An Overview of Veterinary Diagnostic Lab Tests

All pet owners want their pets to live long and happy lives. This can be accomplished by taking the pet to the vet for regular checkups. On the other hand, diagnostic tests are required for a veterinarian to better understand the pet’s health. Pets’ outer appearance, like humans, may not reflect their interior state. However, appropriate diagnostic testing may assist the veterinarian in diagnosing and treating a problem before it worsens. Among the obligatory diagnostic tests for your pet are the following:

Clinical Chemistry

Clinical chemistry is the study of a specimen’s chemical makeup. Other bodily fluids may also be studied. Typically, the sample is the liquid component of the blood (serum or plasma). Clinical chemistry and physical exams for pets are critical for establishing the health of various organs (kidneys, liver, etc.).

They can help in the diagnosis of disorders like diabetes and pancreatitis. These tests may also be used to evaluate your pet’s therapy response.


Cytology studies individual cells, structure and origin, function(s), and death. Pathologists can provide a veterinarian with information on the cells in your pet’s body. Tissue or fluid samples are obtained using a fine-needle biopsy, and slides are created and stained for microscopic inspection to determine the types of cells present.

Fluid Analysis

Aside from blood, fluid analysis studies other body fluids (urine, joint fluid, etc.). Experts that evaluate body fluids work closely with other professionals to provide information about an animal’s health. Typically, fluid analysis involves checking for cells and proteins in the sample. Additionally, clinical chemistry testing for specific drugs may be performed.


Hematology studies the biological components of the blood and how they vary in health and illness. The most common blood test is a full blood count. This test provides basic information about anemia, inflammation, and clotting by assessing the number and kind of cells circulating in the bloodstream. If you observe any inflammation in your pet’s gums, look up”veterinary dentist near me” to determine if lab testing is required.


Histology studies the microscopic anatomy (structure) of plant and animal tissues. Pathologists specializing in histology examine small tissue samples to determine whether they are healthy or diseased. Pathologists have studied the causes and effects of disease and can frequently pinpoint the reason for abnormal tissue shapes or cells.

If your veterinarian suspects cancer or another condition that causes tissue changes, he or she will send small tissue samples to a pathologist.


Microbiology studies single-celled organisms such as bacteria, viruses, fungi, and other microbes. Microbiology professionals in a veterinary laboratory can perform numerous tests to detect signs of sickness. Growing and then identifying viruses, bacteria, and fungi is a common procedure.


Serology examines blood serum and other body fluids. Most serologic tests assess the number of antibodies (called the titer) present and reactive to a certain pathogenic microorganism. A high amount of antibodies, or an increase in their level between two samples collected a few weeks apart, suggests that an animal has been exposed to the bacterium and its immune system has generated antibodies against the infectious agent.


Toxicology investigates how poisons impact animals. Let’s assume that your veterinarian on or any other place suspects your pet has been poisoned. In that instance, he or she will collect samples for toxicologic testing to assess the type of toxin and the amount of potential damage.


Veterinarians use various veterinary technology to diagnose diseases, monitor disease progression or drug response and test healthy animals for underlying ailments. Most veterinary hospitals have a diagnostic laboratory packed with numerous diagnostic devices to quickly examine your pet’s health and determine what therapy is required. When you observe unusual symptoms or behavior in your pet, schedule an appointment with a reputable clinic that offers these services.
