Peroxisomal Diseases Testing

Below is a list of tests offered through the Peroxisomal Diseases section of the Genetics Laboratories at Kennedy Krieger Institute. Please download the Peroxisomal Diseases Test Requisition Form for pricing, sample, and shipping requirements. The completed form should accompany the samples you send for testing.
