serial analyses of f reticulocytes and nonreticulocyte f cells ( f erythrocytes ) illustrate that ( 1 ) levels of f reticulocytes and f erythrocytes are persistently similar in normal adults with more than 6 % f cells and thus cell survival times of f and non-f cells must be essentially the same , ( 2 ) changing levels of f reticulocytes can be sensitive predictors of later changes in mature f cell frequencies during infancy and in adults recovering from aplastic anemia , and ( 3 ) alterations in f reticulocyte frequency and the amount of hbf per f reticulocyte are discordant in some settings but concordant in others .
