Therapeutic Drug Monitoring: TDM

Therapeutic drug monitoring (TDM) is testing that measures the amount of certain medicines in your blood. It is done to make sure the amount of medicine you are taking is both safe and effective. Most medicines can be dosed correctly without special testing. But for certain types of medicines, it can be hard to figure out a dose that provides enough medicine to treat your condition without causing dangerous side effects. TDM helps your provider find out if you are taking the right dose of your medicine. Total drug concentrations in plasma, blood, and tissues can be measured in various ways. Because of selectivity, sensitivity, and ease of use, liquid chromatography-tandem mass spectrometry (LC-MS/MS) is the most common analytical choice. Stable isotope-labeled drugs have become the gold standard for mass spectrometry detection because of their high sensitivity and lack of matrix effects[1][2].
