5mLs of maternal blood will also be collected to exclude maternal contamination in the amniotic fluid sample. The cytogenetic laboratory Path West) will issue a separate account for the chromosomal testing.

The full fetal chromosome result will take 10 days on average to complete. In general, a preliminary chromosome result (QF PCR or FISH) is available in 24-36 hours. It is not appropriate to have your children attend for an amniocentesis procedure and we would request you arrange childcare when scheduling for this procedure.

We strongly suggest you have someone attend your amniocentesis appointment with you and have them drive you home. Vaginal bleeding or fluid loss following an amniocentesis is uncommon and requires prompt medical attention. It is common to feel some uterine cramps or discomfort following an amniocentesis. The presence of uterine fibroids (benign tumours of the uterine muscle) or prior vaginal bleeding may increase the pregnancy loss rate following an amniocentesis.įetal injury following an amniocentesis is rare. Are there any risks to having an Amniocentesis?Īn amniocentesis is an invasive diagnostic procedure and does carry with it a small but definite pregnancy loss rate (less than 0.5%). These two pictures demonstrate a normal chromosome result for a boy (left) and girl (right). In a normal fetus there are 46 chromosomes in each cell of the body (22 pairs of autosomes and 2 sex determining chromosomes). The full fetal chromosome result will take 10-14 days on average. In general, a preliminary chromosome result is available in 24- 36 hours. Women who are Rhesus negative will need to have an injection of anti-D following the amniocentesis (which will be administered by the medical staff at Women’s Imaging Services immediately following the amniocentesis). In general only a single needle insertion is required.ĭocumentation of the maternal blood group is required at the time of the amniocentesis. The needle is within the amniotic sac for about 30-60 seconds. A 10 cc syringe is attached to the amniocentesis needle once it is correctly positioned within the amniotic sac and about 15 mls of amniotic fluid is aspirated.

The ultrasound transducer rests on the maternal skin at all times to ensure the needle enters the amniotic sac at the safest location so as to avoid contact with the fetus. We do not routinely administer local anaesthetic for amniocentesis procedures.

Following the application of povidone iodine to sterilise the maternal skin, a 22 gauge needle is inserted through the abdominal wall. How is an amniocentesis performed?Īn amniocentesis is performed with the use of continuous ultrasound guidance to facilitate accurate placement of the needle into the amniotic sac without interaction with the fetus.Ī preliminary ultrasound examination is conducted to assess the pregnancy and pelvic structures.

potential cytomegalovirus or toxoplasmosis infection). In certain circumstances an amniocentesis may be indicated to assess a pregnancy at risk for congenital infection (eg. increased probability at the screening First Trimester Screen, high probability following NIPT, previous affected pregnancies, parental chromosome problem). Why would an amniocentesis be performed?Īn amniocentesis is performed to assess the fetal chromosomes in pregnancies with an increased likelihood for chromosome problems (eg. Amniocentesis, cannot be safely performed in the first trimester and is typically conducted at 16 weeks gestation. The fetus sheds cells from the skin and urinary tract which then enter the amniotic sac and can be obtained from the amniotic fluid by amniocentesis. An amniocentesis is a prenatal diagnostic test in which a small volume of amniotic fluid (typically about 15mls) is removed from the sac around the fetus to enable the testing of the fetal chromosomes, DNA or infection studies.
