Genetic testing has entered popular consciousness with the emergence of detailed knowledge about the human genome. Whether it is deciding the paternity of a contested child, or looking out for early signs of hereditary disease, genetics are now at the leading edge of medical science, replacing more old fashioned methods like blood testing with a surprising efficiency. As is the case with any advance in science, it has affected the way people approach their health.
The Internet is flooded with offers of cheap DNA testing. These kits claim to offer a reliable paternity test that makes the process easy and painless, for under 100. At the chemists, a DNA testing kit can be bought for a period of less than half of this price. As DNA testing becomes more popular, many are tempted by these bargain rates.
The ease of access to the kits is a key element in their popularity. Paternity testing isn’t always about legal rights, but for the peace of mind of either or both parent: their proliferation is a reflection of how important this security is.
A slight change of direction..
There are a few drawbacks to the cheap DNA testing decision. First of all, the cheap DNA testing that can be brought over the counter isn’t the same thing as a paternity test that can stand up as evidence in a tribunal of law. Despite the high drama of shows like Jeremy Kyle, where a DNA test seems to prove paternity, only an approved test by a doctor is recognised by judges.
There is also the issue of accuracy. In the last few years, genetics have become the key area of scientific research, and so it’s become fashionable to search for genetic solutions to medical and social problems. Nevertheless, cheap DNA testing often cuts corners, not checking against all the variables, and offering a less than a hundred per cent accuracy. While this might be fine in most cases, the fraught nature of a paternity test isn’t a site for margins of error.
The accuracy of the genetic test procedures is one of the themes of debate in the scientific community. All medical testing has the potential for laboratory errors. The errors can be due to sample misidentification, chemical contamination, and human errors.
Scientific Testing; There’s Even More……
The possibility of having inaccurate results with genetic tests can lead to serious consequences. Consequently, genetic tests are considered services by the FDA. Thus, no regulations are provided for the assessment of the accuracy and dependability of gene testing procedures. The lack of oversight on the part of the government is the cause of the concern over the accuracy of the results of such tests.
The difference always comes down to the thoroughness of the procedure. Anyone considering DNA testing would do well to examine the technology being used. There is also the issue of additional, hidden costs: the over the counter kit might be tempting, but it often charges extra for analysis.
The biggest differences in DNA testing don’t necessarily come with the actual kit: it is the aftercare that counts. The turnaround time can be different-the significance of this, of course, is contingent on the urgency of the situation.
DNA testing works by comparing the parents’ DNA to the child ‘s, identifying a consistent pattern in the chain of four constituent bases. Some DNA testing kits add additional steps, check more genetic regions or have a specialist approach when treating the DNA. These, however, aren’t always taken into account in the price: yet they’ll impact on accuracy.
Ultimately, a DNA testing kit is most effective if it tests both the mother and the potential father: in many case, this makes the test absolutely accurate.
