Developing DNA Testing
Techniques for DNA testing have changed dramatically over the past century. They have been fine-tuned over the years in
an effort to increase accuracy and improve the
power of exclusion
for DNA testing.
In the early 1900s, the first attempts of
genetic
testing
were made with the advent of blood typing. Quickly thereafter, techniques with higher powers of exclusion were adopted through
serological and HLA tests. It was only in the 1980s that scientists began using DNA characteristics as evidence of biological relationships.
The evolution of techniques has led to an increase in the power of exclusion to more than 99% in many cases.
