In order to ascertain the influence of inclination of tube upon erythrocyte sedimentation rate (ESR for short) in domestic animals, the variation rate with the change of tube inclina tion were calculated at the range of 0°-5°slope to vertical; Slope variation rate=ESR at 5° slope to vertical-ESR at the vertical position/5 (unit in mm) The results obtained are shown in Fig. 1. The slope variation rate increased to maximum value and then decreased. The correlation between the erythrocyte sedimentation types and the slope variation rate was shown in Fig. 2. The appearance of the maximum point delayed by the sedimentation types moved from acceleration types to retardation types (Table 1). The change of the slope variation rate seemed to be in close connection with the erythrocyte sedimentation types. Moreover, the variation ratio with the change of the tube inclination were calculated; Slope variation ratio=Slope variation rate/Average ESR. at the vertical position×100(%) The results obtained are shown in Table 2 and Fig. 3. The influence of the tube inclination upon the erythrocyte sedimentation in domestic animals were so great that the sedimentation rate should be measured at the exact vertical position.
