Diagnostic Services


Radiographs (X-rays) are extremely helpful for diagnosing and monitoring many medical and surgical conditions. Radiographs are useful in examining your pet's bones, lungs, heart, abdomen, oral cavity and other areas of the body. A radiographic survey can spot a fractured bone, detect tumors, help with the diagnosis of heartworm disease or locate an obstruction or foreign body in your pet's intestine or stomach. When used in conjunction with other diagnostic procedures like ultrasound, radiographs can accurately diagnose problems, making treatment faster and easier for your pet and your veterinarian.

Terra Linda Veterinary Hospital utilizes radiographic technology including a digital dental radiograph system in order to gain timely access to radiographic studies for the diagnosis and treatment of numerous conditions. 


Ultrasound technology is a pain free, totally non-invasive technique that uses high frequency sound waves to produce a real-time image of your pet's internal organs. Often considered more exact than radiographs, ultrasound provides a digital moving image of what is happening inside your pet's body.

It is particularly useful in viewing your pet's abdominal organs including the spleen, kidneys, liver, and gallbladder. It can also be used to evaluate heart functions, bladder scans and other areas such as the thyroid glands, testicles and mammary glands.

Ultrasound also works well in conjunction with other diagnostic tools and a wide range of diagnostic procedures. For example, if a radiograph shows a lesion on your pet, an ultrasound can determine the origin of the lesion and whether it has spread elsewhere in your pet's body. Using the ultrasound image as a guide, surgical biopsies can be obtained without major surgery and your pet can often go home the same day. Ultrasounds are typically not stressful for your pet and take anywhere from 30 to 60 minutes to perform.


Veterinary Endoscopy is an extremely useful procedure that aids in the diagnosis and treatment of problems occurring in the upper and lower gastrointestinal (GI for short) tracts. With an endoscope, we can perform a more complete examination of the GI tract, including the esophagus, stomach, and some areas of the intestines.

The endoscope allows the veterinarian to visualize areas that would normally not be accessible without invasive surgery. The scope is equipped with a lighted camera and pictures can be transferred to a monitor to be better evaluated by the veterinarian. Using the scope, a doctor can diagnose gastrointestinal disorders, cancerous growths, polyps and much more.

The endoscope is useful in obtaining samples of potentially infected or cancerous material. When performing a biopsy under such conditions, the endoscope serves as the "eye" of the veterinarian, allowing him or her to obtain the best possible samples for evaluation. This procedure is extremely helpful in diagnosing malignancies in the GI tract as well as GI disorders, such as Inflammatory Bowel Disease.

Another function of the endoscope is to aid the veterinarian in the removal of foreign bodies. A foreign body is anything that "does not belong" in the animal's GI tract. Often, animals swallow things that they should not, including toys, buttons, and in one instance, a sewing needle! Using the endoscope as a guide, the veterinarian may be able to remove such objects using a special instrument, rather than resorting to a major surgery.

Terra Linda Veterinary Hospital partners with Dr. Amy Allen, a board certified internist, to perform in-house endoscopic procedures, which include foreign body retrieval, upper and lower GI with biopsies when needed, rhinoscopy, pharyngoscopy, bronchoscopy, bronchial brushings, washes and sampling.

Laboratory Services

Performing preventative medicine as well as diagnosing emergent internal health issues requires the ability to perform a wide range of laboratory tests on blood, urine, feces, and biopsied tissue. Without timely access to precise laboratory test results (blood testing, biopsies, microscopic examinations, bacterial culture sensitivity) it can be difficult to make an accurate diagnosis or assessment of your pet's health.

At Terra Linda Veterinary Hospital we have a complete laboratory at our disposal that allows us to perform routine blood screening, heartworm testing, cytology, histopathology, as well as range of advanced, specialized diagnostic testing services.
