The analysis relies on an advanced technique that combines liquid chromatography and tandem mass spectrometry (LC-MS/MS), ensuring precise and reliable results. This test helps doctors evaluate the effectiveness of the treatment, adjust the appropriate dosage, and confirm that there are no negative interactions with other medications. It can be particularly useful in cases where dosage adjustments are needed or when side effects appear.
