Final answer:
Future testing for Hayden may include genetic screening to determine if they have a genetic predisposition for Graves disease. Genetic counseling may also be recommended.
Step-by-step explanation:
Graves disease is an autoimmune disorder that can have a heritable component. To determine if Hayden has a genetic predisposition for the disease, future testing may include genetic screening to identify specific gene mutations associated with Graves disease. This can be done through various methods such as DNA sequencing or polymerase chain reaction (PCR) analysis.
By identifying the presence of certain gene mutations, Hayden can be informed of their risk for developing Graves disease and take appropriate preventive measures or early interventions.
Genetic counseling may also be recommended to help Hayden understand the implications of the test results and make informed decisions about their health.
