The usefulness of antiserum specificity checking: an even stronger requirement in IF than in IEP.
a. Anti-bound and free lambda light chain antiserum cross-reacting with fibrinogen in IF.
T is plasma electrophoresis
b. Fibrinogen and free light chain arcs have different shapes in IEP.
Free k is for anti-free kappa light chain antiserum; free l is for anti-free lambda light chain antiserum; U means urin with monoclonal free lambda light chains.
Other symbols and abbreviations have been previously defined.
