Specimen

  
Serum
  
2.0 mL
  
0.5 mL
  

A steady state, trough (pre-dose) sample is generally accepted as most consistent for therapeutic drug monitoring of Lamotrigine.

  

Red:

  1. Allow sample to clot
  2. Spin
  3. Transfer serum to a False bottom plasma/serum transport vial/tube (AHL), labelled as serum, within two (2) hours of sample collection

Gold:

  1. Allow sample to clot
  2. Spin
  
EDTA plasma
Lithium heparin (Li hep) plasma
Sodium heparin (Na hep) plasma
  

Immediately following collection, mix sample thoroughly by gently inverting 8 - 10 times

  

Light green:

  1. Spin

 

EDTA/Sodium heparin (Na hep):

  1. Spin
  2. Transfer plasma to a False bottom plasma/serum transport vial/tube (AHL), labelled as the appropriate plasma type, within two (2) hours of sample collection

Clinical and Interpretive info

  

Therapeutic: 3.0 - 15.0 µg/mL

  

The target steady state trough range for seizure control is 3.0 - 15.0 µg/mL.

Concentrations that exceed 15 µg/mL may contribute to adverse effects. Patient response varies widely, particularly with co-medications and/or compromised renal function.
