When considering molecular genetic testing, there is nothing more important than the clinical laboratory’s commitment to diagnostic accuracy.  At the Johns Hopkins DNA Diagnostic Laboratory – a non-profit, academic service lab established in 1979 – we fulfill this commitment through insistence on high quality data and comprehensive result interpretation. The highest of standards, where modern medicine was pioneered – that’s what the world has come to expect from Johns Hopkins.
