Pharmacodiagnostic testing
Pharmacodiagnostic Testing
Pharmacodiagnostic testing (pronunciation: far-ma-ko-die-ag-nos-tic tes-ting) is a type of medical testing that is used to determine the most effective drug therapy for a patient based on their individual genetic makeup.
Etymology
The term "pharmacodiagnostic" is derived from the Greek words "pharmakon" meaning drug, and "diagnostikos" meaning able to distinguish or recognize.
Definition
Pharmacodiagnostic testing, also known as pharmacogenomic testing, involves the study of how genes affect a person's response to drugs. This relatively new field combines pharmacology (the science of drugs) and genomics (the study of genes and their functions) to develop effective, safe medications and doses that will be tailored to a person's genetic makeup.
Process
The process of pharmacodiagnostic testing involves taking a sample of a patient's blood or saliva and sending it to a lab for analysis. The lab then examines the patient's DNA to look for specific genetic variations that may affect how they respond to certain medications. The results of this test can help doctors predict how a patient will respond to a drug, and can guide them in choosing the most effective drug and dosage for that patient.
