SHORT-TERM ASSESSMENT OF RED BLOOD CELL SURVIVAL USING 51 Cr

5 Cr techniques for the study of red blood cell survival over long periods in the steady state are now well established (Ebaugh, Emerson, and Ross, 1953; Mollison and Veall, 1955; Hughes Jones and Mollison, 1956). This paper presents the results of an investigation of the validity of a 51 Cr study not exceeding 10 days which is well suited to a combination with a 59 Fe technique for the rapid simultaneous assessment of red cell production and destruction where haematological conditions may show fairly rapid changes.
