Final answer:
Pharmacogenomics can be used to assist patients taking warfarin by analyzing their genetic information to determine their personal response to the medication.
Step-by-step explanation:
Warfarin is a medication commonly used to prevent blood clotting in stroke or heart attack patients. However, it can result in an overdose in some patients depending on their liver function. Pharmacogenomics can be used to assist these patients by analyzing their genetic information to determine their personal response to warfarin and adjust the dosage accordingly. This approach allows for personalized medicine and reduces the risk of adverse effects.
