RBC counts per minute (CPM) were reported at various times of blood collection (mean ± SEM of triplicate assays). The percentage of cRBC survival was calculated by dividing the number of CPM at various times by the CPM obtained at day 0 and subsequently corrected for k values. Coefficient of elution of chromium is shown in percentage per day.
