Is there a way to test for suspected under- or malabsorption of antidepressant or atypical anti-psychotic medication? can all be tested the same way?

Psychopharmacogenomi: the recent introduction of testing for genetic profile and how meds are absorbed, transported & utilized by the body has been of great help in recognizing and identifying patients that either rapidly or slowly metabolize medications. so testing can shed light on how your body handles these meds and give some guidance ( not definitive) in using meds in your case. good luck and feel better
