What causes PROM isn’t known for sure. Most women who experience it don’t have any risk factors. Some of the possible causes include: Having an earlier pregnancy affected by a genetic condition. A health care provider might suggest amniocentesis to look for that condition. Don’t use tampons, take a bath, or have sex. Your amniotic sac has kept your baby protected in a sterile environment. Now that it has ruptured, you need to protect your baby from infection.

The risk of amniocentesis causing complications is higher if it's carried out before the 15th week of pregnancy, which is why the test is only done after this point. Caramore T, Dresang LT.What is the best way to diagnose rupture of membranes? Evid Based Pract. 2011;14(6):5. Unless the baby’s lungs are fully mature, the health care provider will want to wait to induce labor. You will talk about your own situation and the risks and treatment options available to you and your baby. Leaking amniotic fluid. Rarely, amniotic fluid leaks through the vagina after amniocentesis. In most cases, the amount of fluid lost is small and stops within one week with no effect on the pregnancy.

Genetic testing. Genetic amniocentesis involves taking a sample of amniotic fluid and testing the DNA from the cells for diagnosis of certain conditions, such as Down syndrome. This might follow another screening test that showed a high risk of the condition.

Diagnosis of fetal infection. Occasionally, amniocentesis is used to look for infection or other illness in the baby. 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. In a case-control prospective study, Marcellin et al (2011) compared the performance of2 rapid tests for the diagnosis of PROM based on the detection of IGFBP-1 and PAMG-1 in cervico-vaginal secretions. Pregnant women between 24 and 41(6/7) weeks' of gestation, consulting for profuse amniotic fluid loss (group 1) or for other reasons without any rupture of membrane (group 2) were included in the study. Successively, AmniSure test (PAMG-1) without speculum, and then Actim Prom test (IGFBP-1) during speculum examination were performed during the same visit. A total of 80subjects (40 in each group) were included between 25(1/7) to 41(1/7) weeks of gestation. AmniSure diagnostic test demonstrated a sensitivity and specificity of 95 % (82.4 to 99.4) and 94.8 % (79.3 to 98), respectively and a PPVand NPVof 95 % (84.7 to 100) and 94.8 % (87.9 to 100), respectively. Actim Prom test demonstrated a sensitivity and specificity of 97.5 % (85.7 to 100) and 97.4 % (82.4 to 99.4), respectively and aPPV and NPV of 97.5 % (88.5 to 100) and 97.4 % (92.5 to 100), respectively. The authors concluded that both tests have similar performance to diagnose PROM. The first results of the test should be available within 3 working days and will tell you whether Down's syndrome, Edwards' syndrome or Patau's syndrome has been discovered.With the help of the amniotic fluid examination, it is also possible to determine the risk of Down syndrome or trisomy 21. The AChE protein is an enzyme of the nervous system. If a neural tube defect is present in the unborn baby, the AChE level is also significantly elevated.

Having positive results from a prenatal screening test. If the results of a screening test — such as the first-trimester screen or prenatal cell-free DNA screening — show high risk or are worrisome, amniocentesis might confirm or rule out a diagnosis. A playpen can be very practical in everyday life! Which model is suitable for your needs, you can read in my guide. Simhan HN, Canavan TP. Preterm premature rupture of membranes: Diagnosis, evaluation and management strategies. BJOG. 2005;112 Suppl 1:32-37.

Needle injury. During amniocentesis, the baby might move an arm or leg into the path of the needle. Serious needle injuries are rare.
