What Is an In-House Veterinary Laboratory?

An in-house veterinary laboratory is a diagnostic facility located within the clinic itself, allowing our team to analyze blood samples, urine, and other specimens on-site rather than sending them to an external lab and waiting days for results. For pet owners, that distinction is significant—it means our doctors can review findings, discuss results, and begin treatment during the same visit or within hours, rather than overnight or longer.

At Russell Veterinary Services, our in-house laboratory is a core part of how we deliver thorough, timely veterinary care. Whether we’re running pre-anesthetic bloodwork before a dental procedure, screening for a suspected illness, or monitoring a pet with a known chronic condition, our diagnostic capabilities allow us to act quickly and with confidence.

Our In-House Laboratory Services

Our on-site laboratory supports a broad range of veterinary diagnostic needs. While some complex or specialized testing may still be referred to an outside laboratory, the majority of the most common and time-sensitive diagnostics can be completed right here.

Blood Testing & Chemistry Panels

Pet blood testing is one of the most informative diagnostic tools available in veterinary medicine. A blood panel can reveal a tremendous amount about your pet’s internal health—often identifying problems that aren’t yet causing visible symptoms. Our in-house laboratory can perform:
  • Complete blood counts (CBC)—evaluating red blood cells, white blood cells, and platelets
  • General chemistry panels—assessing overall organ function and metabolic health
  • Liver enzyme screening—identifying inflammation, damage, or dysfunction in the liver
  • Renal (kidney) profiles—evaluating kidney function and detecting early signs of kidney disease
  • Pancreatic evaluation—screening for conditions such as pancreatitis
liver

Urinalysis

Urine testing provides valuable information about kidney function, hydration status, urinary tract infections, and other systemic conditions. Urinalysis is often run alongside blood panels to give our doctors a more complete picture of your pet’s health.

Pre-Anesthetic Bloodwork

Before any procedure requiring anesthesia—including pet dental cleanings and soft tissue surgery—we require a blood panel to confirm your pet is healthy enough to be safely sedated. Our in-house laboratory allows us to process these results quickly, so your pet’s procedure can proceed on schedule without unnecessary delays.

Outside Laboratory Referrals

While our in-house capabilities cover a wide range of diagnostic needs, there are cases where specialized or complex testing requires an outside reference laboratory. In those situations, we coordinate the process on your behalf—collecting and submitting the samples and following up with you as soon as results are returned. You’ll never be left to navigate that process alone.

Disease-Specific Testing

Our laboratory also supports targeted disease screening for some of the most serious infectious conditions affecting companion animals, including:

  • Feline leukemia virus (FeLV) and feline immunodeficiency virus (FIV) testing for cats
  • Parvovirus testing for dogs

These tests are especially important for new pets, animals with unknown vaccination histories, or pets presenting with symptoms consistent with these diseases.

Why Fast, Accurate Diagnostics Matter

In veterinary medicine, time is often a critical factor. Many conditions—from acute infections and organ dysfunction to systemic disease—progress quickly, and delays in diagnosis can narrow treatment options and worsen outcomes. The ability to run diagnostic testing in-house and review results the same day isn’t just convenient; it’s genuinely better medicine.

Early detection also matters for conditions that develop gradually over time. Routine bloodwork can identify shifts in kidney function, liver enzymes, or blood cell counts long before your pet shows any outward signs of illness—giving us the opportunity to intervene early, when treatment is most effective and least invasive. This is one of the most compelling reasons we recommend incorporating pet wellness exams with routine bloodwork screening, particularly for middle-aged and senior pets.

For pets already managing a known condition—such as diabetes, hypothyroidism, or kidney disease—regular in-house laboratory monitoring allows our team to track how well a treatment plan is working and make timely adjustments as needed.

Veterinary Diagnostics Backed by Experience and On-Site Technology

At Russell Veterinary Services, our in-house diagnostic capabilities are part of a broader commitment to providing thorough, efficient care without requiring pet owners to navigate referrals for routine testing. Our veterinary team reviews every result in the context of your pet’s full health history—not as isolated numbers, but as part of an ongoing picture of their well-being.

When results indicate that something needs further investigation, we have additional tools on-site to support the next step—including digital X-ray and ultrasound imaging for cases where internal visualization can help clarify a diagnosis. Our goal is always to give you clear, accurate information as efficiently as possible, so you and your pet can move forward with confidence.

Pet Laboratory FAQs

Why does my healthy pet need bloodwork?

Even pets that appear completely healthy can have underlying conditions that don’t yet show outward symptoms. Routine pet blood testing establishes a normal baseline for your individual pet and allows our team to detect gradual changes over time—often identifying early kidney disease, thyroid dysfunction, anemia, or other conditions long before they become serious. We recommend baseline bloodwork for adult pets and more frequent panels for senior animals.

How long does it take to get results from your in-house lab?

Most in-house testing can be completed within the same appointment or within a few hours. Our doctors will review results with you as soon as they’re available and walk you through what the findings mean for your pet’s care.

My pet was just tested at another clinic. Do I need to repeat the bloodwork?
Not necessarily. If you have recent records from another veterinary practice, please bring them to your appointment, and our team will review them. In some cases, prior results are sufficient; in others, we may recommend updated testing depending on how much time has passed or what we find during the physical exam.
What is pre-anesthetic bloodwork, and why is it required?

Pre-anesthetic bloodwork is a blood panel run before any procedure requiring sedation or general anesthesia. It checks for conditions—such as anemia, low platelet counts, or compromised organ function—that could increase anesthetic risk. We require this step for all anesthetic procedures because it allows us to identify and address potential concerns before your pet goes under, significantly improving safety.

What happens if my pet needs testing that your lab doesn't offer?

For specialized or advanced diagnostics beyond our in-house scope, we coordinate with an outside reference laboratory on your behalf. We handle sample collection and submission, and we’ll follow up with you directly once results are returned.

Do you run bloodwork for large animals as well?

Our in-house laboratory primarily supports our small animal patients. For large animal diagnostic needs, please call our team to discuss what testing is available and how we can best support your animals.
