When your pet needs specialized care, a veterinary laboratory plays a critical role in providing accurate diagnostics and treatment guidance.
In this article, we’ll explore what veterinary labs do, what services they offer, how to find one near you, and why choosing the right lab matters.
Let’s start by understanding exactly what a veterinary laboratory is and why it’s essential in modern animal healthcare.
Understanding Veterinary Labs
Just like human medical labs, veterinary labs follow strict protocols to ensure accuracy and reliability.
Larger labs may also offer molecular diagnostics, genetic screening, and advanced pathology services.
In the US, veterinary laboratories can operate as standalone diagnostic centers, be integrated into veterinary hospitals, or work as part of nationwide networks.

What Tests Do Veterinary Labs Offer?
Veterinary laboratories perform a wide range of tests that help veterinarians evaluate an animal’s health.
For more specialized diagnostics, veterinary labs offer cytology (examining cells under a microscope), biopsies, hormone level testing (such as thyroid or cortisol), and infectious disease panels.
Whether a veterinarian is laboratórios veterinarios confirming diabetes, laboratório veterinário ribeirão preto diagnosing para ver acesse cancer, or screening for zoonotic diseases, a reliable veterinary lab ensures the right data is available for informed decisions.
Locating a Veterinary Laboratory in Your Area
Many vet clinics also have in-house labs for basic tests and refer complex cases to specialized facilities.
Look for labs certified by organizations like the American Association of Veterinary Laboratory Diagnosticians (AAVLD), which ensures high-quality standards.
If you’re a pet owner seeking direct access to a lab for second opinions or advanced testing, contact the lab to understand their intake process—some require referrals, while others accept samples directly.

When to Use a 24-Hour Veterinary Lab
Knowing when to use each type can make a significant difference in urgent cases.
These labs are often linked to emergency veterinary hospitals and specialize in handling critical cases at any time of day or night.
For non-urgent screenings, wellness panels, or follow-up testing, standard labs are usually sufficient.
How Diagnostic Labs Protect Animal Health
While physical exams provide valuable insights, they can’t reveal everything—lab tests uncover hidden conditions, confirm clinical suspicions, and track progress over time.
Blood tests, for example, can detect kidney or liver dysfunction early, allowing for interventions that prolong quality of life.
With the support of a trusted veterinary laboratory, you and your veterinarian can work together to make informed, timely, and effective healthcare decisions.
