Collect

Lavender (EDTA) or pink (K2EDTA).

Specimen Preparation

Transport 1 mL whole blood. (Min: 0.25 mL)

Storage/Transport Temperature

Refrigerated.

Unacceptable Conditions

Serum or plasma. Specimens left at room temperature for longer than 24 hours. Clotted specimens.

Ambient: 24 hours; Refrigerated: 2 weeks; Frozen: 2 months

Special Handling Instructions

Use this code if a patient presents without a kit or if ordered on an inpatient who does not have their own kit. 
As of November 2013, order this if transplant patient has no kit. Fax results to UW.

Trough levels should be drawn.

Reference Interval

Effective November 17, 2014
Therapeutic Range:
Cyclosporine A, Therapeutic Range100-400 ng/mL
Kidney transplant (in combination with Everolimus)1 month post-transplant: 100-200 ng/mL
2-3 months post-transplant: 75-150 ng/mL
4-5 months post-transplant: 50-100 ng/mL
6-12 months post-transplant: 25-50 ng/mL
Heart transplantUp to 3 months post-transplant: 350-525 ng/mL
4 months and older post-transplant: 145-350 ng/mL
Liver transplant290-525 ng/mL
Toxic valueGreater than 700 ng/mL

Interpretive Data

The general therapeutic range for cyclosporine A is 100-400 ng/mL. The optimal therapeutic range for a given patient may differ from this suggested range based on the indication for therapy, treatment phase (initiation or maintenance), use in combination with other drugs, time of specimen collection relative to prior dose, type of transplanted organ, and/or the therapeutic approach of the transplant center.

Notes

Cyclosporine (Sandimmune) whole blood concentrations can be measured by either chromatographic or immunoassay methodologies. These two methodologies are not directly interchangeable, and the measured cyclosporine whole blood concentration depends on the methodology used. Reference ranges may vary according to the specific immunoassay or HPLC-MS/MS test. Generally, immunoassays have been reported to have a positive bias relative to HPLC-MS/MS assays due to the detection of antibody cross-reactivity with cyclosporine metabolites.
