Diagnostic Services

As part of our commitment to provide you with access to the best medical care for your pet, we have also invested in the latest advanced diagnostic technology. After performing a thorough examination, diagnostic tests are sometimes necessary to identify the underlying cause of your pet's illness.

Digital Radiology for Lancaster AnimalsDigital Radiology

Radiographs are one of the most important diagnostic tools in all of veterinary medicine. They allow us to view the shape, size and location of organs inside your pet's body. Radiographs are extremely helpful for diagnosing and monitoring many medical and surgical conditions. X-rays are useful for examining your pet's bones, lungs, heart, abdomen, oral cavity and other areas of the body. An X-ray is capable of detecting a fractured bone, tumor, heart problem and locating an obstruction or foreign body in your pet's stomach or intestine.

Because we believe pet owners throughout the Lancaster area deserve the best possible care, we have invested in a state-of-the-art, high-quality digital X-ray machine. With the availability of digital radiography, X-rays have become far more powerful and useful than ever before. This means we can quickly take highly detailed radiographs, manipulate them to gain a better view of your pet's bones and internal organs and then display them on a computer for you to see. The veterinarians at Smith Veterinary Hospital are also able to diagnose a wide range of medical conditions with more speed and accuracy than ever before.

The Advantages of Digital Radiology

  • Digital X-rays can be saved to a disk and given to you as part of your pet's home medical record.
  • Images can be quickly shared via email to specialists when a second opinion or additional diagnosis is needed.
  • Your pet's time on the X-ray table is reduced because fewer images need to be taken.
  • Digital X-rays eliminate the need to use toxic chemicals in the film development process, decreasing the risk of exposure to our staff and the environment.
  • Digital X-ray images can be saved on a computer and they can be transmitted quickly by email to outside specialists if a referral or second opinion is necessary.


Ultrasound 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 used in conjunction with radiographs, ultrasound provides a movie of what is happening inside your pet's body. It allows our Smith Veterinary Hospital veterinary staff to look at your pet's internal organs, chest and abdomen without surgery or sedation.

Ultrasound 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, do bladder scans, pregnancy evaluations and image other areas such as the thyroid gland, testicles and mammary glands.

Ultrasound also works well in conjunction with a wide range of diagnostic tools and procedures. For example, if an X-ray shows a lesion in your pet, an ultrasound may be able to 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. Ultrasound imaging can reveal cancer, heart disease, enlarged spleens and many other conditions.

In most cases an ultrasound procedure is relatively brief and your pet can return home the same day. Most importantly, an ultrasound helps our Lancaster veterinarians make an accurate diagnosis of your pet's condition and provide effective treatment recommendations.


Endoscopy is a minimally invasive diagnostic procedure commonly used to evaluate the interior surfaces of your pet's organs through a small tube inserted into his or her body. Using an endoscope, we can accurately diagnose the cause of your pet's vomiting, diarrhea, weight loss, abdominal pain or swelling, loss of appetite or respiratory problems.

The endoscope is composed of a long tube (flexible or rigid), a light source, camera and viewing eyepiece. In addition to the fiber optic light source, there are two channels within the tube. One channel is for passing forceps, snares or biopsy instruments, allowing for the removal of foreign objects, collection of biopsy samples and removal of small polyps or tumors. Air or water can be passed through the other channel for better viewing of the tissue or organ.

Veterinary Laboratory TestingAlthough anesthesia is required to keep pets still during the endoscopic procedure, the amount and recovery time is minimal. Endoscopy has a litany of benefits over exploratory surgery, including no surgical incision, shortened anesthetic time, decreased inflammation, less stress and discomfort, and an earlier return to normal function for your pet.

Accurate diagnosis of your pet's symptoms begins with our ability to construct as complete and accurate a picture of what is going on inside your pet's body as possible. For that reason, endoscopy is recommended when routine blood and urine tests, radiographs and ultrasound do not give us the complete diagnostic picture.

In-House Laboratory

The skilled staff at Smith Veterinary Hospital maintains a full service diagnostic laboratory that allows us to perform complete blood counts, chemistry profiles, electrolytes, urinalysis, fecal exams, cytology evaluations and other valuable tests for your pet. With our advanced laboratory technology we can receive fast, accurate results, helping to determine your pet's diagnosis and what treatment therapy is required.

Our complete in-house laboratory is particularly essential to our emergency and critical care cases. We also offer several tests as part of your pet's wellness exam and specialized testing if your pet is in his or her senior years. We can often have results within 15 minutes for many tests.
