Reference Testing

Reference Range

Steady-state serum or plasma levels from patients on a daily regimen of 30 to 60 mg Citalopram: 9-200 ng/mL.

Steady-state peak plasma levels from patients on regimen of 10 or 30 mg/day: 21 and 64 ng/mL, respectively, and occur at approximately 4 hours post dose.

This test is not chiral specific; therefore, Citalopram and/or Escitalopram may be present. Patients who have taken Racemic Citalopram (Celexa®), as opposed to Escitalopram (Lexapro®), within the past 3 days may have falsely elevated values.
Analysis by High Performance Liquid Chromatography/Tandem Mass Spectrometry (LC-MS/MS).
