Coagulation tests would be useful for diagnosing which condition?

• A. Thyroid function
• B. Rodenticide poisoning
• C. Adrenal function
• D. Ethylene glycol poisoning

Answer: (B)

Coagulation tests measure how well the blood clots, revealing abnormalities in the clotting cascade. In veterinary practice, ingestion of anticoagulant rodenticides is a classic cause of coagulopathy because these poisons disrupt vitamin K–dependent clotting factors, leading to longer clotting times such as PT and aPTT. This makes coagulation testing particularly useful for diagnosing rodenticide poisoning, since the primary issue is impaired clotting rather than endocrine or toxic effects on other organ systems. The other options—thyroid, adrenal, or ethylene glycol poisoning—primarily affect metabolic or organ function in ways that aren’t detected by coagulation tests, so they’re not as directly indicated by coagulation screening.
