DNA Testing

in Dna

The concern that we may have regarding our parentage or suspicions of parenthood has at some time or another been in the mind of those who have been subject to either claims or involvement.

Of course the technology used in the past to either eliminate or confirm was based on blood typing, and serological testing that at best provided a likelihood of compatibility or confirm no such link if there was an incompatible result.

Certainly these tests were not effective for identification and determining relationships.

Those days are gone! With the introduction of successful DNA testing in the late 1970s and 1980s, scientists saw the powerful tool this process was for identification and determination of biological relationships. Thanks to the advent of DNA testing, we can now determine the identity of individuals and their relatives with exceptional accuracy and conclusiveness.

DNA testing is a powerful tool for identification. With today's technology, DNA tests can now identify individuals with almost 100% certainty. The issue of course is that if you are concerned about the result, testing in publicly or Government accessed DNA testing facilities will almost certainly become public despite the privacy rules that may apply.

Fortunately there are facilities that will provide sound credentials for you to peruse, but a couple of key issues are;

ACCREDITATION: When dealing with such tests, make sure that the company you select is using a appropriatelyatel yaccredited laboratory. The highest level of international accreditation includes ISO17025 and AABB. A laboratory has to work very hard to achieve such accreditation and show the highest standards of technical competence and assurance of quality. Ensure your service provider works through a testing lab that is fully accredited.

TECHNICAL SUPPORT: Make sure that the company selected has the experience to offer you the best technical support throughout the entire testing process. In particular for test involving the general that they are backed by proper scientific support.

Each case is different and deserves undivided attention from the testing organisation by directing you to the best testing options and methods through what can be a very difficult time.

Genetic Testing

Families who need the results for court should choose a legal parenthood dtest process. However, a majority of families need to know the results for their own peace of mind because the results may show unwanted associations. Families split up, people are sent to jail and lives are ruined. However, in reality, dna tests have many constructive outcomes.

Genetic testing is an important and powerful technology that is impacting health care planning and decision making. To track and better understand this rapidly evolving technology doctors are now able to identify which medications to prescribe. Similarly, genetics can provide preventive information for patients;

Private vs Legal DNA Testing

Results obtained from samples which are collected in private are just as accurate as results from legal tests. However, because the samples are collected in private, they are intended for personal knowledge only and cannot be used in court.

Samples taken for legal paternity tests need to be taken according to accreditation standards. Be sure to follow instructions carefully. Samples for a Legal DNA Test must be collected or witnessed by a neutral third party and proper verification of identity documented for each person.


Paternity DNA tests are not expensive, but beware of tests that cost less than $100. There have been situations where people bought one of those tests advertised for under $100. After the test was done they were then told they needed to pay another several hundred dollars in order to receive their results.

How are Samples Collected

Buccal swab collections are the newest and most progressive method to collect DNA and buccal cell samples are furthermore easy for transport, storage and processing. To collect the buccal cell sample, four buccal swabs (similar to cotton tips) are brushed with moderate strength along the inner cheek. Buccal swabbing is straightforward and painless, and can be performed even in newborn babies. Chorionic villus sampling (10-13th week of pregnancy), and amniocentesis (14-24th week of pregnancy) samples contain DNA from the foetus, and can also be analysed.

Medical genetic testing can help many people make informed choices about their healthcare. The difference is between those with a family history of inherited diseases or other risk factors vs those who may or may not be at increased risk of widespread diseases due to a genetic variation with small effects. Medicare covers 85% of the cost.
