The words "DNA testing" are most commonly associated with DNA paternity testing. We hear the term most often on television talk shows or perhaps in television courtrooms.
Paternity means fatherhood. Paternity is established when a paternity testing laboratory uses genetic testing methods to demonstrate that an alleged father is the biological father of a child. These DNA paternity tests are performed to a legal standard. Paternity is disproved when these same methods and standards demonstrate that an alleged father is not the biological father.
DNA (deoxyribonucleic acid) is the genetic material in the cells of your body that govern inheritance of the color of your hair, eye color, your build, bone density and many other human and animal traits. DNA is a long, but narrow string-like object. A one-foot long string or strand of DNA is normally packed into a space roughly equal to a cube 1-millionth of an inch on a side. Not only does the human body rely on DNA but also so do most living things, including plants, animals and bacteria.
Every nucleated cell has 46 chromosomes, except the sperm cells from the man and the egg of the woman that only contain 23 chromosomes each. At the moment of conception, there are 46 chromosomes necessary to create a person. Thus, a person receives half of his/her genetic material or DNA from the biological mother, and the other half from the biological father.
Our body's cells each contain a complete sample of our DNA. There are muscle cells, brain cells, liver cells, blood cells, sperm cells and others. Basically, every part of the body is made up of these tiny cells and each contains a sample or complement of DNA identical to that of every other cell within a given person.
Every person's DNA is unique except for identical twins. Since it is so specific, just like a fingerprint, DNA paternity testing is the most powerful form of testing. DNA paternity testing is much more than a blood test. It can be performed on a much wider variety of samples, including blood cells, cheek cells, tissue samples, and semen. Since blood types, such as A, B, O, and Rh are more common within the general population; the power to differentiate individuals is not as high as with DNA paternity testing. Typical DNA test results are often 10 to 100 times more accurate than what the courts require.
Years ago, DNA testing required laboratory presence; however, there are now numerous types of home DNA tests available for use. These DNA test kits are available by direct shopping, mail order or online. The cost for these home DNA tests varies, depending on your specific desires. With a little research, you can even find a free DNA test. Most home DNA test kits are basically the same and are easy to use. For example, a basic, easy to use DNA paternity test kit may cost approximately $200.00. This low-cost DNA test kit is often used for proving paternity to a doubting father or for people who are simply looking for confirmation and peace of mind.
For approximately $225.00, a DNA test providing over 10 times more accuracy than the basic DNA test kit is available. Those with serious doubts concerning paternity and who want a higher accuracy rate than the basic DNA test kit commonly use this kit. Again, popular for those people who want that extra accuracy rating for peace of mind.
For those who simply have to have the best and are willing to pay for it, there is a higher accuracy rate DNA test kit available. This enables the parties to obtain an impressive accuracy rate that is offered by very few labs in the world. Keep in mind that DNA testing in itself is 99.999% accurate. The increased costs reflect the laboratory and higher accuracy rate of the type of test.
