Accuracy of microchip identification in dogs and cats.
A study was performed to determine the sensitivity and specificity of a commercially available microchip identification system approximately 1 year after implantation in dogs and cats. Thirty-three dogs and 16 cats in which a microchip had been implanted and 31 dogs and 18 cats in which a microchip had never been implanted were included in the study. In cats, sensitivity and specificity of microchip identification were 1.00. In dogs, sensitivity and specificity were 0.97 and 1.00, respectively. The chip had migrated in the 1 dog with a false-negative result, but the chip remained functional, and identification was established in this dog following closer physical examination and scanning.
