Hemoglobin Electrophoresis (Isoelectric Focusing)
General Information
- Lab Name
- Hb Elect._Isoelectric Focusing
- Lab Code
- HBELEC
- Epic Name
- Hemoglobin Electrophoresis (Isoelectric Focusing)
- Description
Hemoglobin electrophoresis alone is not adequate for diagnosing thalassemia. Electrophoresis is limited to identification without fractionation, quantification or interpretation. This test is useful for screening for sickle cell trait for athletes other than those on UW teams. For most red cell disorders, we suggest instead ordering "Hb Disorder Thalassemia Reflex Pnl w/CBC" [HBTHLI]. If a CBC was performed within 30 days, order "Hb Disorder Thalassemia Reflexive Panel" [HBTHAL]. Both panels include hb electrophoresis, reflexive testing for thalassemia and an interpretation.
