The use of pharmacogenomic testing to help determine courses of therapy is gaining momentum as evidence accumulates showing which genotypes respond best to particular medications. Pharmacogenomics describes the process whereby pharmacists and physicians analyze information about a person’s particular genetic makeup in order to match it to a medication or dosage that will work best for that person.

In the past, one kind of standard issue medication was prescribed for a particular condition, regardless of who was getting it. Pharmacogenomics, however, enables healthcare providers to get a look at a person’s DNA to see how he or she metabolizes or responds to various medications. It can help determine which medications to use and which to avoid.
