While the reported warfarin f u values range from 0.005 to 0.022 in human plasma, more than a 4-fold difference, the absolute difference is low. The majority of references indicate a narrower range, therefore the acceptable assay f u value for warfarin should be within 0.005 to 0.015, a range similar to that reported in the recently published
Minimum Volume. 1 mL plasma or serum. Additional Information. Note that whole blood is recommended as the optimum specimen type for Vitamin B1 (thiamine) analysis because the biologically active form of thiamine is found in erythrocytes in the form of thiamin diphosphate (TDP), which is found in very low concentrations in plasma or serum.

difference between involved and uninvolved FLC levels is required in place of the M-protein criteria If serum and urine M-protein are not measurable, and serum free light assay is also not measureable, ≥ 50% reduction in plasma cells is required in place of M-protein, provided baseline bone marrow plasma cell percentage was ≥ 30%

Formed elements and plasma. Both are portions of whole blood. Plasma is the liquid portion which makes up 55%. It includes water, cells and cell fragments and other. Plasma = Serum + clotting factors. Formed elements are leukocytes, platelets and erythrocytes. Makes up 45% of while blood. Compare and contrast. Erythrocyte and leukocyte.
Plasma is the fluid portion of blood that contains proteins, ions, nutrients, hormones, antibodies, metabolites, enzymes, clotting factors, etc. Plasma is straw-colored and makes up approximately 55% of whole blood volume. The formed elements of blood are the red blood cells ( erythrocytes ), white blood cells ( leukocytes ), and platelets Serum and plasma are obtained from the liquid portion of the blood that is obtained when the cells are removed. However, there is striking difference between plasma and serum. Serum is the liquid that remains after the clotting of blood. Whereas, plasma is the liquid that remains when anticoagulant is added to prevent clotting. . 319 379 214 288 19 256 369 199 230
