What You Should Know About DNA Testing

Our understanding of DNA and its connection to virtually every aspect of human life has led to some of the most exciting and important breakthroughs in medical history. Genomics, which is the science responsible for studying and mapping DNA strands, originated in the 80s and now provides the framework for modern DNA testing. Although the practice is a moderately recent one, people across the globe are beginning to recognize the benefits of performing a DNA paternity test and other uses of genomics.

How Does DNA Testing Work

Maternity and paternity DNA testing is accomplished by comparing DNA fragments obtained from a mother or father and prospective offspring. A successful match is one that yields a correspondence of above 50-percent. In other words, the higher the number of paired genetic loci (which is the placement of genes on the chromosome) the greater the feasibility of family relation. Garnering a perfect match would be physically impossible, unless the two subjects were completely identical, but a score that reaches just under 100-percent (preferably 99-percent) is always desirable. For accurate results, doctors will compare between 12 and 16 strands, sometimes more. Generally, the more loci examined the higher the test accuracy each subject can expect to achieve.

Although the science is often associated with DNA paternity testing, it offers a wide range of benefits from which almost everyone can profit. Of course, matching children with biological parents has become an asset to our judicial system, but with the emergence of numerous private DNA testing ancestry labs, companies have begun finding ways to appeal to the rising fascination with ancestral lineage. Through facilities operated by companies like ProHealth, customers can discover variations that have occurred in their DNA, linking them to genomes retrieved from alleged ancestors.

Benefits of DNA Testing

Testing can also have a number of practical benefits which can help patients understand health risks and answer questions about various medical concerns. For example, someone might find information hidden in DNA that could warn about a possible vulnerability to certain types of cancer. For prospective parents, genetic tests could be useful in helping them decide whether to have children. Perhaps a test reveals a likelihood of serious deformities or psychological disabilities. Couples can then make informed decisions about what type of illnesses they are willing to accept and which ones they would rather avoid. For those who choose to birth a disabled child, knowing ahead of time can help prepare for the challenging road in front of them.

As technology improves, the uses and benefits of DNA testing have become increasingly vast. Preimplementation genetic diagnosis is just one example of the groundbreaking leaps forward researchers have made during the past few years. This process is a form of genetic testing that allows a female patient to choose, from among artificially fertilized embryos, which egg to insert in her uterus. By using this method of impregnation, doctors can inspect chromosomes for complications, enabling couples to ensure the development of a healthy fetus.
