Expecting a baby and want to clear any paternity doubts? Who’ztheDaddy?™ offers a 100% safe and risk free prenatal paternity test. All you need to undergo is a harmless and quick medical blood draw to complete our test. Using blood samples from the expectant mother and mouth swabs from alleged father, we can confirm the paternity of the foetus with an accuracy of 99.9%.

Science behind the test

Our prenatal test is medically speaking “non invasive” and “non surgical”. Other testing methods during pregnancy such as amniocentesis or chorionic villus sampling are risky, “invasive” surgical procedures and are not recommended as means of establishing the paternity of an unborn child. 1 in 200 cases of amniocentesis result in miscarriage. These invasive tests are only recommended when doctors suspect some abnormality in the unborn baby. With our non invasive prenatal paternity test we can guarantee no side effects or miscarriages, ensuring the absolute safety of the mother and the unborn child.

The test can be done if you are in your 9th week from conception (this means you will be in your 11th week of pregnancy, starting from the first day of your last menstrual period). You may use our pregnancy calculator to work out your dates.

When your samples reach the laboratory, we proceed to separate the foetal DNA in the mother’s blood from the maternal DNA. We isolate 2,688 single nucleotide polymorphisms from the blood sample of the mother.

The only time we cannot conduct the test is if the Mother is expecting twins or if the alleged Fathers are close blood relatives.

Sample Collection

Kits are prepared especially for this test and contain the ideal sterile, vacutainer, blood collection tubes needed to hold the blood samples from the mother. These special tubes also contain an anticoagulant which will ensure the blood does not clot/congeal and preserve the DNA inside it. Ensure blood samples are collected by a qualified person.

You will also find 4 swabs which are to be used for collecting the samples of the alleged father. The swabs need to be rubbed under the tongue and against the inner cheek in order to collect the DNA sample required.

It just takes 3 simple steps

  • Order your kit
  • Fix your appointment for the blood draw*
  • Send us back your samples

 

*You may ask any doctor to collect your blood samples or find a person who specializes in collecting blood samples (a certified phlebotomy technician).

You do not need any specialist to assist you with our prenatal test and you do not need to undergo any unpleasant procedures with unpleasant side effects. Diagnostic techniques such as amniocentesis and CVS are both done under local anesthetic and following these procedures, the expectant mother may experience pre-mature labor, miscarriage, fever, soreness and a range of other side effects or complications.

FAQs

How much is the test?

Our prenatal test is offered at £899 – this includes testing the expectant mother and the alleged father. If the second alleged father is available for the test, we always suggest including his sample. There is a small fee for testing the second alleged father.

When will the results be ready?

Results will be sent by email in just 7-10 working days. We do not offer an express service on this test.

When can I do the test?

The test can be carried out at 9 weeks from conception (this means you will be in your 11th week of pregnancy, starting from the first day of your last menstrual period).

What happens if I take the test too early?

Carrying out the test too early means a high chance of inconclusive results. In such cases we do not find enough foetal DNA in the blood sample. Every pregnancy is different and there are very rare cases where the amount of foetal DNA is below the levels required by the laboratories despite the blood extraction taking place at 9 weeks from conception (this means you will be in your 11th week of pregnancy, starting from the first day of your last menstrual period). This is something we have no control over but in such cases we will offer our client the chance to re-send fresh blood samples which will be tested at no added cost.
