Certain basic lab tests are performed right in our clinic. This includes things such as testing stool and urine samples, and some blood tests. In some cases, we use selected outside veterinary laboratories. Some of the tests conducted are similar to those available in the clinic, but the availability of advanced testing equipment in a specialized facility may offer advantages in speed and accuracy. For example, the specialized laboratory may be able to more easily spot and identify abnormally shaped red or white blood cells, both of which can help confirm a disease diagnosis, during routine tests on a blood sample. At an outside laboratory, specialized tests may be performed, such as one to detect larval stages of parasites that are not easily found on standard tests. Because parasites also occur in samples other than stool samples, a direct smear of a pet’s blood on a slide can be analyzed to detect the presence of blood parasites.
