Comments:
Analysis performed using the Abbott Diagnostics Cyclosporine
immunoassay on the Architect platform. The general therapeutic range
for cyclosporine is 100-300 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. Cyclosporine whole
blood concentrations can be measured by either immunoassay or
chromatographic 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.
Methodology:
