Onsite Diagnostic Laboratory

Our Onsite Diagnostic Laboratory Means Better Veterinarian Care

At Ontario Veterinary Hospital we have a full onsite veterinary laboratory capable of performing blood work and chemical analysis. Laboratory services provided are at reduced cost and speedier than when offsite services are used.

More Rapid Diagnosis

On-site diagnostic testing has become an increasingly popular way for veterinarians to become more accurate and effective in treating their patients. Earlier treatment of problems generally means better results.

Types of Testing Available

We offer blood tests and chemical analysis. Our in-house laboratory includes comprehensive testing.

  • Serum chemistry - Blood is separated and serum is drawn and analyzed. This testing is used to assess the function of body systems. Common blood serum tests evaluate organ, hormonal and electrolyte status. They are important in evaluating senior pets, pets with exposure to toxins, those who have been vomiting or who have diarrhea. Pets receiving extended medication commonly receive this testing. It's sometimes done prior to anesthesia. Serum chemistry can help decide what further tests need to be performed.
  • Hematology - Hematology includes the study, diagnosis, treatment and prevention of blood diseases.
  • Urinalysis – Testing of urine is used to diagnose multiple disorders including urinary tract infections, kidney disease and diabetes.
  • Parasite testing – Annual parasite testing is important for both dogs and cats. It can identify intestinal parasites and help decide which flea, tick and heartworm medications to use.
  • Heartworm testing - A deadly parasite can be transmitted by a single mosquito bite. Heartworm testing is recommended annually for both cats and dogs. It’s also recommended for cats who exhibit asthma like symptoms.
  • FeLV/FIV Testing – Two lethal cat viruses are feline leukemia virus (FeLV) and feline immunodeficiency virus (FIV). When undetected they can cause premature death. Two to four percent of cats have one of these viruses.
  • Parvovirus Testing – Parvovirus can cause feline distemper. It also affects dogs.
  • Pancreatitis Testing - Serum TLI concentrationis the most favored diagnostic test of for Exocrine Pancreatic Insufficiency in dogs and cats.

Convenience and Control

On-site diagnostic testing enables us to maintain control of treatment options. Scheduling tests to suit you is more convenient and turnaround is faster. In-house testing not only saves you time but also allows you to get timely diagnosis of your pet’s disorders. When a patient is showing disturbing symptoms of pain, weakness, listlessness or vomiting it’s best to find out what the problem is rapidly to expedite recovery.

When will your vet provide diagnostic testing?

Diagnostic testing should be done on an annual basis, bi-annual basis or when a pet shows disturbing changes in energy levels or behavior. Even when your pet is happy and healthy, wellness diagnosis is important. Diagnostic testing is the most accurate way to detect health problems early on. Early detection can often lead to more complete recovery. When you bring your pet to our clinic, Ontario Veterinary Hospital, for a wellness exam we can provide laboratory tests to diagnose serious health conditions that include blood disorders, infections and cancer.
