Test ID WGSQR Gamma-Globin Full Gene Sequencing, Varies


Specimen Required


Only orderable as a reflex. For more information see:

-HAEVP / Hemolytic Anemia Evaluation

-HBELC / Hemoglobin Electrophoresis Cascade, Blood

-MEVP / Methemoglobinemia Evaluation

-REVE / Erythrocytosis Evaluation

THEVP / Thalassemia and Hemoglobinopathy Evaluation


Useful For

Evaluates for the following in an algorithmic process for the HAEVP / Hemolytic Anemia Evaluation; HBELC / Hemoglobin Electrophoresis Cascade, Blood; MEVP / Methemoglobinemia Evaluation; REVE / Erythrocytosis Evaluation; THEVP / Thalassemia and Hemoglobinopathy Evaluation:

-Evaluation for suspected gamma variants or nondeletional hereditary persistence of fetal hemoglobin (HPFH)

 

Assess for unstable gamma chain variants (there are occasionally newborns who are jaundiced at birth, often requiring phototherapy, in which all other tests for causes of hemolysis are unrevealing)
