Multiple myeloma patients had significantly reduced haemoglobin (9.3 ± 2.4 g/dL in MM vs 12.8 ± 1.97 g/dL in healthy controls; p = 0.045) and serum albumin (2.46 ± 0.9 g/dL in MM patients vs 4.63 ± 1.1 g/dL in healthy controls; p < 0.0001) when compared to healthy controls. Here, ALB is linked to AL amyloidosis.
