Common Questions

What happens if it is not possible to carry out a CVS?

It is not always possible to perform a CVS procedure (which is normally done between the 12th to 14th week) due to the position of the placenta, this affects approximately 5% of patients. If this is the case then the only option is to wait until 16 weeks gestation, which is the earliest an Amniocentesis procedure can be carried out or you can choose to use our non-invasive prenatal test. You will be charged for the professional scanning and consultation time instead of a full CVS. Lab fees still apply.

Is prenatal paternity testing for twins possible?

Yes. If you wish to carry out a CVS or Amnio during a twin pregnancy then additional fees will apply for the foetal sample collection laboratory process.

It is worth considering that the chances of having separate pregnancies from two different fathers are rare, however cannot be excluded. 

Confidentiality

All staff at DNA Worldwide, their Laboratory and the Foetal Clinic are bound by strict confidentiality. The results will only be provided to the nominated individuals requested. 

 

Common Questions (Continued)

What is the difference between amniocentesis and chronic villus sampling?

Whilst these two test are fundamentally similar, they are performed in different ways. Amniocentesis testing is performed 16 weeks after gestation and involves extracting a small amount of amniotic fluid from the sac surrounding the foetus. CVS testing is performed 10 weeks after gestation and involves removing a small sample of cells from the placenta.

What are the risks involved?

When performing a CVS prenatal paternity test, the risk of miscarriage is 1%, and when performing an Amniocentesis procedure, the risk of miscarriage of 0.5%.

What other prenatal tests are available?

Using the same genetic samples, we are able to offer a range of testing for various genetic disorders at the same time as your prenatal paternity test. (Additional lab fees apply).

For instance; you may have had a high risk result from your Down’s Syndrome screening or are simply seeking reassurance that all is well with your baby.
