Hi my brother was diagnosed of MM Jan 2022.He is 37. He underwent 4 cycles of chemotherapy and then a stem cell transplant. The reports 90 days post ASCT showed he is in complete remission. Now it's 6 months from transplant and although he was initially diagnosed with IgA Lambda Multiple myeloma now in the recent test the kappa figures are high it's 30 while the upper limit is 19. Can someone tell me how the kappa is increasing now. No m band seen
