About this deal
Your health care provider or a genetic counselor will help you understand your amniocentesis results. With CVS, the risk of miscarriage is similar to the risk of miscarriage for amniocentesis (up to 1 out of every 200). Rupture of membranes was diagnosed definitively on review of the medical records after delivery. The investigators stated that the cause of fals- positive results in 3 patients was unknown, and that the possibility of small leak that sealed over could not be excluded.

These studies indicated that the AmniSure is a promising method of detection of PPROM. However, controlled clinical studies are needed to determine the clinical effectiveness of the AmniSure ROM test over standard diagnostic methods for ROM. When you’re pregnant, you may feel like everything leaks: Your bladder becomes fuller faster, and you may leak urine. Your vaginal tissues also may produce extra fluid to help your baby pass more easily. So it can be difficult to determine if fluid is urine, amniotic fluid, or vaginal fluid.
Risks
You may choose to continue with your pregnancy, while gathering information about the condition so you're fully prepared. This test involves testing the pH of a sample of vaginal fluid. Normal vaginal pH is between 4.5 and 6.0. Amniotic fluid has a higher pH of 7.1 to 7.3. Therefore, if the membranes have ruptured, the pH of the sample of vaginal fluid will be higher than normal. Fetal lung testing. If delivery is planned sooner than 39 weeks, amniotic fluid might be tested to help find out whether a baby's lungs are mature enough for birth. This is rarely done.

For genetic amniocentesis, test results can rule out or diagnose some genetic conditions, such as Down syndrome. Amniocentesis can't identify all genetic conditions and birth defects.About 30 percent of preterm births are due to PPROM. It occurs in about 3 percent of all pregnancies in the United States.
