Genetic testing for HSP may be considered if the presentation and family history suggest the condition. Confirmation of a diagnosis of HSP results in an expectation for slower disease progression and a more limited range of clinical involvement, and affects management of the patient. Appropriate genetic counseling should be offered to patients with suspected HSP before they are referred for genetic testing.
