About this service

Paroxetine, Serum Level by LC-MS/MS is an accurate test used to measure the concentration of paroxetine, an antidepressant commonly used to treat anxiety and depression disorders. 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.

Treatment Effectiveness: It evaluates whether the current dosage is achieving the desired therapeutic effect on the psychological condition.
Drug Interactions: It identifies any potential interactions with other medications that could affect paroxetine levels.
