Validation of the Accuracy of Automatic Measurement of Blood Volume in Culture Bottles for Blood Culture

Several manufacturers have developed systems that automatically measure the amount of blood in culture bottles. We compared volumes measured by Virtuo instrument (bioMérieux, France) (height-based volumes) and those calculated weighing In all, 150 pairs aerobic anaerobic bottles (BacT/ALERT FA/FN Plus, bioMérieux) were randomly selected over two periods to compare height- weight-based analyze effect foam. also estimated limit detection (LOD) cut-off value for 5 mL equine blood. The mean height-based volume was approximately 0.67 greater than volume, particularly Foam did not a significant effect. LOD automatic 0.2–0.4 mL. 4–4.2 Therefore, when reporting or monitoring within laboratory, these performance characteristics should be adequately considered.
