Blood Tests and Screens

Animal blood tests and screens play a crucial role in veterinary medicine, helping veterinarians diagnose diseases, monitor organ function, assess overall health, and guide treatment decisions for animals. Here's some information about common types of blood tests and screens used in veterinary practice:

  • A CBC provides information about the cellular components of blood, including red blood cells, white blood cells, and platelets. It can help diagnose conditions such as anemia, infections, and certain cancers.

  • This panel measures various substances in the blood, including electrolytes, enzymes, proteins, and waste products. It provides information about organ function, such as the liver, kidneys, and pancreas. Abnormalities in these values can indicate diseases like liver or kidney dysfunction.

  • These tests measure thyroid hormone levels in the blood and are used to diagnose thyroid disorders such as hypothyroidism or hyperthyroidism in animals.

  • Coagulation tests evaluate the blood's ability to clot properly. They are essential for diagnosing bleeding disorders and monitoring animals on anticoagulant therapy.

  • Blood glucose tests measure the concentration of glucose in the blood and are essential for diagnosing and managing diabetes mellitus in animals.

  • These screens detect the presence of antibodies or antigens associated with infectious diseases like heartworm disease, feline leukemia virus (FeLV), feline immunodeficiency virus (FIV), and tick-borne diseases.

  • Hormone assays measure hormone levels in the blood and are used to diagnose conditions related to hormonal imbalances, such as Cushing's disease or Addison's disease.

  • Before undergoing anesthesia, animals may undergo blood tests to assess their overall health and identify any underlying conditions that could affect anesthesia safety.

  • X-rays are used to visualize the internal structures of a pet, primarily bones and some soft tissues.

    X-rays are useful for diagnosing fractures, arthritis, lung conditions, and some abdominal abnormalities like bladder stones or foreign bodies. They are quick and generally do not require sedation unless the pet is uncooperative.

  • Cytology involves examining cells under a microscope to identify abnormalities, infections, or cancerous changes.

    It is useful for diagnosing skin masses, lumps, and some internal conditions like infections or tumors. It helps determine if further testing or treatment is needed.

  • A biopsy involves removing a small sample of tissue for microscopic examination to diagnose diseases or conditions.

    Biopsies are crucial for diagnosing cancer, inflammatory conditions, and certain infections. They provide detailed information about the nature and severity of a disease, guiding treatment decisions.

These are just some examples of the many blood tests and screens available in veterinary medicine. The specific tests recommended for an animal will depend on factors such as its species, breed, age, medical history, and clinical signs. Veterinary professionals interpret the results of these tests along with other diagnostic information to provide comprehensive care for their patients.
