Pardon our Progress! 
We are in the process of updating our test pages to include additional clinical and test information.  New, more comprehensive pages will be rolled out over the next several months. 

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.
