How many genetic systems (markers) should be run?
LabCorp is pleased to be the first national DNA laboratory to offer a 21-marker genetic analysis, in combination with our standard double-blind process, on every paternity sample in every paternity case. These multiple genetic systems selected for routine testing at LabCorp on average will exclude 99.9999% of falsely accused men from paternity. In the extremely rare case in which the 21-marker genetic analysis does not provide a clear result, LabCorp has other genetic test options to further narrow the results.
