Biomarker Assay Laboratory (BAL)
For more than 30 years, NCRAD has been a key research infrastructure for NIA to support ADRD research. NCRAD’s mission has grown from a DNA storage repository for genetic studies to a specialized research repository that supports a broad range of biospecimens and focuses on the aspects of sample collection, storage, distribution, and processing. NCRAD’s success is driven by the use of standard operating procedures to ensure uniformity and to minimizing the impact of preanalytical variables on downstream sample analyses.
With the establishment of the Biomarker Assay Laboratory (BAL), NCRAD has expanded our services to include processing of well-established fluid-based biomarkers and provide more support to research studies. The goal is to ensure standardized processing and reliable research biomarker results. This approach allows for longitudinal quality monitoring and consistent delivery of results over time, as well as the opportunity for cross-laboratory comparability studies.
Plasma assays currently available in the BAL:
- P-tau 181
All assays processed at the NCRAD Biomarker Assay Laboratory are research-based results only. For investigators interested in CLIA results, requests can be facilitated by NCRAD, in collaboration with C2N.

Uniform Sample Collection
To ensure the highest quality and most consistent assay results, NCRAD recommends standard uniform collection of biospecimens as outlined by the Standardization of Alzheimer’s Blood Biomarkers (SABB) working group.

NCRAD recommends the use of polypropylene for all collection and processing materials.
