Components
Reference Interval
  N-acetylprocainamide (NAPA) 6.0-20.0 µg/mL
Toxic: 35.1 µg/mL or greater
  Procainamide 4.0-10.0 µg/mL

Interpretive Data

The commonly expected therapeutic range for the sum of NAPA and Procainamide is 5-30 ug/mL. However, the concentration of NAPA is dependent on many factors, including; time of last procainamide dose, mode of administration, concomitant drug therapy, sample condition, time of sample collection and individual variations in absorption, biotransformation, distribution and excretion. Therapeutic ranges are provided only as a guide for interpretation along with other clinical symptoms and patient history.
