LOINC long common name : HBG1 and HBG2 genes full mutation analysis in Blood or Tissue by Sequencing;
LOINC short name : HBG1 HBG2 Full Mut Anl Bld/T Seq;
LOINC description : Full gene sequence analysis of the gamma globin genes, HBG1 and HBG2, is performed
to assess for variants causing conditions such as neonatal hemolytic anemia, cyanosis,
methemoglobinemia, and nondeletional hereditary persistence of fetal hemoglobin (HPFH).
Testing is useful to characterize abnormal hemoglobins identified by electrophoresis
and suspected to be due to gamma chain variants. This code is used for the test order
and to represent the overall report, which may include the variant(s) found, testing
method, interpretation, recommendations and references.;
