NOTE: 1  It is a good idea to label each equation. 2  This value of x can be substituted into equation [1] or [2], or into the expression for y: y = 2x â 1. 3  Choose the one that is easiest!  As a check, substitute the values back into each of the two starting equations.
Paraprotein. A paraprotein is an immunoglobulin or immunoglobulin light-chain that is produced in excess by the clonal proliferation of plasma cells. Detection of paraproteins in the urine or blood is most often associated with benign MGUS, where they remain silent, and multiple myeloma.araprotein.

Raised serum globulin concentration or total protein may be the first indication of a paraprotein, but a raised globulin level is more commonly due to polyclonally raised globulins in reaction to inflammation, infection, or cancer.efinition of the immunoglobulin class of the paraprotein by immunofixation (immunoglobulin heavy and light chain isotype). This is important as the type may direct future investigations. Myeloma is commonly associated with an IgG or IgA paraprotein, rarely IgD or IgE (see fig 2 â).
