Which laboratory tests are commonly included in a senior dog's health screening?

• A. Rabies titer alone.
• B. Urinalysis and CBC are all that's needed.
• C. MRI of the brain is standard for all seniors.
• D. Blood chemistry panel, complete blood count, urinalysis, and sometimes thyroid tests or kidney function tests.

Answer: (D)

A broad panel of tests that checks the major organ systems gives the best picture of a senior dog's health. This commonly includes a complete blood count to look for anemia, infection, or inflammation; a blood chemistry panel to assess liver and kidney function, electrolyte balance, glucose, proteins, and other metabolic markers; and a urinalysis to evaluate kidney function, urinary tract health, and metabolic status. Depending on the dog’s risk factors or symptoms, thyroid testing or additional kidney function measures may be added. This combination provides a comprehensive snapshot and helps catch issues early, whereas relying on a rabies titer alone isn’t a general health screen, focusing only on vaccination status. MRI of the brain is an advanced test used when neurological signs are present, not a routine screening for all seniors.
