Below are a few basic processes followed throughout DNA testing. The general procedure entails:
• Isolating DNA from a sample containing the needed DNA of unknown origin, as well as isolating DNA from the test sample (e.g., blood, semen, skin tissue, or saliva) from a known individual.
• Processing the DNA to obtain test results
• Determining the variations in the DNA test results (or types) from specific regions of the DNA
• Comparing and interpreting the test findings from the unknown and known samples to have a conclusion.
