Our hospital uses advanced digital X-ray technology to provide high-resolution images with lower radiation exposure, keeping your pet safe while enabling faster, more accurate diagnoses. Digital radiology allows our veterinary team to:
  • Capture clear images in seconds for timely treatment decisions
  • Detect fractures, joint problems, and other skeletal issues with exceptional accuracy
  • Examine the chest and abdomen for conditions such as heart disease, pneumonia, or gastrointestinal blockages
  • Easily share images with specialists for collaborative evaluations when needed
By using digital imaging, we help pet owners in Lake Forest and the surrounding South Orange County communities receive quicker results and more precise treatment plans.

Digital Dental X-Rays

Many dental problems in pets occur below the gum line, where they can’t be seen during a standard oral exam. Our digital dental X-rays provide a detailed look at the roots, bones, and internal anatomy of your pet’s teeth, helping us identify periodontal disease, tooth fractures, and other hidden dental issues early.

This technology is faster, safer, and more comfortable for pets, using lower radiation doses compared to traditional X-rays. With immediate, high-quality results, we can quickly develop a customized treatment plan to keep your pet’s mouth healthy and pain-free.

In-House Laboratory Testing for Fast Results

At Bliss Animal Hospital, we understand that time matters when your pet is sick or needs pre-anesthetic testing before surgery. Our comprehensive in-house lab delivers same-day results for urgent cases, allowing us to start treatment right away.

For more advanced or specialized diagnostics, we partner with trusted reference laboratories, typically providing results within 1–3 business days. This combination of in-house speed and specialist expertise ensures that every pet in Lake Forest and surrounding South Orange County communities receives accurate, timely, and tailored care.

Our in-house testing options include:

Measures red and white blood cells, platelets, and more to help detect infections, inflammation, anemia, immune disorders, and clotting issues. This test is frequently used for both routine checkups and emergency evaluations, especially when pets are lethargic, have a fever, or show other signs of illness.

Evaluates liver, kidney, and pancreas function, along with glucose and electrolyte levels. It’s a valuable tool for identifying dehydration, metabolic imbalances, toxin exposure, and organ stress. Often used for both healthy pets during wellness exams and pets showing symptoms like vomiting, weight changes, or loss of appetite.

Assesses thyroid hormone levels, which control metabolism. This test is essential for diagnosing hypothyroidism in dogs and hyperthyroidism in cats. It’s recommended for pets with unexplained weight changes, skin or coat issues, or behavioral changes, particularly in middle-aged or senior pets.

Detects heartworm disease, a serious condition transmitted by mosquitoes. This test is vital for dogs—even those on prevention medication—to ensure they remain heartworm-free. It’s commonly performed during annual wellness visits and often paired with tick-borne disease testing.

Screens for Feline Leukemia Virus (FeLV) and Feline Immunodeficiency Virus (FIV), two serious viral conditions in cats. This test is especially important for outdoor cats, new adoptions, or cats exposed to unknown animals, and helps guide long-term care and disease management in multi-cat households.

Confirms your pet’s body is ready for anesthesia by evaluating blood counts and organ function. This screening reduces surgical risks and allows us to tailor anesthesia safely to your pet’s needs. It’s a required step before procedures such as spay/neuter, dental cleanings, and mass removals, especially for older or at-risk pets.

Checks for intestinal parasites, including roundworms, hookworms, whipworms, and certain protozoa. Regular fecal testing is critical for early detection and treatment, protecting both your pet’s health and your family’s, as some parasites can be transmitted to humans. We recommend fecal exams as part of annual wellness visits and whenever gastrointestinal symptoms like diarrhea or weight loss are present.

Provides valuable insight into your pet’s kidney and bladder health while helping detect conditions such as urinary tract infections, kidney disease, diabetes, and dehydration. This simple, non-invasive test is often recommended during annual wellness exams, when pets show changes in urination habits, or as part of a comprehensive diagnostic workup for sick pets.

At Bliss Animal Hospital in Lake Forest, our in-house digital ultrasound enhances the way we diagnose and treat pets. This non-invasive, pain-free imaging tool provides real-time insights into your pet’s health, helping us detect problems earlier and with greater accuracy.

Ultrasound imaging allows our veterinary team to:
  • Examine organs such as the liver, kidneys, spleen, and bladder for abnormalities
  • Detect tumors, cysts, and internal fluid that may not be visible on X-rays
  • Support safer, guided procedures like biopsies
  • Monitor internal health during surgery or emergencies
For more complex cases, we partner with a board certified veterinary specialist who visits our hospital to perform specialized imaging and provide expert interpretations. This means your pet benefits from specialist-level care without the need to leave Lake Forest, CA.

Frequently Asked Questions about Pet Diagnostic Testing

Diagnostic testing includes laboratory tests, digital imaging (X-rays, ultrasound), and specialized procedures that help veterinarians understand what’s happening inside your pet’s body. These tools allow us to assess organ function, detect infections, locate injuries, and identify underlying conditions before they become more serious.

Early and accurate diagnostics are critical for your pet’s health. By identifying issues early—sometimes before symptoms even appear—we can create a treatment plan that’s more effective, less invasive, and often less costly. Whether your pet is here for a wellness visit, an emergency, or pre-surgical testing, diagnostics help us make the most informed decisions about their care.

If your pet is showing changes in behavior, appetite, energy levels, urination, bowel habits, or unexplained weight changes, diagnostic testing can help pinpoint the cause. Your veterinarian may also recommend tests during routine checkups to screen for early signs of disease or as a pre-anesthetic precaution before procedures.

At Bliss Animal Hospital in Lake Forest, we offer a wide range of in-house and external diagnostic services, including:
  • Digital X-rays for imaging bones, joints, and internal organs
  • Dental X-rays for hidden oral health issues
  • Ultrasound imaging for real-time evaluation of internal organs
  • In-house blood work for quick health assessments
  • Fecal exams and urinalysis to detect parasites, infections, or metabolic issues
  • Specialized panels like thyroid testing, FeLV/FIV screening, and pre-anesthetic evaluations

Most in-house tests provide same-day results, which is especially important for urgent cases. More specialized tests sent to reference laboratories typically return results within 1–3 business days. Your veterinarian will review the findings with you and discuss the next steps for your pet’s care.

Most imaging procedures, like digital X-rays or ultrasound, do not require anesthesia and are quick and comfortable for your pet. However, sedation may be recommended for pets who are extremely anxious, in pain, or unable to stay still during the procedure. Dental X-rays are typically performed while your pet is under anesthesia for a dental cleaning, ensuring both accuracy and safety.
