Pet Testing & Diagnostic Services
Serving Fair Oaks, Rancho Cordova, Carmichael, and surrounding communities
When your pet isn’t feeling their best—or when something just seems “off”—you want answers, fast. At Fair Oaks Pet Hospital, we use advanced diagnostic testing to uncover health concerns quickly. Whether your pet needs a blood test, an X-ray, or an ultrasound, our goal is to detect issues early, so we can create an effective treatment plan right away.
-
In-House & Reference Lab Bloodwork
We use blood tests to check your pet’s health, diagnose illness, and monitor ongoing conditions. For urgent issues, our in-house lab provides fast results—often the same day. For more comprehensive panels, we send samples to a trusted reference lab. These tests check for a wider range of conditions and can be reviewed by veterinary specialists when needed. We’ll explain the results clearly so you understand what they mean and what comes next.
-
Digital X-Rays
X-rays give us an overall view of your pet’s bones, joints, and internal organs. Digital imaging helps us diagnose injuries, detect masses, evaluate heart and lung function, and more—all with minimal stress for your pet. Digital radiography is fast, non-invasive, and often performed during a single visit.
-
Ultrasound
Ultrasound provides a detailed view of soft tissues like the liver, kidneys, bladder, and heart. It’s especially useful for diagnosing conditions that are difficult to see on X-rays, such as subtle changes to internal organs, small foreign materials, or gastrointestinal problems. Ultrasound is a powerful tool to investigate hidden or elusive health problems.
-
Cytology
If your pet has a lump, skin issue, or ear infection, cytology allows us to tailor our treatment to fit your pet's specific needs. By evaluating samples under a microscope, we can often determine whether a lump is benign or needs further testing, and we can quickly identify bacteria, yeast, or abnormal cells in infections.
We understand how overwhelming lab results can be. That’s why we take the time to walk you through every test result and discuss what comes next. Thoughtful diagnostics paired with clear communication is how we help you make confident, informed decisions for your pet.

The hospital offers comprehensive diagnostics including bloodwork, urinalysis, fecal testing, digital X-rays, ultrasound, and cytology. These tools help identify health problems early and guide precise treatment.

-
Most diagnostic tests are quick and minimally invasive. Blood draws, X-rays, and ultrasounds are generally well tolerated. Sedation may be used for anxious pets or when precise imaging is required.
