Blood chemistry analysis is commonly performed to evaluate function of which gland in an animal showing lethargy, obesity, mild anemia, infertility, and alopecia?

• A. Adrenal glands
• B. Thyroid gland
• C. Pancreas
• D. Thymus

Answer: (B)

Blood chemistry panels are used to screen how endocrine organs are functioning, particularly the thyroid, which plays a key role in regulating metabolism. The combination of lethargy, obesity, alopecia, and sometimes mild anemia or reproductive changes is a classic pattern seen with hypothyroidism, where thyroid hormone levels are low and metabolic rate slows. Since the thyroid gland governs metabolic activity, evaluating its function is the most appropriate use of a blood chemistry study in an animal with these signs. The other glands have different typical patterns: adrenal disorders produce distinct skin and energy changes often linked to cortisol imbalances, pancreatic issues center on glucose regulation and weight loss rather than weight gain with alopecia, and the thymus does not feature prominently in standard blood chemistry for these clinical signs.
