Beta-Thalassemia: HBB (Full gene sequencing)

Alphabetical Test listing

Beta-Thalassemia: HBB (Full gene sequencing)-994

Beta-Thalassemia: HBB (Full gene sequencing)
  • Confirm a clinical diagnosis of β-thalassemia
  • Detect carriers
  • Help to establish a prognosis

This method does not reliably detect mosaic variants, large deletions, large duplications, inversions, or other rearrangements or deep intronic variants. It may be affected by allele-dropout, may not allow determination of the exact numbers of T/A or microsatellite repeats and it does not allow any conclusion as to whether two heterozygous variants are present on the same or on different chromosome copies.

DNA sequencing



Normal equals reference sequence or variants that are known or predicted to be benign.

Abnormal equals all other variants.


This test covers all coding nucleotides of gene HBB, plus at least two and typically 20 flanking intronic nucleotides upstream and downstream of each coding exon, covering the conserved donor and acceptor splice sites, as well as typically 20 flanking nucleotides in the 5′ and 3′ UTR.

Test orders must include an attestation that the provider has the patient's informed consent for genetic testing.

Pre-authorization This test may require preauthorization from the insurance provider. Check the payer guidelines and, if needed, obtain the pre-authorization prior to sample collection.
