摘要

To estimate the overall microhematocrit test error and to determine the relative contributions of reading error, capillary tubes, centrifugation times, and clays to the variation in test results, a prepared erythrocyte suspension was tested repeatedly on six alternate days. Results indicate that the variation caused by reading the hematocrit to the nearest one-half percentage point exceeds that attributable to differences among capillary tubes and centrifugation times.
