What This Test Measures
Electrophoresis separates hemoglobin molecules based on their electrical charge. This qualitative test detects variations in hemoglobin types, such as normal hemoglobin A, abnormal hemoglobin S (common in sickle cell disease), or other variants.
Why It’s Done
Your doctor may order this test if you have symptoms like fatigue, pain, or frequent infections, or if you have a family history of hemoglobin disorders. It can also be used to screen newborns for conditions like sickle cell disease.
Sample Collection and Preparation
A blood sample is drawn from a vein, usually in your arm. The blood is then processed to separate the hemoglobin components for analysis.
What to Expect Before the Test
No special preparation is needed, but inform your healthcare provider about any medications or supplements you’re taking, as they may affect results.
Reference range
Adult males: 13.5-17.5 g/dL; Females: 12.0-16.0 g/dLN/A
No special preparation usually required. Stay well hydrated. Inform your healthcare provider of all medications and supplements you are taking.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
Abnormal hemoglobin patterns can indicate inherited blood disorders like sickle cell disease, thalassemia, or other hemoglobinopathies. These conditions can cause chronic anemia, pain, or complications like organ damage. Early detection helps manage symptoms and prevent complications.
