Your child can be screened to work on the occasion of Down Syndrome.
Screening Tests for Down Syndrome are not Mandatory
Screening tests for Down syndrome are offered to women during the first or second quarter, but they are not mandatory and not all women have chosen them.
Therefore, it is important before thinking about the possible outcomes before you do a screening test and what you can do about them. You can discuss this with your doctor or midwife.
If your age or family history increases the chance of having a child with this problem, you may want to consider amiensentis or chorionic vimus sampling instead of screening tests.
Down syndrome is a disorder that the child is pregnant. It arises when the child has an extra chromosome (chromosome 21). It is not known why this happens.
Affected children may have intellectual disability and physical problems, degree of problems is different, some people require a lot of help with daily activities and some living almost independently. Some will need medical treatment for physical problems.
About 20 people in 20 women (9 5%) will receive a report saying that their child is not at increased risk.
Screening Tests for Down Syndrome
Maternal screening can not give you a definitive answer to “my child’s down syndrome” question, but it will show if your unborn baby is likely to be normal (down syndrome).
A report about more than 20 women (9 5%) of screening tests will be available, which states that their child is not more at risk of having Down syndrome. About 1 out of 20 (5%) will get a report that is a risky risk.
There are currently two options for down syndrome screening.
First Quarter Screening
First quarter screening includes:
Blood test performed between 10 weeks and 13 weeks and 6 days
Ultrasound (which is called ‘Nichole transorcinisation’ – is looking at the back of your child’s neck) is done between 11 weeks and 13 weeks and 6 days.
To perform this ultrasound test you will usually need a referral from your family doctor in private radiology practice.
The results of each of these tests are mixed to meet your risk of taking an affected child.
Second Quarter Screening
This screening test can be done between 14 weeks and 20 weeks and 6 days.
This is a blood test from which your risk can be calculated. This blood sample can also be tested to check whether your child may get a better chance of having neural tube defects.
What Can Test Say?
A report that is not ‘at increased risk’ means that your child has only one very rare chance in down syndrome, it does not guarantee a perfect baby, but due to increased risk due to almost all pregnancies Down syndrome will not happen.
If there is a risk of developing after the first trimester screening, then 95% of these children will not have Down syndrome.
After the second quarter screening, 98% of babies who are on ‘increased risk’ will not have Down syndrome only further tests will show what is the problem of infants.
Depending on the results, you may need to decide whether to conduct further tests or not. Here are the more tests:
Chorionic Villus Sampling (CVS)
There are some risks of CVS and aminocentis – your doctor or midwife will be able to discuss with you. These tests are very accurate.
You do not need to test it – it’s your choice to discuss this with your doctor or a trained counselor.
How Reliable are the Tests?
If pregnant during 10 and 13 weeks, blood tests and ultrasound scans will detect about 90% of children affected by syndrome simultaneously.
If blood tests are done between 15 and 20 weeks, then it will identify approximately 75% of children with Down syndrome.
What Happens if Your Child is Diagnosed with Down Syndrome?
If your child is diagnosed with Down syndrome, then you will be given this information that it can affect your child and the rest of your pregnancy as well as the support services available.
Then you have to decide whether to continue your pregnancy or to end it soon.
