Monoclonal protein studies.

Date	Total protein, g/L (RR 60–80)	Albumin, g/L (RR 35–50)	Monoclonal band 1, g/L	Monoclonal band 2, g/L	IgG, g/L (RR 7–16)	IgA, g/L (RR 0.7–4.0)	IgM (RR 0.4–2.3)
Case 1
At diagnosis	60	33	2.8 (type: y-heavy chain in the alpha region)	18.5 (y-heavy chain in the beta region)	38.7	0.19	0.26
3 months following diagnosis	63	33	3.21	21.17	39.7	0.15	0.24
Case 2
At time 0	78	39	11.0 (IgMK)		11.6	0.8
At 10-year follow-up, after several treatments	76	40	10.7 (IgMK)	17.8 (γ-heavy chain)	35.1	0.06

Case 2: records on the patient date back to time = 0 after chemotherapy.
