Diagnostic Tests & Laboratory Panels
Browse 27 diagnostic procedures and bloodwork markers. Learn how complete blood counts (CBC), chemistry panels, urinalysis, radiographs, ultrasound, and point-of-care SNAP tests establish your pet's diagnosis.
Abdominal Ultrasound
A real-time, non-invasive imaging modality using high-frequency sound waves to visualize internal soft tissue organ architecture and fluid.
ACTH Stimulation Test
An endocrine blood test that evaluates adrenal gland reserve capacity by measuring blood cortisol before and after injecting synthetic adrenocorticotropic hormone.
Alanine Aminotransferase (ALT)
A liver enzyme found inside liver cells that leaks into the bloodstream when hepatocytes are damaged or inflamed.
Alkaline Phosphatase (ALP)
An inducible enzyme found on the biliary membranes of the liver, bone cells, and (in dogs) induced by steroid hormones.
Blood Urea Nitrogen (BUN)
A metabolic waste product of dietary protein digestion and liver metabolism, excreted primarily by the kidneys.
Complete Blood Count (CBC)
A core laboratory panel that quantifies and evaluates the three primary cellular components of blood: red blood cells, white blood cells, and platelets.
Computed Tomography (CT Scan)
An advanced cross-sectional imaging technique that uses rotating X-rays and computer processing to create detailed three-dimensional volumetric images.
Creatinine
A waste byproduct of normal muscle breakdown excreted exclusively by the kidneys; the primary blood biomarker for renal filtration and IRIS staging.
Echocardiogram (Echo)
A non-invasive ultrasound examination of the heart that evaluates cardiac chamber dimensions, muscle thickness, valve function, and blood flow velocity.
Fecal Flotation with Centrifugation
A microscopic parasitological test utilizing high-density flotation solutions and centrifugal force to concentrate and identify intestinal parasite eggs and cysts.
FIV / FeLV SNAP Combo Test
An in-clinic ELISA blood test that simultaneously screens cats for Feline Immunodeficiency Virus antibodies and Feline Leukemia Virus antigens.
Fluorescein Eye Stain Test
An ophthalmic diagnostic test utilizing water-soluble orange-fluorescent dye to detect corneal epithelial defects, ulcers, and nasolacrimal drainage.
Heartworm Antigen Test
An in-clinic ELISA or lateral-flow immunoassay detecting uterine glycoprotein antigens secreted by mature adult female Dirofilaria immitis heartworms.
Hematocrit (HCT) / Packed Cell Volume (PCV)
The percentage of whole blood volume made up of red blood cells, providing the primary measure of anemia and hydration status.
Low-Dose Dexamethasone Suppression Test (LDDST)
An 8-hour dynamic endocrine test that screens for Cushingβs disease and differentiates pituitary-dependent from adrenal-dependent forms.
Magnetic Resonance Imaging (MRI)
A premier diagnostic imaging modality utilizing powerful magnetic fields and radio waves to generate exquisite soft-tissue contrast of the brain, spinal cord, and nerves.
Platelet Count (Thrombocytes)
A quantitative count of circulating thrombocyte cell fragments essential for primary blood clotting and plugging vascular leaks.
Radiograph (X-Ray)
A non-invasive diagnostic imaging modality using ionizing radiation to produce two-dimensional shadow projections of internal bones, lungs, and organs.
Serum Bile Acids (Pre- & Post-Prandial Tolerance Test)
A dynamic paired liver function test measuring serum bile acid concentrations before and 2 hours after a meal to evaluate hepatic vascular and parenchymal integrity.
Serum Chemistry Profile (Chem Panel)
A panel of blood biochemical tests that evaluates organ function, electrolytes, blood sugar, and metabolic status.
Serum Fructosamine Test
A quantitative serum blood test measuring glycated serum protein to evaluate average blood glucose concentrations over the preceding 2 to 3 weeks.
Spec cPL / SNAP cPL (Canine Pancreatic Lipase)
A highly sensitive and specific immunoassay measuring canine pancreatic-specific lipase to diagnose or rule out acute pancreatitis.
Symmetric Dimethylarginine (SDMA)
A sensitive renal biomarker produced by cellular metabolism and excreted by the kidneys, detecting kidney function loss earlier than traditional creatinine.
Tonometry (Intraocular Pressure Measurement)
An ophthalmic diagnostic procedure measuring intraocular pressure (IOP) in millimeters of mercury (mmHg) to screen for glaucoma and uveitis.
Total T4 (Serum Thyroxine Test)
A quantitative serum immunoassay measuring the total concentration of circulating thyroxine (protein-bound and free T4).
UPC (Urine Protein:Creatinine Ratio)
A quantitative laboratory test measuring the ratio of protein to creatinine in urine to diagnose and quantify renal glomerular protein loss.
Urinalysis (UA)
A physical, chemical, and microscopic examination of urine to evaluate kidney function and the lower urinary tract.
