In order to help resolve variants of uncertain significance (VUS) in our panel test results, Invitae offers follow-up testing to selected family members of patients previously tested at Invitae, at no additional charge. This service is available when testing additional family members may clarify the disease-variant relationship. The goal is to better understand the clinical impact of the variant and, when possible, to decrease the uncertainty of the original test result. Ask your healthcare provider to contact Invitae if VUS resolution was recommended on your test report. For additional information about Invitae's VUS resolution program, please see our VUS resolution page.
