Kappa (4 vs ref 2mg/dl) and sometimes lambda light chain in 24hr urine without mm. what can be suspected? anemia, worsening ckd, improves with na co3

K+L chains in ua: hello, the fact that you are having this checked in your urine means that some person is already onto the fact that you may have MGUS or multiple myeloma. The worsening anemia and kidney deterioration is more indicative of myeloma. BUT you need the whole urine and blood protein electrophoresis to look at before making the diagnosis. You shd request referral to a Heme-Onc specialist to decide.thx
