Therapeutic (reference) ranges for immunosuppressant drugs
have
generally not been well established, as these tend to vary
depending on the type of transplant, patient clinical status
and
post-transplant duration/course, concomitant use of other
pharmacologic agents of the same class, the dosing/collection
intervals and other known factors. This range is based upon
commonly published guidelines, and any results are subject to
physician interpretation and should be used in conjunction with
other diagnostic and clinical information.
