<prompt> Answer this question truthfullyCould you please explain what anemia of chronic disease is?  <response>: <reason> The word hematology, which appears to have been first used in this country in 1811, is older than might be expected, for in 1743, Thomas Schwencke 1694-1768 wrote Hamatologia, sive Sanguinis Historia, Experimentis passim superstructa etc. Hagae Comitum. Hematology, like bacteriology, has developed as the result of laboratory methods and the applications of physics and chemistry.
