Pre-dose sampling is useful for checking patient compliance or suspected toxicity.  A universal reference range is not applicable.  Correlation between pre-dose plasma levels of total MPA and clinical outcome depend on the specific clinical setting/patient population.

Collect specimen prior to dose.  Record the amount and date/time of last dose, and specimen collection time on request form.
