|Test Update Information||Effective July 18, 2016, everolimus testing will be performed in-house at China Basin Chemistry using an immunoassay method. The therapeutic range and potentially toxic concentration remain the same.|
|Performed by||China Basin Chemistry|
|In House Availability||Daily, day shift only|
|Method||Abbott Architect chemiluminescent immunoassay|
|Collection Instructions||Trough levels should be collected just before next dose.
NOTE:If patient is taking everolimus AND sirolimus, this immunoassay should not be run to determine the everolimus concentration of the sample. The clinicians should order a MOLT with "ARUP everolimus
|Container type||Lavender top|
|Amount to Collect||3 mL blood|
|Sample type||EDTA whole blood|
|Preferred volume||3 mL blood|
|Min. Volume||1 mL blood|
|UCSF Rejection Criteria||Non-EDTA whole blood samples|
|Processing notes||Refrigerate sample.
NOTE: If MOLT order for "ARUP everolimus mass spec assay" is received. Please order ARUP test #0092118 (everolimus by LC-MS/MS). Ship refrigerated.
Note: this therapeutic range is based upon use of everolimus in adult patients to prevent rejection after receiving a kidney transplant. The therapeutic range for the use of everolimus in other indications has not yet been established and may vary from the range documented here.

|Synonyms||Afinitor; Certican; Zortress|
|Stability||Refrigerated 3 days, frozen 28 days.|
|Turn around times||For samples received by 1200 (Monday-Friday) and 1000 (weekends and holidays) the results will be available by 1600. Results for samples that miss the cut-off times will be available the following day.|
|Additional information||This everolimus immunoassay has SIGNIFICANT cross-reactivity with sirolimus. If a patient is on both everolimus and sirolimus, DO NOT order this everolimus immunoassay. Please order a "miscellaneous outside lab test" and write "ARUP everolimus mass spec assay" in the notes section
NOTE:If patient is taking everolimus AND sirolimus, this immunoassay should not be run to determine the everolimus concentration of the sample. The clinicians should order a MOLT with "ARUP everolimus mass spec assay" written in the notes section. Please order ARUP test #0092118 (everolimus by LC-MS/MS). Ship refrigerated.
