Advanced Blood Work and Urine Tests: Uncovering What You Can’t See

At Cobb & Co. Veterinary Clinic in Elgin, Illinois, we know your pet isn’t just a companion—they’re family. Your biggest goal as a pet owner is to keep them healthy, happy, and by your side for as many years as possible. That’s why routine diagnostic testing, including advanced blood work and urinalysis, is such a powerful tool in protecting your pet’s health—even when everything seems fine on the outside.

These tests can detect hidden issues before your pet shows any symptoms. And that early detection? It often makes all the difference—turning a potential emergency into a manageable condition, and improving outcomes across the board.

What Makes Diagnostics So Important?

Think of blood work and urine testing as a window into your pet’s internal health. While physical exams are crucial, they can only go so far. These tests help us catch subtle changes, guide treatment plans, and spot trouble early—before it becomes serious.

At Cobb & Co., our goal is to offer more than just treatment—we’re here for true, proactive care. That’s why our wellness approach includes thorough diagnostic testing at every life stage.

Why Routine Blood Work and Urine Testing Matters

Even healthy pets benefit from regular diagnostics. These tests can reveal:

  • Kidney and liver disease
  • Diabetes
  • Thyroid imbalances
  • Infections or inflammation
  • Dehydration
  • Early signs of age-related changes

You might not notice any symptoms, but that doesn’t mean nothing is happening. Preventive Testing for Senior Pets is especially important for dogs and cats entering their golden years.

Key Blood Tests in Veterinary Medicine

Here’s what we look at when we run blood panels:

  • Complete Blood Count (CBC): Helps us detect infection, anemia, and immune-related issues by analyzing red and white blood cells and platelets.
  • Chemistry Panels: Assess major organs like the liver, kidneys, and pancreas, as well as electrolytes and proteins.
  • Thyroid Testing: Evaluates hormone levels to detect hypothyroidism or hyperthyroidism—conditions that are common in older pets.

What Can Urine Tests Tell Us?

More than you might think.

  • Urinalysis: This test gives us insight into hydration, kidney function, infection, urinary tract health, and metabolic issues like diabetes.
  • Senior Care: Older pets often show early signs of kidney trouble or urinary tract infections through urine changes—long before they act “sick.”

What Are We Looking for—and Why It Matters

Kidney Disease

Blood markers like creatinine and BUN help identify reduced kidney function, even before symptoms like vomiting or lethargy appear. Urine protein levels also give us early warning signs.

Liver Disease

Elevated liver enzymes (like ALT or AST) on blood panels tell us when the liver is under stress or beginning to fail.

Diabetes

High blood glucose combined with sugar or ketones in the urine signals diabetes. Ongoing testing helps us adjust treatment plans as needed.

Thyroid Conditions

Too much or too little thyroid hormone can disrupt your pet’s metabolism and energy. A simple blood test identifies imbalances quickly and accurately.

Infections & Inflammation

  • CBCs show spikes in white blood cells when your pet is fighting an infection.
  • Urine tests can pinpoint urinary tract infections, kidney infections, or other problems early on.

Monitoring Chronic Conditions Over Time

For pets already diagnosed with a chronic condition, these tests become a lifeline. We use them to:

  • Adjust medications
  • Track disease progression
  • Catch complications early
  • Ensure treatment is working

Whether it’s hypothyroidism, kidney disease, or diabetes, these diagnostics help us fine-tune care and keep your pet feeling their best.

When Should These Tests Be Done?

During Wellness Exams

  • Annual testing is recommended for most adult pets to establish baselines and catch changes early.
  • Twice-a-year testing is ideal for senior pets (typically age 7+), especially for early signs of age-related disease.

If Your Pet Seems “Off”

Signs like lethargy, vomiting, weight loss, or reduced appetite often point to an underlying issue. Blood work and urinalysis help uncover the cause so we can act quickly.

Before and After Surgery

  • Pre-surgical testing ensures your pet is healthy enough for anesthesia and helps us avoid complications.
  • Post-operative monitoring helps track recovery and detect any issues, like infection or organ stress.

Why It All Matters

Routine blood work and urine tests don’t just help us find illness—they help us prevent it.

  • Early detection = better outcomes
  • Proactive care = fewer emergencies
  • Personalized treatment = healthier, happier pets

When you invest in diagnostics, you’re giving your pet a better chance at a longer, more comfortable life.
