Do (serum) kappa and lambda light chains fluctuate in a healthy person, sometimes going outside of the normal range very slightly? As long as the k/l ratio is normal and all other bloodwork including check for M proteins negative, should I not worry?
What is the significance of having low serum levels of kappa and lambda free light chains? I had high ch50 and normal C3 and c4.
Question about lab results from hematologist. Free kappa light chains serum 19.97 (range is 3.30-19.40mg/l) Normal lambda and ratio.
Had labs done and my Kappa Free levels are 2.49 mg/dL , Lambda Free levels are 1.50 mg/Dl and my ratio is 1.66. Labs showed no serum monoclonal protein and other proteins Alpha1/2,A1,A2,Beta,Gamma came back normal. Should I be concerned?
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
