Diagnostics &amp; Imaging: Getting Answers, Guiding Better Care When your pet isn’t feeling their best—or when something just seems “off”—diagnostics and imaging help us find the answers quickly and accurately. These tools allow veterinarians to see what’s happening inside your pet’s body without invasive procedures, making it easier to diagnose illness, monitor ongoing conditions, and plan effective treatment.Why Are Diagnostics Important?Pets can’t tell us what’s wrong, and early signs of illness are often subtle. Advanced diagnostics help us catch problems early—when they’re most treatable—and ensure we’re not guessing when it comes to your pet’s health.Whether it’s a routine wellness check or something more urgent, in-house diagnostics give your veterinarian a clearer picture of your pet’s internal health.What Types of Diagnostic Services Do We Offer?Our hospital offers a wide range of diagnostic and imaging tools, including:Bloodwork &amp; Lab Testing<ul><li>Complete Blood Count (CBC)</li><li>Blood chemistry panels (organ function, electrolytes)</li><li>Thyroid and hormone testing</li><li>Tick-borne disease screening</li><li>Feline leukemia/FIV testing</li><li>Heartworm testing</li></ul>Urinalysis &amp; Fecal Testing<ul><li>Detects infections, crystals, or kidney issues</li><li>Screens for internal parasites, Giardia, and more</li></ul>Digital Radiology (X-Rays)<ul><li>High-quality imaging of bones, chest, abdomen, and joints</li><li>Useful for identifying fractures, arthritis, foreign bodies, tumors, or lung disease</li></ul>Ultrasound Imaging<ul><li>Offers a real-time look at soft tissues like the liver, bladder, kidneys, or heart</li><li>Ideal for detecting fluid buildup, tumors, pregnancy, or organ changes</li></ul>In-House Laboratory<ul><li>Fast turnaround for urgent or same-day cases</li><li>Supports more accurate diagnosis and quicker treatment decisions</li></ul>When Might Your Pet Need Imaging or Lab Tests?<ul><li>Vomiting or diarrhea</li><li>Limping or pain</li><li>Labored breathing or coughing</li><li>Weight loss or appetite changes</li><li>Lethargy or behavioral changes</li><li>Monitoring chronic illnesses</li><li>Pre-surgical evaluations or senior wellness screening</li></ul>What to ExpectYour veterinarian will walk you through the purpose of each test or imaging recommendation, what the results may tell us, and next steps. Most procedures are non-invasive, and we prioritize your pet’s comfort and safety throughout.<div data-type="horizontalRule"><hr></div>Diagnostics are the bridge between symptoms and solutions.
