There is minimal knowledge known on the analyte breakdown of this or closely related species. As this species becomes more popular in the exotic community more medical conditions are being identified that can be assisted in diagnosis with the establishment of ranges of the different essential analytes. Being an insectivorous lizard, this species may suffer from hypovitaminosis A. There has been a lack of antemortem diagnostics available for minimally invasive and appropriate diagnosis of this disease. Recent studies have been performed in other small insectivore species establishing plasma retinol reference intervals. Reference intervals for retinol have not been published or validated in collared lizards or any closely related species.</div></div><div><h3>Methods</h3><div>Plasma, with a sample volume of only 50 µl, from forty clinically healthy captive bred Eastern collared lizards, twenty males and twenty females were analyzed using ultra-high-performance liquid chromatography with tandem mass spectrometry (UPLC-MS/MS) to determine plasma retinol concentrations.</div></div><div><h3>Results</h3><div>Using UPLC-MS/MS analysis, data was normally distributed and a reference interval for plasma retinol in the Eastern collared lizard was 1.57-3.07 µg/mL (0.237-0.464 µmol/L).
