Therapeutic drug monitoring

Personalizing medication selection

Therapeutic drug monitoring (TDM), or the quantification of drug concentrations in the blood over time, provides physicians and psychiatrists with a deeper understanding of a patient’s response to therapy.

In certain instances, such as for the management of major depressive disorder, TDM is vital for ensuring optimal treatment concentrations for patients. We offer a robust menu of assays to assist with monitoring antidepressants, mood stabilizers, and more.
