what percentage of blood is made up of plasma?
about 55 %
about 55% of blood is blood plasma, a fluid that is the blood's liquid medium, which by itself is straw-yellow in color. the blood plasma volume totals of 2.7–3.0 liters (2.8–3.2 quarts) in an average human. it is essentially an aqueous solution containing 92% water, 8% blood plasma proteins, and trace amounts of other materials. plasma circulates dissolved nutrients, such as glucose, amino acids, and fatty acids (dissolved in the blood or bound to plasma proteins), and removes waste products, such as carbon dioxide, urea, and lactic acid.

plasma cell leukemia is a form of multiple myeloma in which significant numbers of typically immature appearing plasma cells, i.e. plasmablasts, circulate in the blood. very small numbers of plasma cells may reach the circulation in non-igm multiple myeloma, non-igm smm, and, exceptionally, non-igm mgus. in these plasma cell dyscrasias, the presence of even very small numbers of circulating plasma cells is a poor prognostic indicator. in plasma cell leukemia, however, circulating plasma cells reach far higher numbers and at these circulating levels are associated with exceptionally poor survival rates. the international myeloma working group has defined the diagnostic criteria for plasma cell leukemia as the presence in blood of 2x10 plasma cells per liter or, alternatively, 20% of nucleated blood cells being plasma cells. more recently, the group has suggested that values of 0.5x10 or 5%, respectively, may be more appropriate from a therapeutic viewpoint and therefore should be studied as a definitive criterion for the disease. a recent study supported this suggestion in finding that multiple myeloma patients with 5% circulating plasma cells had a prognosis much worse than that for multiple myeloma and similar to that for plasma cell leukemia. flow cytometry immunophenotyping of blood cells to detect clonal phenotypes of plasma cells seen in multiple myeloma (e.g. the cd138, cd38, cd19, cd4 phenotype) may be a more sensitive method to enumerate circulating clonal plasma cells and diagnose plasma cell leukemia.
