The erythrocyte sedimentation rate (ESR or sed rate) is the rate at which red blood cells in anticoagulated whole blood descend in a standardized tube over a period of one hour. It is a common hematology test, and is a non-specific measure of inflammation .
Whole blood: CBC, ESR, Coombs test, platelet antibodies, flow cytometry, blood levels of tacrolimus and cyclosporin: Pink K 2 EDTA (chelator / anticoagulant) Blood typing and cross-matching, direct Coombs test, HIV viral load Royal blue ("navy") EDTA (chelator / anticoagulant) Trace elements, heavy metals, most drug levels, toxicology: Tan

Histopathology: used to make blocks of tissue for cutting into thin slices for microscopy Block holders (in ...
Variety of microbiological samples. A laboratory specimen is sometimes a biological specimen of a medical patient's tissue, fluids, or other samples used for laboratory analysis to assist in differential diagnosis or staging of a disease process. These specimens are often the most reliable method of diagnosis, depending on the ailment.
Composing less than 1% of the total volume of the blood sample, the buffy coat (so-called because it is usually buff in hue), contains most of the leukocytes and thrombocytes. [ 2 ] [ 3 ] The buffy coat is usually whitish in color, but is sometimes green if the blood sample contains large amounts of neutrophils , which are high in green-colored ...
A blood test is a laboratory analysis performed on a blood sample that is usually extracted from a vein in the arm using a hypodermic needle, or via fingerprick. Multiple tests for specific blood components, such as a glucose test or a cholesterol test , are often grouped together into one test panel called a blood panel or blood work .
It correlates with the erythrocyte sedimentation rate (ESR), however not always directly. This is due to the ESR being largely dependent on the elevation of fibrinogen, an acute phase reactant with a half-life of approximately one week. This protein will therefore remain higher for longer despite the removal of the inflammatory stimuli.
The history of discrete sample analysis for the clinical laboratory began with the introduction of the "Robot Chemist" invented by Hans Baruch and introduced commercially in 1959 [1]. The AutoAnalyzer is an early example of an automated chemistry analyzer using a special flow technique named "continuous flow analysis (CFA)", invented in 1957 by ...
