Why People May Need Services For Testing DNA in San Diego

People often need services for testing DNA in San Diego if there is any question about a child's paternity. This scientific method is the only reliable way to determine if a man has fathered a child. It is a process that is accurate and has been used worldwide for more than a decade to identify genetic links between people. It has been used for many different purposes.

What this is?

Deoxyribonucleic acid is a substance found within the body that has a sort of encrypted code. It gives a considerable amount of information about a person that can be used in a variety of ways. The amount of information that can be gleaned from this material includes information about a person's hair and eye color, ethnic background, and other details. It has been used in a variety of ways for both living people as well as to tell scientists more about ancient cultures. It can be obtained from most physical sources that include blood, saliva, hair and even skin cells. For studying ancient cultures, it may be necessary to obtain marrow from inside of a bone to get information. For most modern purposes, a simple saliva swab will do the trick.

How it can be used?

This test has many purposes. One of the most common ones that people are familiar with is in crime fighting and forensics. This can be used several different ways. One is to determine the identity of murder or accident victims when the identity is not obvious. These may prove to be a match to a known person or it may be something that can be stored for when a match does come up. Criminals an also be identified using this technique. This can use saliva, blood or semen found at the scene of the crime. Sometimes a match can be found using a national database of this kind of information.

The most common uses for most people

There are two very common reasons people use this kind of testing. Both are to identify kinship between people. One is often used to determine paternity while the other can be used for genealogical research.

Men and women often need help in determining the paternity of a child. Men want to know that the child is theirs or they may have a need to defend a false claim in court. Women often need this service to compel a biological father to pay child support. Once testing has determined the validity of a claim or totally excluded someone as being the father, a legal determination can be made. This has helped many men to avoid paying support for an unrelated child but it has also helped mothers to collect child support where due.

People that are interested in genealogy can use this testing in two ways. One kind of testing will show a person which ethnic groups their background contains. There are often surprises of all kinds as most people are a mixture of many different groups. The other way that this can be used is to establish kinship within different family trees. People with very common last names in the family tree are often interested in this kind of test because of its precision in identification.
