Philosophy
The DNA Diagnostic Laboratory is a non-profit, academic service lab
established at Johns Hopkins in 1979. We believe that when
considering molecular genetic testing, the most important attribute of a
clinical laboratory is commitment to diagnostic accuracy. We
fulfill this commitment through insistence on high quality data and
comprehensive result interpretation.

Weather Update:
February 9, 2010:
Due to extreme winter weather conditions in the Mid-Atlantic, the lab
may not be able to open and receive samples and courier companies may
not be able to adhere to regular delivery schedules over the next
several days. During this time, please do not send CVS or
cultured cell samples to the laboratory. You may call the
laboratory for updates or options at any time (410-955-0483).
Even if the lab is closed, phone calls will be returned. You may
continue to ship samples such as blood or extracted DNA.
