The Drake Center features a complete in-house laboratory, which allows us to receive immediate results for pets with emergency or urgent care needs. We also work with an external laboratory that can provide results for many other tests, such as a fecal examination
screening, within 24 hours.
At The Drake Center, we recommend one "baseline" blood panel and urine screening on each pet before six months of age.
For pets under eight years of age, lab work should be repeated every one to two years as needed. We recommend annual labs for all senior pets.
In addition, fecal exams for the screening of intestinal parasites and blood test for heartworm infection in dogs are recommended annually.
Understanding your pet's lab work
Blood and urine tests help doctors determine causes of illness and monitor the progress of medical treatments. This guide is designed to help you better understand your pet’s results as well as our recommendations for treatment.
Complete Blood Count
This is the most common blood test performed on pets and people. A Complete Blood Count, or CBC, provides information on hydration status, anemia, infection, blood clotting ability and immune system response. This test is essential for pets with symptoms such as fever, vomiting
, weakness, pale gums or loss of appetite. If your pet needs surgery, a CBC can detect bleeding disorders or other unseen abnormalities.
- Hematocrit (HCT): This test measures the percentage of red blood cells to detect anemia and hydration.
- Hemoglobin and mean corpulscular hemoglobin concentration (Hb and MCHC): These are the oxygen-carrying pigments of red blood cells.
- White blood cell count (WBC): This test measures the body’s immune cells. Increases or decreases in the WBC indicate certain diseases or infections.
- Granulocytes and lymphocytes/monocytes (GRANS and L/M): These are specific types of white blood cells.
- Eosinophils (EOS): These are a specific type of white blood cells that may indicate allergic or parasitic conditions.
- Platelet count (PLT): This test measures cells that form blood clots.
- Reticulocytes (RETICS): These are are immature red blood cells. High levels may indicate regenerative anemia.
- Fibrinogen (FIBR): This test provides important information about blood clotting. High levels may indicate a dog is 30 to 40 days pregnant.
These common blood serum tests evaluate organ function, electrolyte status and hormone levels. In addition to assessing organ health in pets receiving long-term medications or undergoing anesthesia, these tests are especially important in evaluating senior pets and those with signs of vomiting, diarrhea or toxin exposure.
- Albumin (ALB): This is a serum protein that helps evaluate hydration, hemorrhage and intestinal, liver and kidney disease.
- Alkaline phosphatase (ALKP): Elevations in this test may indicate liver damage, Cushing’s disease or active bone growth in a young pet. This test is especially significant in cats.
- Alanine aminotansferase (ALT): This test may determine active liver damage, but does not indicate the cause.
- Amylase (AMYL): Elevations in this test may indicate pancreatitis or kidney disease.
- Aspartate aminotransferase (AST): Increases in this test may indicate liver, heart or skeletal muscle damage.
- Blood urea nitrogen (BUN): This test determines kidney function. An increased level is called azotemia and can be caused by kidney, liver and heart disease as well as urethral obstruction, shock or dehydration.
- Calcium (Ca): Changes in the normal level of this test can indicate a variety of conditions, including tumors, hyperparathyroidism, kidney disease, and low albumin levels.
- Cholesterol (CHOL): This test is used to supplement diagnosis of hypothyroidism, liver disease, Cushing’s disease and diabetes.
- Chloride (Cl): Chloride is an electrolyte that is typically lost with symptoms like vomiting or illnesses such as Addison’s disease. Elevations often indicate dehydration.
- Coristol (CORT): Cortisol is a hormone that is measured in tests for both Cushing’s disease (low-dose dexamethasone suppression test) and Addison’s disease (ACTH stimulation test).
- Creatinine (CREA): This test reveals kidney function and can help determine the cause of elevated BUN.
- Gamma Glutamy transferase (GGT): This is an enzyme that indicates liver disease or corticosteroid excess.
- Globulin (GLOB): This is a blood protein that often increases with chronic inflammation and certain disease states.
- Glucose (GLU): Glucose is a blood sugar. Elevated levels may indicate diabetes, while low levels can cause collapse, seizures or coma.
- Potassium (K): This is an electrolyte typically lost with symptoms such as vomiting, diarrhea or excessive urination. Increased levels may indicate kidney failure, Addison’s disease, dehydration or urethral obstruction. High levels can lead to cardiac arrest.
- Lipase (LIP): Lipase is an enzyme that may indicate pancreatitis.
- Sodium (Na): Sodium is an electrolyte often lost with vomiting, diarrhea, kidney disease and Addison’s disease. This test helps indicate hydration status.
- Phosphorus (PHOS): Elevations in this test are often associated with kidney disease, hyperthyroidism and bleeding disorders.
- Total bilirubin (TBIL): Elevations in this test may indicate liver or hemolytic disease. This test helps identify bile duct problems and certain types of anemia.
- Total protein: This test indicates hydration status and provides additional information about the liver, kidneys and infectious diseases.
- Thyroxine (T4): Thyroxine is a thyroid hormone. Decreased levels often signal hypothyroidism in dogs, while high levels indicate hyperthyroidism in cats.
