Diagnostic Services

Performing preventative medicine as well as diagnosing emergent health issues requires the ability to perform a wide range of laboratory tests on blood, urine, feces, and biopsied tissue. Newer PCR panels at our reference lab, testing a sample for the DNA of a pathogen, provide rapid turnaround for tests that used to take weeks to get an answer. Some of our diagnostic testing includes:

  • Routine blood screening (including in house and reference lab)(both Heartworm testing (after 6 months of age; recommended yearly even if on heartworm preventive)
  • Cytology (in house and reference lab)
  • Histopathology
  • Urinalysis and screening for protein, or cortisol when indicated
  • Thyroid
  • Cardiac biomarkers (especially useful for older cats; more sensitive than a chest x-ray)
  • Fecal Analysis for parasites (screening and PCR)
  • Tick Borne Disease Screening
  • Culture and Sensitivity (urine and tissue)
  • Fungal culture and PCR panels
  • Skin tests for mites, cytology and fungal
  • Ear cytology

Radiographs (X-rays) are extremely useful in examining your pet’s bones, lungs, heart, abdomen, oral cavity and other areas of the body. Radiographs can spot a fractured bone, detect tumors, help with the diagnosis of heartworm disease or locate an obstruction or foreign body in your pet’s intestine or stomach. We use digital radiographic technology including a digital dental radiograph system in order to gain timely access to radiographic studies for the diagnosis and treatment of numerous conditions. Staff veterinarians are available for initial evaluation. Radiographic images are often reviewed by a board-certified radiologist via telemedicine. Turnaround for results are often within 24 hours.

Ultrasound technology is particularly useful in viewing your pet’s abdominal organs including the spleen, kidneys, liver, and gallbladder. Ultrasound technology is a pain-free, totally non-invasive technique that uses high-frequency sound waves to produce a real-time image of your pet’s internal organs. Often considered more exact than radiographs and often used in conjunction with radiographs for a complete picture, ultrasound provides a digital moving image of what is happening inside your pet’s body.
