Pj. Cagnoni et al., SPURIOUS FIBRINOGEN LEVELS SECONDARY TO PYROGLOBULINEMIA IN WALDENSTROMS MACROGLOBULINEMIA, American journal of hematology, 48(2), 1995, pp. 126-127
We report two cases of pyroglobulinemia detected in the course of rout
ine determination of fibrinogen levels measured by the heat-precipitat
ion method and that led to the diagnosis of Waldenstrom's macroglobuli
nemia. The incidence of pyroglobulinemia is briefly discussed, and the
potential significance of this laboratory artifact is emphasized. (C)
