Final answer:
A VetCo Partner generally advises pet parents to return the fecal sample to the next clinic which is true; proper instructions are vital for fecal test accuracy involving a microscopic examination and serologic testing.
Step-by-step explanation:
The statement about a VetCo Partner advising the pet parent to bring a stool sample back to the next clinic after purchasing a fecal test kit would generally be considered true. Fecal test kits typically require a fresh sample to be submitted for analysis, and providing instructions for sample collection and submission is part of ensuring proper testing procedures are followed. When a fecal test is needed, a pet parent is generally given a test card and advised to collect a patient serum sample, which is then tested using a reagent, such as a suspension of horse erythrocytes. Moreover, a microscopic examination of stool over a period of days and some serologic tests may be conducted to diagnose the health status of the pet accurately.
