Precision Health is a medical model that proposes the customization of healthcare, with medical decisions, treatments, and practices being tailored to an individual based on their genetics, rather than one-size-fits-all. Precision Health helps healthcare providers better understand the many things that play a role in a patient's health. Knowing a patient's genetic makeup lets them more accurately predict which treatments will be most effective and safe as well as how to prevent illness from starting. This is part of a movement in the healthcare industry, of evolving past the current reactive state to a proactive, preventative state.
