Beta‑Globin Gene Dosage Analysis
Also known as: Beta-Globin Deletions, Beta-Globin Duplications, HERED Persist of Fetal HB (Deletional), HPFH (Deletional), Deletional HERED Persist of Fetal HB
Clinical Use
Order TestUse
Detects deletions or duplications in the β‑globin (HBB) gene that may not be identified by sequencing alone, useful in patients with suspicion of β‑thalassemia where sequencing is negative or in cases such as discordant parental genotypes or more severe anemia suggesting gene dosage abnormalities.
