The goal of personalized health care is to tailor your health care to your specific requirements and to design preventive measures and treatments that target your individual needs. Although individualized health has always been the intent of healthcare providers, the ability to do so is evolving.
The new era of personalized medicine intends to use direct knowledge of your genetic make-up to devise a plan of care with greater precision. For now, it is not feasible to map the genome of every individual. So, when genetic information is not available, family history serves as a surrogate.

Many diseases and disorders have the potential for being inherited from one generation to another. Family medical history (your medical pedigree) is a means of establishing a pattern of disease in family members and of identifying other members who may be at risk for inheriting that disease. It is an indirect indicator of the risk for developing the same or a similar disorder. Geneticists also use this information to generate a pedigree chart (genogram) to determine how a genetic trait may have been inherited.
Family history is an important part of your health history.
