Genetic testing, also known as DNA testing, is used to identify changes in DNA sequence or chromosome structure. Genetic testing can also include measuring the results of genetic changes, such as RNA analysis as an output of gene expression , or through biochemical analysis to measure specific protein output.

Highly accurate DNA parental testing became available in the 1980s with the development of RFLP. In the 1990s, PCR became the standard method for DNA parental testing: a simpler, faster, and more accurate method of testing than RFLP, it has an exclusion rate of 99.99% or higher. [13]
Genealogical DNA tests have become popular due to the ease of testing at home and their usefulness in supplementing genealogical research. Genealogical DNA tests allow for an individual to determine with high accuracy whether he or she is related to another person within a certain time frame, or with certainty that he or she is not related.
The DNA in the first three samples was too degraded to use. However, on the fourth, more than enough DNA was found. The test, which has a degree of accuracy acceptable in UK courts, proved that a man named Patrick Coyne was her biological father. [126] [127]
The results of this test provide percentages of a DNA associated with general regions or specific ethnic groups (e.g. Western Europe, Asia, Jewish, Native American, etc.). Notably, unlike other testing companies, they chose to strip out markers for mendelian medical issues, [23] [24] [25] mtDNA results, and Y-DNA SNP results.
