Thank you for taking the time to confirm your preferences. To date, evaluations of this technology have generally been limited by small samples and have not considered how these assays should fit into routine laboratory procedures, particularly in smaller, nonreference laboratories. In the PCR method, a pair of primers hybridizes with the sample DNA and defines the region that will be amplified, resulting in millions and millions of copies in a very short timeframe.
