Hemoglobin Electrophoresis : 1000459
Test CodeHGBE or 1000459
Alias/See Also
HBE; A2 Hemoglobin; Hemoglobin A2; Sickling Test; Hemoglobin Identification
CPT Codes
83020
Includes
If hemoglobin S is present, the hemoglobin S solubility screen will be performed at an additional charge (CPT code: 85660). If hemoglobin C is present or if hemoglobin S is > 50% present, then acid hemoglobin electrophoresis will be performed at an additional charge (CPT code: 82664). If unusual hemoglobin variants are suspected, specimen will be sent out for confirmation at an additional charge. (CPT codes: 83020, 85014 ,85018, 85041).

Clinical Significance
This test is useful for diagnosis and follow-up of hemoglobin variants and thalassemias. Reflexive testing, performed at additional charge, may include hemoglobin S solubility screen and/or acid hemoglobin electrophoresis. If unusual hemoglobin variants are suspected, specimen will be sent out for confirmation.
