Think of it as a health check-up, giving you peace of mind and ensuring your cat lives a long and happy life. Let’s explore which blood tests are important and how they help!
Why Blood Tests Matter for Your British Shorthair

Blood tests are a key part of preventive care for your British Shorthair. They provide a snapshot of your cat’s overall health, helping your vet identify potential problems before they become serious. Early detection allows for timely treatment and can significantly improve your cat’s quality of life.
Common Health Concerns in British Shorthairs
British Shorthairs are predisposed to certain health conditions. Knowing about these risks can help you be proactive about your cat’s health:
- Hypertrophic Cardiomyopathy (HCM): A heart condition where the heart muscle thickens, making it harder for the heart to pump blood effectively.
- Polycystic Kidney Disease (PKD): A genetic disorder that causes cysts to form on the kidneys, eventually leading to kidney failure.
- Diabetes Mellitus: A metabolic disorder where the body doesn’t produce enough insulin or can’t use it effectively, leading to high blood sugar levels.
- Hyperthyroidism: A condition where the thyroid gland produces too much thyroid hormone, leading to a faster metabolism.
How Blood Tests Help
Blood tests can help detect these conditions early:
- Identify early signs of disease: Blood tests can reveal abnormalities that might not be apparent during a physical exam.
- Monitor existing conditions: If your cat has a known health issue, blood tests can help track its progress and adjust treatment as needed.
- Assess organ function: Blood tests can provide valuable information about the health of your cat’s kidneys, liver, and other vital organs.
Essential Blood Tests for Adult British Shorthairs

Here are some of the most important blood tests for adult British Shorthairs:
1. Complete Blood Count (CBC)
A CBC provides information about the different types of cells in your cat’s blood, including red blood cells, white blood cells, and platelets.
What it measures:
- Red blood cells: Detects anemia (low red blood cell count) or polycythemia (high red blood cell count).
- White blood cells: Detects infections, inflammation, and immune system disorders.
- Platelets: Assesses the blood’s ability to clot.
Why it’s important:
A CBC can help diagnose a wide range of conditions, from infections and anemia to more serious diseases like leukemia.
2. Blood Chemistry Panel
A blood chemistry panel measures various substances in your cat’s blood, providing information about organ function and overall health.
Key components:
- Kidney values (BUN and creatinine): Assesses kidney function. Elevated levels can indicate kidney disease, a common problem in older cats.
- Liver enzymes (ALT, AST, ALP): Assesses liver function. Elevated levels can indicate liver damage or disease.
- Blood glucose: Measures blood sugar levels. High levels can indicate diabetes.
- Electrolytes (sodium, potassium, chloride): Assesses electrolyte balance. Imbalances can indicate dehydration, kidney disease, or other problems.
- Total protein and albumin: Measures protein levels in the blood. Abnormal levels can indicate liver disease, kidney disease, or malnutrition.
Why it’s important:
A blood chemistry panel can help detect kidney disease, liver disease, diabetes, and other metabolic disorders. According to the Cornell Feline Health Center, kidney disease is a leading cause of illness and death in older cats, making kidney values a critical part of the blood chemistry panel.
3. Thyroid Testing (T4)
A T4 test measures the level of thyroid hormone in your cat’s blood. It’s primarily used to detect hyperthyroidism, a common condition in older cats.
Why it’s important:
Hyperthyroidism can cause a variety of symptoms, including weight loss, increased appetite, hyperactivity, and vomiting. Early detection and treatment can significantly improve your cat’s quality of life.
4. ProBNP Test
The ProBNP test is a blood test that helps screen for heart disease, particularly hypertrophic cardiomyopathy (HCM), in cats. It measures the level of a specific protein released by the heart when it is under stress. While not a definitive diagnosis, an elevated ProBNP level can indicate the need for further cardiac evaluation, such as an echocardiogram.
Why it’s important:
HCM is a common heart condition in British Shorthairs. Early detection, while not curative, allows for earlier management and potentially slowing the progression of the disease. The earlier you catch it, the sooner you can work with your vet on the best course of action.
5. Fructosamine Test
The fructosamine test is a blood test used to assess a cat’s average blood glucose levels over the past 2-3 weeks. This test is particularly helpful in diagnosing and monitoring diabetes mellitus in cats.
Why it’s important:
Unlike a single blood glucose measurement, which can be affected by stress, the fructosamine test provides a more stable and reliable indicator of long-term glucose control. This is especially important for cats who get stressed at the vet, as the stress can temporarily raise blood sugar levels. This test helps differentiate between stress-induced hyperglycemia and true diabetes.
Understanding the Results

It’s important to remember that blood test results are just one piece of the puzzle. Your vet will consider the results in conjunction with your cat’s physical exam, medical history, and any symptoms they may be experiencing.
Normal Ranges
Each laboratory has its own reference ranges for blood test values. These ranges are based on the average values found in a healthy population of cats. Your vet will interpret your cat’s results in light of these reference ranges.
What Abnormal Results Mean
Abnormal blood test results don’t always mean that your cat is sick. Sometimes, they can be caused by factors such as stress, dehydration, or medication. However, abnormal results can also indicate an underlying health problem.
Here’s a simple table outlining what some abnormal results *might* indicate. *Always* consult your vet for an accurate diagnosis!
| Test | High Result (Potential Indication) | Low Result (Potential Indication) |
|---|---|---|
| BUN (Kidney) | Kidney disease, dehydration | Rarely significant |
| ALT (Liver) | Liver damage, inflammation | Rarely significant |
| Glucose | Diabetes, stress | Hypoglycemia (rare) |
| T4 (Thyroid) | Hyperthyroidism | Hypothyroidism (rare in cats) |
Next Steps After Abnormal Results
If your cat’s blood test results are abnormal, your vet may recommend further testing to determine the cause. This could include additional blood tests, urine tests, imaging tests (such as X-rays or ultrasound), or other diagnostic procedures. The RSPCA recommends following your vet’s guidance closely for the best outcome.
Frequency of Blood Tests

How often your British Shorthair needs blood tests depends on several factors, including their age, health history, and lifestyle.
General Guidelines
- Annual blood tests: Generally recommended for adult cats (1-7 years old) as part of their routine checkup.
- More frequent testing: May be recommended for senior cats (8+ years old) or cats with known health problems. Your vet might suggest blood tests every 6 months to monitor their condition more closely.
Factors Affecting Frequency
Your vet may recommend more frequent blood tests if your cat has:
- A history of health problems
- Is taking medication that can affect organ function
- Is showing signs of illness
Preparing Your Cat for a Blood Test
Getting your cat ready for a blood test can help make the process smoother and less stressful for both of you.
Before the Appointment
- Fasting: Your vet may ask you to withhold food for a certain period (usually 8-12 hours) before the blood test. This is because food can affect certain blood test results, such as blood glucose levels. Always follow your vet’s instructions regarding fasting. Water is usually allowed.
- Medications: Inform your vet about any medications your cat is taking, as some medications can affect blood test results.
- Reduce stress: Help your cat stay calm by using a calming pheromone spray in the carrier.
