| name | Viscosity of Serum | ||
| 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 is reported in units 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] | ||

| property | Visc = Viscosity | ||
| time | Pt = Point in time: To identify measures at a point in time. This is a synonym for “spot” or “random” as applied to urine measurements. | ||
| system | Ser = Serum | ||
| scale | Qn = Quantitative: The result of the test is a numeric value that relates to a continuous numeric scale. Reported either as an integer, a ratio, a real number, or a range. The test result value may optionally contain a relational operator from the set {<=, <, >, >=}. Valid values for a quantitative test are of the form "7", "-7", "7.4", "-7.4", "7.8912", "0.125", "<10", "<10.15", ">12000", 1-10, 1:256 | ||
