Forensic gDNA “finger-printing” in diagnostic virology changed the direction of the investigations; one pointing to a laboratory issue and the other to an intentional deception by the patient. We recommend considering gDNA fingerprinting in any sample discrepancy investigation prior to any public health investigation. This is the first reported use of gDNA analysis in diagnostic virology.
