What are the differences between SPEP, UPEP, free serum light chains, and serum/urine immunofixation?
Monoclonal protein can be a complete immunoglobulin with a heavy chain (IgG, IgA, IgD, or IgM) complexed with a light chain (kappa or lambda), or free light chains without a heavy chain component
SPEP & UPEP can quantify the presence of a monoclonal protein but cannot identify the subtype of immunoglobuiln, and may miss small M proteins
Serum FLC testing detects light chains that are not bound to heavy chains, and can quantify them
Serum/urine immunofixation can subtype the immunoglobulin and differentiate monoclonal vs. polyclonal spike
