Hemoglobin Electrophoresis Evaluation, Blood
Use
This test is useful for the diagnosis and classification of hemoglobin disorders, including thalassemias and hemoglobin variants. Hemoglobin electrophoresis is a critical component in identifying abnormal hemoglobin variants that can lead to clinical conditions such as thalassemias and sickling disorders.
Special Instructions
It is recommended to include recent transfusion information and the most recent complete blood cell count results when ordering this test. Additionally, if monitoring treatment with HbA-T87Q (Lyfgenia for sickle cell disorders or Zynteglo for thalassemia), complete Metabolic Hematology Patient Information to notify the laboratory and request mass spectrometry testing.
Limitations
Some hemoglobin variants and thalassemia conditions are not detectable by routine screening methods and may require molecular testing for accurate identification. Recent transfusions can affect results, particularly in hemoglobin electrophoresis and other stability or solubility studies. Proper communication of the patient's clinical history and prior therapies is essential for selecting the appropriate reflex tests.
