Blood Test

Clinical pathology involves the laboratory evaluation of blood, fluids or body tissues in order to identify existing disease. Common laboratory tests include blood chemistries, complete blood counts, blood clotting times, urinalysis, faecal tests, biopsy examination, cultures and infectious disease testing.

Our animal hospital is equipped with an in-house laboratory that allows our veterinarians to quickly perform many of these diagnostic tests to achieve an accurate and rapid diagnosis. This is especially important in very ill animals and those requiring immediate or emergency treatment. Some more specialised tests may need to be performed by an external veterinary laboratory. Our in-house laboratory can provide results very quickly. Specialised testing may take 12-24 hours for blood results or up to 14 days for biopsy results, depending on the nature of the test being performed. Ask your veterinarian when to call for your pet’s laboratory results.

Common types of blood tests for pets

1. Complete blood count (CBC)

Measures the number and types of blood cells (red blood cells, white blood cells, and platelets).
Helps diagnose infections, anemia, inflammation, and blood clotting problems.

2. Blood chemistry panel

Evaluates the function of organs such as the liver, kidneys, and pancreas.
Includes tests for blood glucose, proteins, electrolytes, enzymes, and more.
Useful for diagnosing conditions like kidney disease, liver dysfunction, diabetes, and metabolic disorders.

3. Thyroid function test
Measures levels of thyroid hormones to detect hypothyroidism or hyperthyroidism, especially in dogs and cats.

4. Electrolyte panel

Assesses levels of sodium, potassium, and calcium in the blood.
Helps diagnose dehydration, kidney disease, and other metabolic disorders.

5. Heartworm test

Screens for heartworm infection, which is transmitted by mosquitoes and can be life-threatening if untreated.
Feline Leukemia Virus (FeLV) and Feline Immunodeficiency Virus (FIV) Test: Specific to cats, these blood tests check for viral infections that can weaken a cat’s immune system.

6. Parvovirus test (for dogs):
Screens for parvovirus, a highly contagious virus that affects the gastrointestinal tract of dogs.

7. Pre-anesthetic blood test:
Performed before surgery to ensure that a pet’s organs are functioning properly and that anesthesia can be safely administered.

When blood tests are needed

Routine Check-ups

Blood testing is part of a regular wellness exam, especially for older pets, to monitor health over time.

Before Surgery

To ensure the pet is healthy enough for anesthesia and surgery.

Diagnosis

To investigate symptoms such as weight loss, lethargy, vomiting, diarrhea, or changes in behavior.

Monitoring Chronic Conditions

Pets with chronic illnesses like kidney disease, diabetes, or liver disease may require regular blood tests to monitor their condition and adjust treatments.

Procedure

A small sample of blood is taken from a vein, usually in the leg or neck.

Timing

Results for common blood tests are typically available within a few hours or days.

Stress on the pet

Most pets tolerate blood draws well, but some may need to be gently restrained or comforted to minimize stress.

Benefits of blood testing for pets

Early detection: Blood tests can identify health issues before symptoms become noticeable, allowing for early treatment. Monitoring overall health: Regular testing helps ensure pets stay healthy and allows for tracking changes in health over time. Treatment guidance: Results from blood tests help veterinarians tailor treatments and monitor the effectiveness of interventions. Blood testing is a valuable part of comprehensive veterinary care, contributing to longer, healthier lives for pets.
