Examination of serum ferritin and erythrocyte ferritin--its role in the blood transfusion service.
Blood donors were examined for serum ferritin values and concentration of ferritin in the erythrocytes. The group of male and female donors without previous donations showed average values of 102.27 ng and 51.75 ng of ferritin per one ml of serum, respectively. Males with over 20 donations had 68.04 ng ferritin per one ml, females 37.14 ng of ferritin per one ml. The reduced serum ferritin values in multiple male and female donors is statistically significant. Serum ferritin values in women of the two groups are lower than those of males, the difference also being statistically significant. In male and female blood donors, irrespective of the number of donations, average values of 13.74 ag and 12.07 ag of ferritin per erythrocyte, respectively, were established. The difference in ferritin concentration in the erythrocytes between males and females is statistically insignificant. The correlation coefficient failed to demonstrate any dependence between erythrocyte ferritin concentration and concentration of ferritin in the serum. The object of serum ferritin determination in blood donors is to detect the earliest stage of storage iron deficiency in the organism. For the latter purpose, the determination of erythrocyte ferritin is ineffective.
