DNA extraction is the first step in DNA testing. The DNA is then purified and evaluated for quality and quantity.

DNA Testing with RFLP
In the RFLP method of testing, the DNA isolated from the sample is cut into fragments by enzymes. Then, an electric current is used to separate DNA fragments by size. The separated DNA fragments are identified with DNA probes. These probes are pieces of custom made DNA that bind and identify a specific gene locus.


DNA Testing with PCR
In the PCR method of testing, DNA is first isolated from the sample. Individual gene fragments are then synthetically produced in the laboratory and they are labeled with special fluorescent tags. These fluorescent tags enable us to detect the genes with a laser.

Our Laboratory uses BOTH of these technologies because each has distinct advantages and applications in providing you with our guaranteed results. We hold national reputation for performing very extensive DNA testing in all cases.
