervical mucus when a specimen of cervical mucus is allowed to dry on a glass slide and is viewed under a low-power microscope. The fern test is used to provide evidence of the presence of amniotic fluid and is used in obstetrics to detect the rupture of membranes and the onset of labor.
