High Quality Data and Comprehensive Results

When considering molecular genetic testing, there is nothing more important than the clinical laboratory’s commitment to diagnostic accuracy. At the Johns Hopkins Genomics 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.
