In-House Veterinary Laboratory:

Achieving Quick & Accurate Diagnoses


At Town & Country Animal Hospital, we provide a wide range of pet health services to Fairfax and Vienna, Virginia area pets and their families. From pet wellness to critical care, our dedicated veterinarians and staff stand ready to help however we can.

One of the tools we rely on to provide top-quality care is our in-house laboratory. It enables us to obtain the test results we need to accurately diagnose and treat your pet in a timely manner. Here are a few of the ways that pet patients benefit from it:

  • Parasite prevention—Heartworm and fecal tests are an important part of your pet’s overall wellness care. They enable our veterinarians to eradicate any parasites present and suggest appropriate prevention measures going forward.
  • Preoperative blood screenings—Prior to any veterinary surgery procedures, it’s essential to conduct a blood work profile to ensure that your pet is healthy enough to be placed under anesthesia.
  • Specialized blood tests—As pets age, they become prone to developing certain diseases. Our veterinarians will recommend blood tests as needed to check senior pets’ hormone levels and organ function.
  • Emergency veterinary care—Whether it’s due to a car, another animal, or a sudden illness, when critical care is needed, we will be there for your pet. Our in-house laboratory can produce test results in 30 minutes, enabling our veterinarians to begin treatment right away.

Types of Tests

Depending upon a pet’s specific circumstances, there are a number of laboratory tests that may be helpful in identifying illness or disease. These include:

Blood chemistry panel—Our veterinarians use this diagnostic tool to examine your pet’s organ function. It enables us to check essential elements of your pet’s blood—such as enzyme and electrolyte levels—and can reveal whether he or she is experiencing liver disease, a kidney infection, or issues with the pancreas or gall bladder.

Urinalysis—This test is used to help identify a variety of pet illnesses, ranging from urinary tract infections to kidney disease and diabetes.

Complete blood count (CBC)—This test enables us to determine how many red blood cells, white blood cells, and platelets are present in your pet’s bloodstream. When a pet’s red blood count is low, it indicates that he or she is anemic. If it’s high, then the patient is likely dehydrated.

When a white blood cell count is low, it indicates a bad infection. The presence of a high white blood cell count could signal the presence of a disease, such as cancer. A low platelet count could suggest autoimmune and tick-borne diseases.

In each of these cases, the CBC provides much-needed cues, enabling our veterinarians to narrow down the specific causes of your pet’s condition.

Our in-house laboratory is just one of the valuable veterinary diagnostic tools we use to provide your pet with the exceptional care he or she deserves.
