Lysosomal Diseases Testing Laboratory
The Lysosomal Diseases Testing Laboratory (LDTL) at Jefferson Medical College specializes in the testing of patients suspected of having one of these genetic disorders. This laboratory was established in 1973 by David A. Wenger, PhD, and currently receives the largest number of samples for these diseases in the world. Testing has resulted in the diagnosis of over 4,000 individuals.
