The: Concern would be low ch50 and low C3 ; c4, like in lupus. Elevations in kappa or lambda would be of concern for myeloma, not to worry about these levels.

I have normal levels of complement C2 and c4. C3 level is low. Ch50 is high-normal(57 u/ml)-(all are serum tests)-what are the possible causes?

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.

Kappa/lambda FLC ratio high (2.75) w/ normal K(10.21mg/dl) & low L(3.68mg/dl). Hem-onc unsure if ratio implies K monoclonality since serum/urine IFE ok & neither chain is elevated. Could monoclonal K be suppressing L? IgA a bit high IgG &IgM a bitlow

I am 45 and male. Serum IgA at 472 mg/dl and an apparent polyclonal gammopathy IgA kappa/lambda typing appear increased. Serum free light chain: high kappa 35 mg/L, lambda normal 17.8 mg/L and a ratio of 1.97. Is this Myeloma? No M-protein found?

Will drinking a lot of water each day (96+oz) decrease kappa light chain levels? Electrophoresis normal with the exception of slightly elevated kappa in serum of 21.8 (normal in urine). Normal kappa lambda ratio?
