|a BACKGROUND: Guinea pigs (Cavia porcellus) are often presented as patients in veterinary practice. Nevertheless, only limited information is available about endocrine diseases or thyroxine reference values for the species
|
520 |
|
|
|a OBJECTIVE: The aim of this study was to determine serum thyroxine concentrations in a well-defined population of clinically healthy pet guinea pigs
|
520 |
|
|
|a METHODS: Between October 2007 and July 2008, serum samples were collected from 40 clinically healthy guinea pigs of different sexes, ages, and breeds that were presented to our clinic for a general health check or for castration. Pregnant females were excluded from the study. Thyroxine concentration was measured using a chemiluminescence test (Immulite 2000 Canine Total T4)
|
520 |
|
|
|a RESULTS: Thyroxine concentrations ranged from 14.2 to 66.9 nmol/L (1.1-5.2 microg/dL) with a median value of 27.0 nmol/L (2.1 microg/dL). Females (n=16) had significantly (P=.039; Mann-Whitney U-test) lower thyroxine values than castrated males (n=8), whereas no differences were found between females and intact males (n=16) or between intact and castrated males. No significant correlation was found between thyroxine concentration and age
|
520 |
|
|
|a CONCLUSION: This is the first report of serum thyroxine reference values for a well-defined population of healthy pet guinea pigs as measured by a chemiluminescence assay. The results were higher than those previously reported for this species and emphasize the importance of using appropriate reference intervals for the diagnosis of hyperthyroidism
