The association between bloodwork, signalment, and urolithiasis in guinea pigs (Cavia porcellus)

Urolithiasis represents a common, potentially life-threatening condition in pet guinea pigs (Cavia porcellus). The purpose of this study is to determine the potential association between signalment, packed cell volume, total solids, selected biochemical parameters, and imaging evidence of urolithiasis in client-owned guinea pigs presented to two veterinary teaching hospitals. Medical record databases from two veterinary teaching hospitals were searched for cases of client-owned guinea pigs that had both a plasma biochemistry panel and an imaging study performed during one medical event. Other parameters including age, sex, weight, packed cell volume, and total solids were also recorded.
