To develop a method for the early diagnosis of health damage due to arc welding, we measured serum ferritin in 96 general employees and 320 arc welders in Company A. A positive correlation was observed between age and the serum ferritin level in the young group age, 20 - 44 years among the general employees. The mean serum ferritin level in the general employees was 119 ± 56 ng-ml. When the mean ± 2.5 SD was used as the standard value, ferritin levels > 260 ng - ml could be regarded as high. Based on this standard value, high ferritin levels were observed in 7 6.6% of 106 young arc welders in Company A but none of the general employees. Chest X-ray films showed minimal abnormality in one of 7 young arc welders who showed high ferritin levels. These results suggest that the determination of the serum ferritin level is useful for the early diagnosis of health damage due to arc welding.
