New In House Sirolimus Assay

Beginning Tuesday, April 24, 2007, the Clinical Chemistry Laboratory will offer an in house immunoassay for Sirolimus. Values for Sirolimus produced by the immunoassay are on average 25% higher than the current mailout assay which utilizes LC/MS/MS. This is because the immunoassay measures metabolites of Sirolimus not seen in the LC/MS/MS method. Sample requirements remain the same. Assays will be performed on Tuesday and Friday in a batch mode. Samples must be in the lab by 8:00 AM. Questions can be directed to Ronald Feld, Ph.D. at 356-1759.
