How does the testing process work?
Testing is performed using the latest PCR (Polymerase Chain Reaction) technology combined with the Identifier system for analysis. Our lab uses PCR DNA genetic analyzers that are the very latest in technology, used most recently in the Human Genome Project. The Identifier system allows us to test 16 unique DNA loci for each person – three more than the 13 DNA loci used by the FBI in establishing their standard for human identification. As an added measure of reliability, each test is independently run twice, and the results from each run are compared for accuracy. Each test is reviewed and approved by at least one Ph. D. director experienced in paternity testing. In 2002, our lab became the first in the paternity testing industry to truly run every DNA twice from beginning to end. The American Association of Blood Banks requires only ‘exclusion’ tests to be run twice, but to ensure complete confidence in your results, we have taken our testing several steps further. Our laboratory empl
1. Sample Collection. DNA testing starts with sample collection. You collect your samples using the simple, easy-to-use Beta Self-Collecion™ Kit. It contains a buccal (cheek) swab, a cotton-like swab rubbed against the inside of thecheek to gather loose cells. Please read our Sample Collection page for more details. When samples reach our lab, we divide the samples to perform the test twice independently, ensuring accuracy of results. 2. DNA Extraction. We use special chemical agents to extract and purify DNA from the buccal swabs. This procedure also separates DNA from other materials found in the cells. 3. PCR. We use the Polymerase Chain Reaction (PCR) to create a DNA profile from each person’s sample. Each sample is placed in a thermal cycler (PCR machine) along with 16 fluorescent primers. These primers detect specific “loci” or locations on the DNA. During PCR, the thermal cycler takes the DNA sample mix through 30 cycles of heating and cooling. This molecular xeroxing process ma

Testing is performed using the latest in PCR (Polymerase Chain Reaction) technology combined with the IdentifilerT system for analysis. The laboratory, DNA Diagnostic Center, uses PCR DNA genetic analyzers that are the very latest in technology, used most recently in the Human Genome Project. The IdentifilerT system allows us to test 16 unique DNA loci for each person tested three more than the 13 DNA loci used by the FBI in establishing their standard for human identification.
