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.
