LOINC description : Plasma and serum viscosity measurements are used in the clinical management of patients
with hyperviscosity syndrome, which is caused by a variety of clinical diagnoses,
such as polycythemia, Waldenström macroglobulinemia, multiple myeloma, and occasional
cases of rheumatoid arthritis, SLE, systemic lupus erythematosus, hyperfibrinogenemia
and leukemia. Common symptoms of hyperviscosity are, bleeding, visual signs or symptoms,
and neurologic deficits. The viscosity at which symptoms develop is variable, but
they rarely appear below a serum or plasma viscosity of 3 cP. Viscosity can be reported
qualitatively or quantitatively. Commonly, quantitative units are defined as rel to
H2O, and are expressed in centipoise (cP).[PMID: 16830959] Whole blood viscosity is
increased in polycythemia, rouleau formation, and other conditions listed for serum
and plasma, but may be of limited clinical value because of the differences in shear
rates between the instrument and in vivo conditions.[Tietz];
