Because the kidneys filter these proteins out of your blood, chronic kidney disease can lead to higher levels and slightly altered ratios.
Conditions like rheumatoid arthritis or recent viral infections can temporarily increase light chain production. Abnormal Serum Light Chain Ratio

Conditions like multiple myeloma or MGUS (Monoclonal Gammopathy of Undetermined Significance) can cause one type of light chain to be overproduced, skewing the ratio. Typical Next Steps Conditions like multiple myeloma or
An indicates that the balance between two types of proteins— kappa and lambda free light chains—is outside the standard range of roughly 0.26 to 1.65 . These proteins are produced by plasma cells to help your immune system fight infections.
