Answer 1

The approach of basing a drug prescription on the results of a single-gene test is called Pharmacogenetics.

What is Pharmacogenetics?

• Pharmacogenetics is the study of how a person's genetic make-up or genes affect how they react to pharmacological therapy. None are better predictors of how the patient will respond to medication than their genetics, but diet, general health, and environment all have a substantial impact.
• By using pharmacogenetics, a healthcare professional can select the medication and dosage that are most likely to be effective for each specific patient.
• The current one-size-fits-all method of medicine selection and dosage may be replaced by therapy tailored to a patient's particular genetic traits some years later.
