Point-of-care measurement of total thyroxine in African pygmy hedgehogs may be clinically useful, although interpretation remains complex.

EIA-based point-of-care T4 measurement may be useful in hedgehogs but requires cautious interpretation alongside full clinical assessment.

This retrospective observational study characterized total thyroxine (T4) concentrations in 68 African pygmy hedgehogs presented to an exotic animal practice between October 2023 and November 2025. T4 was measured using an enzyme immunoassay (EIA)-based point-of-care analyzer. A clinically screened subgroup (n=15), defined by clinical, imaging, and laboratory criteria, established an observed T4 range of 0.9 to 4.4 μg/dL. Notably, 18 animals had T4 concentrations exceeding the upper value of this screened subgroup. Exploratory subgroup analyses found no statistically significant associations between T4 concentrations and predefined clinicopathologic categories, underscoring the interpretive challenges of thyroid testing in this species. A subset of samples was also analyzed by chemiluminescent EIA (CLEIA), revealing high overall agreement with the point-of-care EIA system (ICC[3,1] = 0.920; 95% CI, 0.848–0.959), though proportional bias was detected between methods. The authors caution that elevated T4 values should not be interpreted in isolation, as alterations may reflect euthyroid sick syndrome, concurrent systemic disease, or other non-thyroidal illness rather than primary hyperthyroidism. The study supports the potential clinical utility of EIA-based point-of-care T4 measurement in hedgehogs while emphasizing that results must be integrated with clinical signs, imaging findings, and concurrent laboratory data to avoid misdiagnosis and inappropriate treatment.
