Types Of Blood Tests for Cats

Blood tests  are important diagnostic tools that veterinarians use to evaluate and maintain feline health. The basic types of blood tests are the Complete Blood Count (CBC) and the Biochemistry Panel. The complete blood count (CBC) quantifies many blood constituents, such as red blood cells (RBCs), white blood cells (WBCs), and platelets.

1- Complete blood count (CBC):

Red Blood Cells (RBC): Assesses anemia or polycythemia.
White blood cells (WBC): indicate infection, inflammation, or leukemia.
Platelets: Determines clotting ability.

2- Biochemistry Panel:

Renal Function (BUN and Creatinine): Detects renal disease.
Liver Enzymes (ALT, AST, and ALP): Determines liver health.

3- Blood glucose tests for diabetes

Electrolytes (sodium, potassium, chloride): Assesses hydration and balance.
Proteins (Albumin, Globulin): Checks nutritional status and immunological function.

4- Thyroid Function Tests

Total T4 (Thyroxine) detects hyperthyroidism

5- FeLV/FIV Test

Feline Leukemia Virus (FeLV) and Feline Immunodeficiency Virus (FIV): Viral infection screening tests.

6- Electrolyte Panel:

Sodium, potassium, and chloride: Assesses hydration, acid-base balance, and kidney function.

7- Urinalysis:

Often used with blood testing to provide a thorough picture of kidney and urinary tract health.

Blood test Costs for cats

Blood test costs for cats may vary significantly based on a number of variables, such as the test type, the region, and the veterinary facility. The following are typical pricing ranges for typical cat blood tests:

  • Total Blood Count (CBC): usually falls between $50 and $100. This test counts the red blood cells, white blood cells, and platelets among other blood constituents.
  • Costs for Biochemical Profile: Typically range from $80 to $150. This test measures electrolyte levels and assesses the performance of organs such the pancreas, liver, and kidneys.
  • The cost of a thyroid function test typically ranges from $50 to $150. In order to identify hyperthyroidism or hypothyroidism, this test analyzes thyroid hormone levels.
  • Tests for the feline immunodeficiency virus (FIV) and leukemia virus (FeLV) typically cost between $30 and $60. These examinations look for viral infections that can weaken a cat’s defenses against disease.
  • Senior Cat Blood Panel: Usually ranges in price from $100 to $200. A CBC, a metabolic profile, and other tests specifically designed for senior cats are included in this comprehensive panel.
  • Blood work before to anesthesia: Typically costs $40 to $100. In order to make sure the cat is healthy enough for surgery, this is done prior to anesthesia.

Chem 17 blood test for cats

Comprehensive chemistry panels, or Chem 17 blood tests, are often employed as diagnostic tools in veterinary medicine. Usually, it consists of 17 distinct tests that assess different facets of a cat’s health, with an emphasis on organ function and metabolic state. The following elements are often seen in a Chem 17 panel:

  • Albumin (ALB)
  • ALKP, or alkaline phosphatase
  • Aminotransferase Alanine (ALT)
  • Amylase (AMYL)
  • Total Bilirubin (TBIL)
  • Blood Nitrogen Urea (BUN)
  • Calcium (CA)
  • The substance cholesterol (CHOL)
  • The chemical creatinine (CREA)
  • GLU, or glucose
  • Phosporus (PHOS)
  • Potassium (K)
  • Protein Total (TP)
  • Sodium (NA)
  • Chloride (CL)
  • Globulin (GLOB)
  • The element magnesium (MG)

Blood Tests For Cats With Kidney Disease

  • Elevations in blood urea nitrogen (BUN) indicate renal failure.
  • A marker of renal function, elevated levels of creatinine indicate reduced function.
  • Symmetric Dimethylarginine, or SDMA, is a precursor to renal disease.
  • Electrolytes: Keeps track of sodium, potassium, phosphorus, and calcium levels; imbalances are common in illnesses affecting the kidneys.
  • Phosphorus: Increased levels may make renal illness worse.
  • Calcium: Examines for anomalies related to kidney illness.
  • Anemia, infection, and inflammation can all be found using a complete blood count (CBC).
  • Urinalysis: assesses kidney dysfunction and finds proteinuria.
  • Assess blood protein levels using total protein and albumin; low readings may indicate protein loss.
  • Measurement of Blood Pressure: When a patient has renal sickness, high blood pressure is common and harmful.

Preparing for a Blood Test

  • Fasting: May be required for 6-12 hours before the test.
  • Stress Reduction: Keeping the cat calm can help ensure a smooth blood draw.

To achieve appropriate results for a blood test, your cat may need to fast for 6-12 hours prior. Keeping your cat relaxed and stress-free is also vital for a successful blood draw. The blood sample will be collected by the veterinarian or veterinary technician, usually from a vein in the cat’s leg or neck, in a quick and relatively painless procedure.

Once the blood tests are completed, your veterinarian will go over the results with you, discussing any abnormalities and their implications for your cat’s health. These findings may lead to recommendations for additional testing or therapies. Regular blood tests are essential for keeping your cat healthy, as they enable for early detection of potential health problems and effective monitoring of chronic diseases.

Frequent blood testing establishes a baseline for your cat’s health, which makes it easier to identify deviations from the norm in later testing. This will be especially helpful when your cat gets older.

7- Identifying infections and inflammations:

Blood tests can detect immune system abnormalities, infections, and inflammations. They can also reveal the underlying reasons of symptoms including weariness, fever, and appetite loss.

8- Recognizing poisons and toxins:

Blood tests can be used to identify the substances and determine the appropriate course of therapy if a cat is suspected of eating poisons or toxins.

9- Conditions unique to a breed and genetics:

Certain blood tests can identify diseases or genetic problems specific to a breed, which enables early detection and treatment of potential health issues.

10- Checkup for General Health:

Frequent blood tests are an important part of normal veterinary visits, allowing for a full assessment of your cat’s overall health.

11- Hormonal Disproportions:

Hormonal imbalances, such as hypo- or hyperthyroidism, are common in cats and can have a significant detrimental impact on their quality of life if left untreated. Blood testing can help detect these abnormalities.
