I am now at D+90 after my ASCT. I just had monoclonal serum and free light chains tests. The monoclonal gammopathy test came back with “Serum IFE negative for monoclonal proteins” , which I assume means that there were no monoclonal proteins detected, aka no M spike, right? The serum free light chains test showed very low free kappa and very low free lambda numbers, both below normal. I have IgG kappa myeloma, so low free chain kappa should be a good thing, right? What about low free chain lambda? Are these expected results soon after ASCT? K/L ratio was not calculated due to low free light chains concentration. What is your experience with this type of results after ASCT?
