The Egyptian fruit-bat (Rousettus aegyptiacus) has been studied in both field and laboratory settings. As bats are expected to encounter diseases potentially affecting their blood urea nitrogen (BUN) concentrations, it may be beneficial to use a rapid and accurate test for determining BUN, which can indicate azotemia and guide appropriate therapy. This study has evaluated the feasibility of commercial reagent tests strips to estimate whole-blood BUN concentration in Egyptian fruit bats. For each blood sample, the BUN strip result was compared to a predetermined color scale provided by the manufacturer, and compared to the BUN as measured by a point-of-care (POC) chemistry analyzer. There was a 100% agreement between the reagent test strip and the biochemistry analyzer’s BUN results. However, the naturally occurring low BUN of this species precluded an indication for azotemia as all tested bats were assigned to a single predetermined category. Continued investigation into alternative point of care testing in bats is warranted. Standard biochemistry analyzer should still be considered the most accurate method of BUN testing and identifying azotemia in Egyptian fruit bats.
