Dear Dr. Indranil Ghosh, As per advise of doctors in medanta hospital and as suggested by you, We ve got 4th cycle of chemotherapy (Bort-Dex) completed. After which doctor prescribed for tests Serum free light chain, CFC & KFT. I ve attached the report. Please have a look. Last Serum free light chain was done 1 month back after 3rd cycle which showed Kappa\Lambda ratio to be normal (0.88). But this time after 4th cycle kappa lambda ratio is increased to 1.86. Doctor here will be putting her on maintainace after reviewing the reports. Please suggest what does the current report indicate and further course of action? Thanks, Bhuwan Grover
