If laminitis is suspected in a horse, which diagnostic test is most appropriate for initial assessment?

• A. Radiographs
• B. Hoof testers
• C. Ultrasound
• D. Blood work

Answer: (B)

When laminitis is suspected, you want a quick, reliable clue about whether the hoof is painful, which guides immediate management. Hoof testers do just that by applying pressure to the sole and frog to see if the horse flinches or pulls away. A pronounced reaction supports the presence of hoof pain consistent with laminitis and helps you establish dominance of the problem right away. It’s quick, noninvasive, and can be done in the field, making it the most practical initial assessment tool.

Radiographs, while essential for evaluating the degree of pedal bone changes and guiding prognosis, may not show early structural changes and require equipment and time, so they’re typically used after the initial evaluation to assess progression. Ultrasound isn’t routinely helpful for diagnosing laminitis because it doesn’t reliably image the laminae. Blood work can reveal systemic issues or secondary problems but doesn’t confirm laminitis or guide the immediate hoof-focused management you're aiming for at the first exam.
