Specimen Type: Red OR Lav (EDTA) tube.
Frequency: 3 – 5 days
Instructions: 1.2 mL Serum or Plasma from Red OR Lav (EDTA) tube., Ambient. Min 0.3 mL.
Text: Used to monitor therapeutic levels; evaluate toxicity. Mycophenolic acid (MPA) is the active metabolite of the prodrug, mycophenolate mofetil (MMF). Absorption of the prodrug is rapid following oral administration to the extent that detectable levels are not seen. Similar effects are observed after cessation of IV administration.
Methodology: Liquid chromatography/tandem mass spectrometry (LC/MS-MS)
