DNA Paternity Testing – 5 key questions you should ask your DNA testing provider.
from:
DNA paternity testing in its purest form is the application of DNA technology to provide information about the parentage of an individual (usually a child). The mother of the child is rarely disputed, and most of the time DNA testing is requested to inform the likely father of a child.
DNA is inherited from our parents, with half coming from the mother, and the other half from the father. This pattern of inheritance allows the opportunity where the mother of the child is not disputed, to produce a putative DNA profile of the biological father. The process is relatively simple in that the final DNA profile of the child is composed of a series of bands which can only come from the two parents. If the mother’s bands are deducted from the child profile the remainder must come from the biological father. Any male that may consider himself the father can have a DNA profile produced and compared against the remaining bands in the child’s profile.
There can only be two outcomes from this type of comparison. The first is a ‘no-match’ scenario where the remaining bands in the child’s profile could not have come from the sample obtained from the alleged father. This is known as exclusion and eliminates the possibility of this individual being the biological father of the child. The second is a ‘match’ scenario where the remaining bands in the child’s profile could all be accounted for by comparison with the alleged father. If this is the case the significance of the match needs to be assessed by a DNA interpretation expert who will provide a degree of certainty associated with the likelihood that the alleged male is the biological father of the child.
Before you commission any Paternity DNA testing you should be sure you have clear answers to the following 5 key questions:
1. Has the DNA testing facility been accredited by a validated external body such as the American Association of Blood Banks (AABB). If the answer is no, do not have your testing done by this company, you may not be able to rely on the results.
2. Does the company carrying out the DNA testing have a thorough track-record in this area of work, and have they proved their technology in court? Be wary of companies that sub-contract their testing. DNA profile interpretation can be a tricky business,
and there is a lot at stake when you commission a DNA test, and you want reassurance on the reliability of your service provider.
3. Is the company you are planning to use an accredited laboratory or merely a broker? Brokers are simply in this game to make money, and have no interest in the quality or the impact of this life changing technology. Avoid them irrespective of the tempting pricing they may offer you.
4. What degree of certainty does the company provide in relation to the results of the tests? An exclusion should be 100% with an inclusion at, at least 99.99% confidence levels. These are the figures that are expected in a court of law.
5. Does the internal quality standard require duplication of all results before they are reported to the customer? This is an industry standard requirement which is often overlooked by some of the ‘cheaper’ DNA testing providers.
If the answer to any of these questions is unclear, my strong advice is to find an alternative provider. You simply do not want to trust such an important piece of work to a company that does not guarantee a top quality product, with excellent customer care back-up.

Although prenatal DNA testing is a little more involved than a standard home DNA paternity test, the process is still fairly straightforward. The accuracy levels of prenatal DNA testing are identical to standard DNA paternity testing. Prenatal DNA testing requires samples from the unborn child, the mother, and the alleged father. DNA samples from the unborn child are collected via amniocentesis or CVS. Amniocentesis is the removal of a small sample of the amniotic fluid surrounding the fetus. Amniocentesis can be performed during the 14th to 24th week of pregnancy.
Prenatal DNA testing also requires a separate physician's fee for drawing the DNA samples. DNA samples from the parents are collected via a buccal swab rubbed against the inside of the mouth. As with standard DNA paternity testing, DNA sample collection procedures may vary depending on whether you need court-admissible results. Prenatal DNA testing for court proceedings requires proof of identities and chain of custody verification by a witness.
Questions have been raised regarding the ethics of prenatal DNA testing, given that there are risks to the fetus. But there are several instances in which prenatal DNA testing is preferred. For example, in cases of artificial insemination, there may be a need to verify the sample source.In cases of rape where there is also a consensual partner, prenatal DNA testing can determine the father of the unborn child. Determining parentage may also provide financial benefit to the mother during pregnancy. Some mothers desire prenatal DNA testing because it gives them time to plan ahead, and may reduce stress during an already very stressful time. )
