A member asked:
Is elevated kappa/lambda ratio on serum flc test inherently monoclonal, even if neither kappa or lambda is elevated? ratio high b/c lambda is low, not because of high kappa. spep/upep & ife normal. high iga, low igg. clean marrow biopsy. polyclonal?

FLC not useful: FLC and kappa/lambda ratio are not useful tests. A normal K/L ratio does not exclude monoclonal gammopathy and an abnormal one is not diagnostic of one. From what you described you do not have monoclonal gammopathy and certainly have no multiple myeloma.

Clinical context : The use of light chains is limited in diseases other than monoclonal gammopathies, such as myeloma or amyloidosis. If this is the context that yours got checked the results do not suggest such a condition. With no gammopathy suggested by results the question regarding clonality has no grounds. As any other test, trending the results would help in integrating it in a meaningful clinical context.

Gave plasma, leading to tests (cbc, SPEP, immunofixation, FLC). Waiting for hemo consult. Have high IGA (7.09g/l) but low IGG (3.05) &low IGM(.15). Monoclonal IGA type lambda found (8.5mg/l), lambda=33.4mg/l, but LC ratio ok. Am I immune compromised?
High IGA (7.09 g/l), and low IGG (3.05) and low IGM (.15). Beta1 globulin is high, beta2 and gamma are low. Protein Monoclonal band is detected type IGA at 8.5 g/l. FLC = high lambda at 33.4mg/l (normal kappa &ratio). Worried until I see hematologist?
