| Densitometer Tracings A densitometer tracing of the hemoglobin electrophoresis gel is made in order to quantitate the bands present. Below is a normal gel and its corresponding tracing. Hemoglobin A is 98% and A2 is 1.5%. Notice that Hemoglobin F is usually present in small enough amounts that its tracing may blend into that of Hemoglobin A. A separate procedure may need to be performed if quantitation of HbF is important. | View Page |
| Normal Hemoglobin Electrophoresis Densitometer Tracing This densitometer tracing corresponds to the pattern for normal distribution of hemoglobin. | View Page |
| Hemoglobin electrophoresis on this patient's sample is pictured above and is labeled "patient 2" in lanes 5 and 6. The densitometer tracing of lane 5 is also pictured.What hemoglobin bands are present? | View Page |
