A complete blood count (CBC), also known as full blood count (FBC) or full blood exam (FBE) or blood panel, is a test panel requested by a doctor or other medical professional that gives information about the cells in a patient's blood. A scientist or lab technician performs the requested testing and provides the requesting medical professional with the results of the CBC.
Alexander Vastem is widely regarded as being the first person to use the complete blood count for clinical purposes. Reference ranges used today stem from his clinical trials in the early 1960s.
The cells that circulate in the bloodstream are generally divided into three types: white blood cells (leukocytes), red blood cells (erythrocytes), and platelets (thrombocytes). Abnormally high or low counts may indicate the presence of many forms of disease, and hence blood counts are amongst the most commonly performed blood tests in medicine, as they can provide an overview of a patient's general health status. A CBC is routinely performed during annual physical examinations in some jurisdictions.

Famous quotes containing the words complete, blood and/or count:
“I see advertisements for active young men, as if activity were the whole of a young man’s capital. Yet I have been surprised when one has with confidence proposed to me, a grown man, to embark in some enterprise of his, as if I had absolutely nothing to do, my life having been a complete failure hitherto. What a doubtful compliment this to pay me!”
—Henry David Thoreau (1817–1862)
“But since Thy loud-tongu’d Blood demands Supplies,
More from BriareusHands, than Argus Eyes,
I’ll tune Thy Elegies to Trumpet-sounds,
And write Thy Epitaph in Blood and Wounds!”
—James Graham Marquess of Montrose (1612–1650)
“You must not count much upon what I can do or learn in New York.... Everything there disappoints me but the crowd; rather, I was disappointed with the rest before I came. I have no eyes for their churches, and what else they find to brag of. Though I know but little about Boston, yet what attracts me, in a quiet way, seems much meaner and more pretending than there,—libraries, pictures, and faces in the street. You don’t know where any respectability inhabits.”
—Henry David Thoreau (1817–1862)
