A member asked:
Saw hematologist.all labs normal except serum immunofixation.showed faint igg lambda bands.no m spike.how serious? mm?or mgus likely?
A doctor has provided 1 answer
Need more info: All laboratory results need to be interpreted in the clinical context and the doctor who ordered the tests is usually in the best position to do that. Having said that, Faint IgG lambda band is more likely to be MGUS, however, other issues need to be examined, such as, what is the level of background un-involved immunoglobulins, hemoglobin level, serum calcium and creatinine levels and if need be x-ray examination of bones. Serum free light chain assay is useless for the differentiation.

This is for my mother, aged 55. High serum kappas (33), normal lambdas and marginally high kappa lambda ratio (1.9). SPEP and Immunofixation show polyclonal gammopathy (in IgG Kappa and Lambda). Should we be concerned about MGUS/Myeloma ?
I had a serum immunofixation and serum electrophoresis run and the interpretation was suspicious of monoclonal gammopathy and IgG lambda. What does this mean? The beta and gamma globulin where at 0.6 and 0.7 g/dl?
Serum free light chain test shows normal kappa (8.7mg/dl), low lambda (3.80), high kap/lam ratio (2.31). Serum $ urine electrophoresis show no monoclonal protein, nor does serum immunofixation. Likely MGUS, myeloma, or admyloidosis? CBC/met panel ok.
I took a Immunofixation serum test in December and it was negative. I took it again in January and February. The IFE interpretation says: IgG kappa monoclonal band present. A faint monoclonal free lambda light chain is detected. Do I have cancer?
I had serum immunofixation. Scared.no monoclonol proteins. But read'"faint igg. Lambda. Cannot be excluded?
