What Is Pet Laboratory Testing?

Pet laboratory testing encompasses a range of diagnostic tools used to evaluate your pet’s internal health. While a physical exam gives our team valuable information about what we can see and feel, laboratory testing reveals what’s happening beneath the surface. Blood work, urinalysis, fecal testing, and other diagnostics—including supplementary X-ray and ultrasound imaging—provide a more complete picture of your pet’s health and help our team make informed, accurate decisions about their care.

Laboratory testing is recommended in a variety of situations, from routine wellness screening to pre-surgical evaluation, illness workup, and ongoing monitoring of chronic conditions. For many pets, routine diagnostic testing is one of the earliest ways we can identify developing health concerns before they become more serious.

Laboratory Testing as Part of Preventive Care

Diagnostic testing isn’t only for sick pets. Incorporating routine laboratory screening into your pet’s annual wellness exam allows our team to establish baseline values for your individual pet and track changes over time. What falls within a normal range can vary from pet to pet, and having a history of results makes it easier to identify meaningful shifts in your pet’s health before symptoms appear.

For pets on long-term medications, regular blood monitoring helps ensure the medication is working as intended and that organ function remains stable. Our team will recommend an appropriate testing schedule based on your pet’s age, health status, and any ongoing treatments.

Types of Laboratory Testing We Offer

Our in-house veterinary diagnostics capabilities allow us to perform a wide range of tests without the delays associated with sending samples to an outside lab. This means our team can often review results during or shortly after your pet’s appointment and begin discussing next steps with you the same day.

Blood Work

Pet blood testing is one of the most informative diagnostic tools available in veterinary medicine. A complete blood count, or CBC, evaluates the red blood cells, white blood cells, and platelets in your pet’s blood, providing information about immune function, hydration, anemia, and infection. A blood chemistry panel assesses organ function, including the liver, kidneys, and pancreas, and can help identify metabolic conditions such as diabetes.

Urinalysis

Urine testing provides valuable information about kidney function, hydration status, and the presence of infection, crystals, or other abnormalities in the urinary tract. Urinalysis is often performed alongside blood work to give our team a more complete picture of your pet’s metabolic health.

Fecal Testing

A fecal exam screens for intestinal parasites, including roundworms, hookworms, whipworms, Giardia, and coccidia. Because many pets with intestinal parasites show few or no outward symptoms, routine fecal screenings are an important part of a comprehensive parasite control plan.

Additional Diagnostics

Depending on your pet’s symptoms and health history, our team may recommend additional testing such as thyroid panels, heartworm testing, tick-borne disease screening, or cytology. We’ll always explain why a particular test is being recommended and what we hope to learn from the results.

Why Timely Diagnostics Matter

When a pet is unwell, time is often a critical factor. In-house veterinary diagnostics allow our team to move quickly from assessment to diagnosis to treatment without waiting days for outside lab results to return. This is particularly valuable in urgent situations where a faster answer can make a meaningful difference in your pet’s outcome.

Even outside of urgent care scenarios, timely diagnostics support better veterinary care across the board. When our team has access to accurate, current information about your pet’s internal health, every recommendation we make is grounded in a clearer understanding of their individual needs.

Diagnostic Expertise You Can Trust

Our team at Porter Square Veterinarian approaches every diagnostic workup with the same thoroughness and attention to detail that we bring to all aspects of your pet’s care. We don’t order tests arbitrarily; every recommendation is made with a clear clinical purpose in mind, and we take the time to explain our reasoning and walk you through your pet’s results in plain language.

We believe informed pet owners are better equipped to make decisions about their pet’s care, and clear communication about diagnostic findings is a core part of how we practice veterinary medicine.

FAQs About Pet Laboratory Testing

How should I prepare my pet for blood work?

K
L
For many routine blood panels, fasting for 8 to 12 hours beforehand is recommended to ensure accurate results, particularly for glucose and certain liver and kidney values. Our team will let you know in advance whether fasting is needed for your pet's specific tests.

How long does it take to get results?

K
L
Because we perform many diagnostics in-house, results are often available within the same appointment or shortly after. If samples need to be sent to a reference laboratory for specialized testing, turnaround time may be longer. We'll let you know what to expect for your pet's specific situation, and our team will contact you with results as soon as they're available.

My pet seems healthy—do they still need blood work?

K
L
Yes, routine pet blood testing is valuable even for pets who appear healthy. Many conditions, including kidney disease, liver dysfunction, and thyroid disorders, develop gradually and may not produce obvious symptoms until they are well advanced. Routine screening gives our team the opportunity to catch these changes early.

Can laboratory testing help with my senior pet's care?

K
L

Absolutely. Senior pets benefit significantly from more frequent diagnostic monitoring, as age-related changes in organ function can develop over a relatively short period. Regular blood work and urinalysis help our team stay ahead of these changes and adjust your pet's care plan accordingly. Learn more about our senior pet care services.

What if my pet's results come back abnormal?

K
L
An abnormal result doesn't always indicate a serious problem, but it does give us important information to act on. Our team will contact you to discuss any concerning findings, explain what they may indicate, and outline the recommended next steps, whether that means a follow-up test, a treatment plan, or a referral for further evaluation.
