Of the myriad of drugs approved by the FDA and used clinically, there are relatively few that are routinely monitored by clinical laboratories. The four major classes of drugs that are frequently monitored by TDM are:
- Antibiotics
- Anticonvulsants
- Immunosuppressants
- Cardiac medications
There are other drugs monitored by TDM that are not included in any of the above classifications, but the vast majority of TDM testing is performed for drugs that are included in one of these four categories.
