Advances in Scientific Testing

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.

Dentists Investing in Quality Care Tools

We look to our dentists as guides on the road to dental health. While it is up to us to maintain our own oral hygiene to the best of our abilities through regular brushing, flossing, and oil pulling, in the end, it is the dentist and the hygienist who determine whether we have done a good job.

Most of us probably do not give much consideration to the equipment our dentist uses, but one can usually tell when it is lacking. If that is the case, the dentist is likely cutting corners or not using quality dental equipment providers. This reduces their ability to give your teeth proper treatment and can even lead to problems down the road for you.

You might not be able to spot quality dental instruments when you see them, but as a client, you have the right to ask your dentist about the equipment they are using on you. You can ask such questions as:

  • How often do you clean your equipment?
  • How often are the drill heads replaced?
  • How many times can my mouth be X-rayed before there could be excessive radiation exposure?


While a dentist and their hygienist(s) are highly trained, they are really no different than any other professional who provides you with a service. Do you feel intimidated asking your mechanic about the parts they use on your car? Probably not. Don’t be afraid to ask your dentist questions about their equipment and practices.

Chances are, they will be happy to provide the answers you seek. If they are evasive or rude about such a basic question, that is not a good sign. Any professional should be open about the way they work, so if answers are not forthcoming that meet your satisfaction, it might be time you consider switching providers.
