Normal results for serum IFE include

Question

Quizplus · Accepted Answer

Normal results for serum Immunofixation Electrophoresis (IFE) can vary among individuals, but generally, there is no specific pattern such as a consistently darker or lighter lane for any of the immunoglobulins (IgG, IgA, IgM) or light chains (kappa, lambda) that indicates a normal or abnormal result. The presence, absence, or intensity of bands in IFE results must be interpreted in the context of the clinical picture and other laboratory findings. The choices provided do not accurately describe normal IFE results, as normal results typically show a balanced presence of immunoglobulins and light chains without the absence or disproportionate darkness/lightness of any specific component. Therefore, the statement that all the provided options (darker IgG lane, lighter IgA lane, absent IgM lane, darker kappa lane compared to lambda lane) are normal is incorrect, as these descriptions do not accurately reflect the expected balance in a normal serum IFE.
