Pharmacogenetics refers to genetic effects on drug response and drug metabolism. The response and sensitivity to a medication can vary between individuals due to genetic factors.
As many as 50% of the people who take a medication may not respond to it due to genetic variations. These individuals do not derive any benefit from the drug, and are unnecessarily exposed to all the side effects. Research is beginning to elucidate the genetic variations that cause some individuals to not respond to a medication.
For people who do respond to a medication, there may be differences in response among individuals due to genetic variations. Individuals may metabolize drugs differently, and therefore require different doses for optimal efficacy and reduced side effects.
Genomic Express offers genetic tests that facilitate selection of the most appropriate medication for an individual, as well as the optimal dosage of the drug.
