Objective-To provide values for gastrointestinal permeability and absorptive function tests (GIPFTs) with chromium 51 ((51)Cr)-labeled EDTA, lactulose, rhamnose, d-xylose, 3-O-methyl-d-glucose, and sucrose in Beagles and to evaluate potential correlations between markers. Animals-19 healthy adult male Beagles. Procedures-A test solution containing 3.7 MBq of (51)Cr-labeled EDTA, 2 g of lactulose, 2 g of rhamnose, 2 g of d-xylose, 1 g of 3-O-methyl-d-glucose, and 8 g of sucrose was administered intragastrically to each dog. Urinary recovery of each probe was determined 6 hours after administration. Results-Mean ± SD (range) percentage urinary recovery was 6.3 ± 1.6% (4.3% to 9.7%) for (51)Cr-labeled EDTA, 3.3 ± 1.1% (1.7% to 5.3%) for lactulose, 25.5 ± 5.0% (16.7% to 36.9%) for rhamnose, and 58.8% ± 11.0% (40.1% to 87.8%) for 3-O-methyl-d-glucose. Mean (range) recovery ratio was 0.25 ± 0.06 (0.17 to 0.37) for (51)Cr-labeled EDTA to rhamnose, 0.13 ± 0.04 (0.08 to 0.23) for lactulose to rhamnose, and 0.73 ± 0.09 (0.60 to 0.90) for d-xylose to 3-O-methyl-d-glucose. Median (range) percentage urinary recovery was 40.3% (31.6% to 62.7%) for d-xylose and 0% (0% to 0.8%) for sucrose. Conclusions and Clinical Relevance-Reference values in healthy adult male Beagles for 6 of the most commonly used GIPFT markers were determined. The correlation between results for (51)Cr-labeled EDTA and lactulose was not as prominent as that reported for humans and cats; thus, investigators should be cautious in the use and interpretation of GIPFTs performed with sugar probes in dogs with suspected intestinal dysbiosis.
