Providing Blood Specimens to Researchers Across the World Our Specimens Inventory includes over five million residual newborn screening dried blood spot specimens representing nearly every Michigan birth since 1989. Dried Blood Spots Specimens and MDHHS Data After obtaining the appropriate approvals MDHHS can link blood spot specimens to Michigans public health registries making it possible to request deidentified and nonunique specimens with a known health outcome. Important Resource Over 160 biomarkers and compounds have been measured in dried blood spots from DNA and proteins to metals and infectious agents. They are an excellent source of specimens for both epidemiological investigations and studies of how genes interact with the environment as well as for assay development.
