Analyses of Free Light Chains,particularly Immunoassays That Measure the Ratio $\kappa$

Analyses of free light chains,particularly immunoassays that measure the ratio of free $\kappa$ - to free $\lambda$ -light chains,are sensitive indicators of:

A) disorders of immunoglobulin synthesis such as multiple myeloma.
B) albumin increase such as that observed in dehydration.
C) . $\beta$ -globulin disorders such as decreased LDL.
D) increased C-reactive protein such as that observed following myocardial infarction.
