Our prenatal paternity test uses a non-invasive method for determining the true biological father of an unborn baby. The test is performed by collecting and analysing DNA obtained from foetal DNA obtained via a simple blood sample from the expectant mother after 10 weeks’ gestation. We then compare this to a DNA sample taken from the alleged father.

The kit contains two swabs for one alleged father. If you would like to test two alleged fathers at the same time, there will be an additional cost and we will provide additional swabs for the second alleged father.

The sampling process is non-invasive which means the test completely safe and risk-free to the unborn baby.

From around 10 weeks of pregnancy, the mother’s blood usually contains enough foetal DNA to establish a match with the alleged father. It is possible to obtain a DNA profile earlier in gestation (after 7 weeks) but this can be unreliable and require a repeat test closer to 10 weeks gestation.

The test will cost £859 inc. VAT for results in 10 working days from sample receipt at our laboratory.

If you would like us to arrange the sample collection for you by using a designated courier service, then fees apply for this service and are entirely dependent on the location. We generally find that the phlebotomist appointment will be between £80-110 and covers the return of the sample to our laboratory.

If you are arranging your own sample collection appointment, then you will be responsible for any fees from the phlebotomist. You will also be responsible for contacting the laboratory to arrange the courier collection or DHL drop point of the samples back to the laboratory for processing. Further information can be found in the FAQ – How do I return my samples to the laboratory?

Ways to pay:

• 50% deposit at the time of ordering with the remaining 50% due before report release
• If eligible, you may be able to set up a 3-4 month payment plan through Klarna or Clearpay – please call us to discuss

The Prenatal Paternity Test has a margin of error of less than 1%. The final probability of paternity will never reach the value of 100%, for both statistical and genetic reasons.

Although the risk of error of the test is low, it cannot be excluded. The paternity result can be confirmed in the postnatal phase using a standard Paternity DNA Test.

The mother will provide a non-invasive blood sample, and the alleged father will donate buccal (cheek) cell samples using two mouth swabs.

We would prefer if the mother and alleged father attended the same appointment for their sample collections, this helps us to reduce costs. However, it is not necessary for them to be together at sampling if this is a problem. Please contact us to discuss this. The sampling kit contains the blood collection kit for the mother and the alleged father’s buccal swabs.

You can either:

1. Ask us to arrange an at-home sample collection appointment – an appointment fee in the region of £90-120 will apply depending on your location.
2. You can arrange your own blood and mouth swab collection appointment with a trained phlebotomist. In this case, you will be responsible for any fees they have for this and for returning the samples to the laboratory in a timely manner to avoid deterioration of the samples. We will provide you instructions for returning the samples to the laboratory.

You may call our friendly team on <a href=”tel:0203 603 1189″>0203 603 1189</a> or email us at “mailto:sales@thatdnacompany.com” so we can discuss the next steps with you.

Or send us a message and one of our expert customer care advisors will contact you directly to discuss your testing needs with you.

You will be responsible for contacting the laboratory to arrange the courier collection or DHL drop point of the samples back to the laboratory. After blood draw, the samples must be shipped no later than the next day.

Samples which arrive at the laboratory more than five days after the sample collection date will be rejected and fees for a new sampling kit and any additional appointments will be applicable.

Results will be available within 10 working days of all case samples being received at our laboratory. The day we receive your completed case is Day 0.

We will keep you updated every step of the way. Secure results via a downloadable .pdf Test Report will be sent to the test participants by e-mail.

A hard copy of the Test Report can be posted for an extra £10 per posted report. Any further copies of the report such as by e-mail may be chargeable.

Once the results of the test have been issued to the test participants, we can then discuss the results with any of the test participants over the age of 16. Please expect that we may ask for evidence of identification before any discussions about the test.

The genetic profile of the child is inherited half from the mother and half from the father. Therefore, the genetic characteristics of the child which are not present in the mother are inherited from the father.

If the alleged father shows these characteristics, he is the biological father (COMPATABILITY), otherwise he is excluded as the biological father (NON-COMPATABILITY).

At the end of the process, a Test Report is issued, which indicates whether or not the man who carried out the test is the biological father.

If the result is deemed inconclusive, then we offer to repeat the test on one occasion.

Aside from the replacement kit or any sampling fees, this will be free of charge.

The most likely explanation for this will be that there was not enough foetal DNA in the mother’s blood stream for us to conduct the assay.  Generally, this is because the sample has been taken too early in the pregnancy.  We realise that it is not always easy to predict the “10 weeks” and generally, a repeat sampling a few weeks later will solve this problem.

If on the second attempt the assay still fails and we are sure the sampling has been at or after the 10 week cut off, then we will be providing additional advice.
