DNA Tests - The Science That Makes It Work
DNA tests are the main method now used to prove paternity and other family relationships, but … how do DNA tests work? Isn't everybody's DNA unique? Do they just check to see if it's the same color? Same size?
Actually, everyone across the world shares
nearly identical DNA. But there are certain
parts of each DNA
code that are specific to certain groups
of people - DNA tests check these sections,
called "Short Tandem Repeats" or STRs for
short.
The STR patterns can be matched up to help confirm biological family relationships and link missing relatives with their families.
The system of matching STRs employed in reputable, accredited labs is based on the FBI's Combined DNA Index System, also known as CODIS.
In the late 1990s, the FBI selected 13 core loci (or STR positions along a DNA strand) that have to be used in any DNA tests submitted to the CODIS database.
Although the FBI developed the system as a criminal justice tool, its strict CODIS rules have become a standard used to judge any lab that performs DNA tests, including those performed for establishing paternity or other family relationships.
Prophase Genetics' DNA tests include the 13 core CODIS loci, along with three others, to ensure identifications that are 99.9+ % accurate.
