Paternity Testing

Uncertainty can put a lot of pressure on relationships. Paternity testing clarifies who is the biological father of your child. It will remove all doubts and provide you with a solid foundation for the way forward both before or after the baby is born.

Description

The prenatal (during pregnancy) paternity test offered at the FGIH uses Next Generation Sequencing (NGS) technology to analyse the baby’s DNA which is free floating in the mother’s blood from the placenta.

Taking blood from the mother and swabs from the possible father carries no risk of miscarriage and previous pregnancies or miscarriages will not affect the result.

A consent form, blood tubes, swabs and all the required packaging for the safe return of the samples is included in the sampling kit. The kit, the taking of the samples and all postage and packaging required to return it back to the Forensic Genomics Innovation Hub is included in the price.

Previously a paternity test during pregnancy required the collection of a specimen using needles through an amniocentesis or a chorionic villus sample. This is no longer necessary, and you do not need a GP or specialist gynaecologist involved.

Our phlebotomy group will visit you at a location of your choice. The samples are then returned to the laboratory where results will be available 7 working days later. Reports are confidentially released to both parties tested. This test can be performed from 10 weeks of pregnancy.

If the possible father tested is the biological father the result will say it is > 99.9% more likely that he is the father, rather than not. If the result is less than this and the genetic markers do not match the baby the result will mean that the man is NOT the biological father of the baby. There are no other possible results.

Available Soon – Paternity Test after the child is born (PT)

  • Includes three swabs, one for the mother, one for the possible father and one for the child
  • Confidential results in 7 working days
  • Testing performed in a UK Forensic laboratory using highly sensitive and accurate technology
  • Confidential counselling upon request

Description

This test is performed after a child is born.

A cheek swab from both parents and the child need to be analysed. The swabs and the return postage back to the Forensic Genomics Innovation Hub is all included in the kit you are ordering. Also a content form for both parents is included in the kit. Upon receipt at the FGIH the DNA will be extracted from all 3 swabs and a genetic fingerprint will be analysed and compared.

If the probability that the tested father is the biological father the result will say it is > 99.9% more likely that he is the father, rather than not. If the result is less than this and the genetic markers do not match the baby the result will be a paternity exclusion. There are no other possible results.

FAQ

  1. Contact FGIH on 023 8011 8981/2 or email us at info@fgih.co.uk to discuss your situation and stage of pregnancy in total confidence.
  2. If you do not need to talk to us and are sure that you are at least 10 weeks pregnant then please order your test above.
  3. A test kit (uniquely identified and assigned to you) will be automatically issued upon receipt of payment to FGIH. If unable to pay through the website please contact us.
  4. Our phlebotomists will contact you to organise your apt.
  5. Mother and suspected father attend appointment together – you will need a legal original current ID document. These include: Driving license, passport, valid visa/right to remain permit

The pricing will be announced as soon as the method is fully validated & accredited. But the price will include:

  1. the sample collection kit
  2. the collection of the samples by a registered phlebotomist at an address of your choice from the pregnant mother (note that her samples contains the baby’s DNA) and the alleged father.
  3. Your results will be provided in a written report issued within 7 working days
  4. strictly confidential counselling
  1. The test will take between 5 and 7 working days from receipt at the FGIH laboratory. FGIH will contact you to let you know that the samples have arrived safely at the lab and are fit for processing (i.e. no tampering of the returned test kit).
  2. An email will be sent out advising the report is ready. Results will only be emailed to the address provided on the request/consent form at the time of sampling.

Should results be required quicker than 7 working days from receipt of samples in the lab, an additional £200 will be charged for a 4 working day final report.

Advances in genetic testing have resulted in the ability to identify the biological father of a foetus in the fairly early stages of pregnancy. This allows for accurate foetal DNA paternity testing from a simple blood draw from the mother with no risk of miscarriage. During pregnancy the placenta releases foetal DNA into the mother’s blood.  Unlike most DNA, which is found inside a cell’s nucleus, these fragments are free in the circulation and called cell-free DNA (cfDNA). There needs to be sufficient foetal DNA in the mother’s circulation for the test to work (usually by 10 weeks of pregnancy). These fragments are isolated and compared with the mother and the alleged father’s DNA profiles. A swab of the cells lining the inside of the mouth is all that is required from the alleged father. This more advanced technology also enables us to look at many more markers across the human genome than the standard paternity offered after birth.

  1. DNA profiles generated at the Forensic Genomics Innovation Hub are among the most informative available. In contrast to the standard paternity test available looking at between 24 and 27 markers across the human genome our test will provide information across 152 markers. The resulting statistics that are obtained are extremely conclusive. 
  2. Results of parentage tests indicate that an individual can either not be excluded as being the biological father of the child (that is, the profiles match where expected), or that an individual can be excluded as being the biological father of the child (that is, the profiles mismatch in specific regions). Resulting statistics will be over 99.99% for a match report and 0% for an exclusion report. There will be nothing in-between.

The FGIH will provide at least 99% probability of paternity in the case of a match or 0% probability in an exclusion. It is however important to note that due to certain scientific limitations a guaranteed result cannot be provided. It is important to be aware of this. It may be that the mother’s blood simply doesn’t contain enough foetal DNA for the test to detect it and obtain a DNA profile of the foetus. The risk of this outcome is higher if the test is conducted too early in pregnancy. Hence the strong recommendation to only test after at least 10 weeks of pregnancy. In a very small number of cases (3-5%) foetal DNA never reaches a sufficient level for a successful test. This can be for a number of medical reasons beyond the laboratory’s control. 

Please note, if you decide to cancel the test before we have completed the test, we cannot refund you based on the high cost of the test to the laboratory.

  1. For the NIPPT testing a 10ml blood sample is taken from the pregnant mother by a qualified phlebotomist. Her blood contains both her DNA and foetal DNA. 
  2. A swab is taken from the suspected father, the mother and the child in case of the PT-testing as the DNA in the blood and the cells in the mouth are the same, and equally as accurate. For the NIPPT testing a swab with DNA from the suspected father is mandatory. Please note that there is no foetal DNA however in the swab from the mother. Foetal DNA is only free floating in the mother’s blood supply.

No. The laboratory will not use this kind of sample for this test, also any other material without consent of the alleged father will be rejected by FGIH. Anyone being DNA profiled for paternity testing at FGIH must be in attendance and sign a consent form. A hair sample (or similar samples) collected in advance does not adhere to chain of custody requirements as people must be sampled in front of the visiting phlebotomist (who is also a witness to the test).

Whilst we fully understand that this is an emotional time in order to ensure that the medico-legal requirements are met, both parties are to be tested in the same space at the same time.

  1. The mother and the alleged father will both receive a copy of the report. If a carer/patient representative is in attendance and signs the consent form they too may be entitled to a report. This test does NOT require the input of your GP or a medical practitioner, or a Solicitor. It is a purely confidential test between the FGIH, the mother and the alleged father.
  2. Results will be issued by email only to the email provided on the consent form.

Please do not hesitate to contact us on 023 8011 8981 or email lab@fgih.co.uk for a strictly confidential explanation of the report. Please have the report to hand as you will be asked to share the unique test report number with us so we can take you through it. Explanations/ counselling are free of charge and a priority to us.

In summary you will receive one of two different reports. Either it will say the alleged father “CANNOT BE EXCLUDED” with a matching probability of 99.99% or it will say the alleged father is “EXCLUDED” as the biological father with a matching probability of 0%.

Just follow the order form above.

A saliva sample will be provided by the mother, the alleged father and the child on a swab. Then the DNA of these samples will be extracted and the genetic fingerprints will be analysed and compared. 

Your results will then be sent to you and include the following saying. Either it will say the alleged father “CANNOT BE EXCLUDED” with a matching probability of 99.99% or it will say the alleged father is “EXCLUDED” as the biological father with a matching probability of 0%.
