Clinical chemistry is the most basic area of in vitro diagnostics it is concerned with detecting the pathologic indications in bodily fluids. Chemical tests for various parts of blood and urine were developed in the 19th century. Today more sophisticated techniques, including the measurement of enzyme activity, spectrophotometry, and the location of specific antigens. Clinical chemistry rarely involves a human operator performing the test by hand; most current laboratories are now completely or partially automated and use monitored and quality – tested assays. Common test types in clinical chemistry are serum and plasma. Serum is the yellow watery part of blood that is left after blood has been allowed to clot and all blood cells have been removed. This is most easily done by centrifugation which packs the denser blood cells and platelets to the bottom of the centrifuge tube, leaving the liquid serum fraction resting above the packed cells. Plasma is serum before clotting, so that it contains clotting factors; for instance fibrinogen.
