- At a CVS or amniocentesis (refer to Abbreviationfinder.org) you examine your fetus for chromosome diseases and for certain hereditary diseases
- Placenta praevia sample can be taken when you are between 10 and 16 weeks pregnant during your pregnancy, while villus sample will only be taken from you are 16 weeks pregnant during pregnancy
Why do you get created CVS/amniocentesis?
If the nuchal translucency scan and double test has shown an increased risk that the fetus has Down syndrome (trisomy 21), Pataus syndrome (Trisomy 13) or Edwards syndrome (Trisomy 18), you get offered a CVS/amniocentesis.
You can also get offered the survey if you have previously been pregnant or have given birth to a child with a chromosome disorder, if there are hereditary diseases in your family or child faderens, or if the ultrasound scan has found signs of anomalies in the your fetus.
Placenta praevia sample can be taken when you are between 10 and 16 weeks pregnant during your pregnancy, while villus sample will only be taken from you are 16 weeks pregnant during pregnancy.
How is the survey?
It’s a doctor, which is carrying out the investigation, along with an Assistant, often called a sonograf. You may like to have an adult accompanying with the examination. You may like to have a little urine in your bladder when you meet to study.
You will have taken the test through your abdomen. First you will be washed with disinfectant liquid, after which the doctor or sonografen scanner you on the abdomen to measure the fetal size and to determine where the sample will be taken.
The actual sample is taken with a thin needle, at the same time you will be scanned. The whole procedure takes only a few minutes.
It is different from person to person how to labels sampling. Most experiencing only a minor discomfort.
You must be in the Department for at least 15 minutes after sampling. You must take it easy the rest of the day.
It is common to feel discomfort in the hours after the test in terms of menstrual like pain and heaviness sensation in the lower abdomen. The pain usually disappears within the first 24 hours.
If you start to bleed, the amniotic fluid leaking, or you get prolonged pain, you must contact the on-call physician or your family doctor.
Within a week you will, if everything is normal, either receive a letter or a phone call with the responses to the survey of the most common chromosome defects, including down syndrome. You can also get the child’s gender, if you want it.
The final answer will usually only receive within about 3 weeks because it takes longer to examine all the chromosomes.
If the answer to the sample is not normal, you will be called up by http://Abbreviationfinder.org.
