Using the TDM service
The assay service is routinely available Monday to Friday, 9am-5pm. For urgent assay requests, please contact the unit in advance. The unit will report on non urgent assay requests within 3 working days of receiving the sample in the laboratory, excluding weekends or bank holidays.
Sample type
The matrix of choice is serum or plasma, and although they can be used inter-changeably it is preferable to use one or the other. In most clinical settings the measurement of total serum concentrations will suffice and indeed most routine methods for measuring AEDs in sera do not discriminate between the component of drug that is free (unbound) and that that is bound to serum proteins.
