Recommendations when to order or not order the test. May include related or preferred tests.
May be used to identify HBB gene deletions associated with beta thalassemia, elevated hemoglobin F (such as in hereditary persistence of fetal hemoglobin [HPFH] or delta beta thalassemia), or to confirm gene fusion hemoglobin variants (e.g., hemoglobin Lepore). Inform the laboratory if patient has received gene therapy; test interpretation may be impacted in such cases. For example, certain gene therapies may impact the performance of this test and interpretation of this result; the presence or absence of variants, zygosity, and HBB gene copy number may not be determined in such cases. Inform the laboratory if patient has received gene therapy by submitting the patient history form linked below.
