Brigham Research Assay Core

The mission of the BRAC Laboratory is to provide a comprehensive menu of state-of-the-art high-quality research assays to the Partners and non-Partners research communities at competitive costs. The BRAC Laboratory is a dynamic entity seeking to meet the needs of its investigators with new and relevant technologies, and evolving research support. In addition to the immunoassay technology, BRAC offers testing using Equilibrium Dialysis and LC-MS/MS platforms. BRAC's portfolio of LC-MS/MS tests include hormone assays: Testosterone, 25-OH vitamin D2/D3, Estradiol and Estrone, and DHT with additional assays being added in the future as we develop more precise methodology to analyze small molecules, and potentially non-human specimens.



  • Provide assays in a timely manner at high quality and low cost

  • Offer access to investigators to unique or rare assays

  • Provide the flexibility to add new or previously unavailable assays

  • Offer individualized consulting and experimental assay design


BRAC is a CLIA certified laboratory and is accredited by the Joint Commission.

***Please Contact the Core for External Pricing, any externally funded testing is subject to Overhead Rates***
The internal user fee was calculated based on the direct costs of providing each service. A Partners investigator using a Partners fund is considered an internal user. The external user fee comprises the direct fee charged to the internal user plus an overhead component. External users are identified as investigators (Partners-affiliated or non-Partners-affiliated) and institutions that use non-Partners funds to pay for research core services. 

**Special Requests 
The indicated tests are also available upon request, but are not part of the standard test menu. There may be additional charges if the kits are not fully used.
