How To Make Sure DNA Testing For Genealogy Is Carried Out Accurately
DNA testing for genealogy is one of the most common uses for what is still a revolutionary technology. The accuracy of any given result will depend entirely on the age and quality of the DNA samples, and the testing procedures used. Where samples are taken from living people and analyzed quickly, there is a very high degree of accuracy.
This accuracy rate diminishes as risk factors are introduced. Many of these risk factors are unavoidable, because they involve using tissue which is old and to a certain extent degraded. Even so, it can still give a high indication of probability. DNA testing itself is still a relatively young technology, and the testing procedures are by no means fully developed.
When the technology was first developed in the 1980s, the potential was so great that people started to make exaggerated claims as to what could be done with it. Here was the science which was going to allow every crime to be solved, and lead us into a future where we could be crime free because the chances of getting away with crime would be virtually nil. It hasn’t happened, of course, and there are sound reasons why it never will.
How Is DNA Testing For Genealogy Different?
DNA testing for genealogy is very different from crime DNA testing, although there can be a significant overlap depending on circumstances. If the genealogy samples which are being tested are taken from living people in the here and now, there is a greatly reduced risk of complication. The main consideration will be to make sure that any equipment used will be free of contamination.
This may sound obvious, but there are far too many cases where it has been sadly neglected. Where family DNA testing involves using samples from exhumed bodies, or DNA from items which one belonged to a deceased family member, there is a far greater risk of contamination producing a flawed result.
Even in high profile criminal cases where the reputation of someone accused and convicted of a capital crime is at stake, there is often considerable controversy surrounding the test results. This is even more the case when techniques are used which magnify small parts of the overall DNA sample.
The Cost Of DNA Testing For Genealogy
The expense of DNA testing for genealogy can also vary greatly from one case to the next, depending on how the samples which are going to be tested are obtained. Make sure that you get proper quotes and estimates before you order any work to be carried out or go out and get a DNA test for your genealogy.
Get the full quote for everything before you have any of the work carried out, because you do not want to spend money on the initial stages only to find out that you then cannot afford to complete the more expensive parts of the job. There can be hidden costs with DNA testing for genealogy.
