A new technique has been developed for the accurate measurement of 1,25-dihydroxyvitamin D3 (1,25(OH)2D3) using mass spectrometry. The assay is specific for 1,25(OH)2D3, and it can be performed in a matter of minutes with simple sample preparation protocols. Vitamin D3 is critical to many physiological processes, and 1,25(OH)2D3 is its active metabolite. A 1,25(OH)2D¬3 deficiency can lead to organ and bone disorders, while excess 1,25(OH)2D3 is associated with digestive disorders and ischemic heart disease. Therefore, measurement of 1,25(OH)2D3 is an emerging tool in preventative medicine. Existing diagnostics are plagued by inaccurate and irreproducible results, and this new diagnostic technology can potentially overcome these issues.


The assay may be used as a clinical diagnostic for measuring 1,25(OH)2D3 from human serum samples.


Stage of Development

Proof of concept studies have been completed for the measurement of 1,25(OH)2D3. Quantitative assays and kits are being developed, and Georgetown is seeking a partner for further development and commercialization.
