Comparative study on the modified Costa reaction and sedimentation rate was conducted on 411 healthy persons and 1, 886 tuberculous patients who were admitted at Niigata National Sanatorium. The results were as follows:
1) Our modified Costa reaction can be performed with the residuals of the blood samples that were used for the examination of sedimentation rate, and can be carried out on a number of cases at one time.
2) The results of modified Costa reaction showed more clean correlation with clinical symptoms than that of sedimentation rate. Environmental factors influenced on the results of Costa reaction in lesser degree than in case of sedimentation rate.
3) While marked changes of sedimentation rate were frequently observed in non-tuberculous persons, modified Costa reaction showed a specific tendency of changes in subclinical tuberculous patients.
4) It was suggested that modified Costa reaction had a prognostic significance.
