What Can a Simple Blood Test Tell Us About Your Pet’s Health?
Family Pet Hospital
Your pet’s annual exam tells us a lot, but sometimes we need to look a little deeper.
That is where bloodwork comes in.
A blood test can give your veterinary team information about parts of your pet’s health that cannot be seen during a physical exam. It may help us establish a baseline while your pet is healthy, investigate symptoms, prepare for anesthesia, or monitor a medical condition.
At Family Pet Hospital in Mapleton, the question is not whether every pet should have the same bloodwork every year. It is what information is useful for your pet right now.
So, what can bloodwork actually tell us?
A Look at Blood Cells
One common test is a complete blood count, often called a CBC.
It looks at red blood cells, white blood cells, and platelets.
Changes in these cells can give us information about issues such as anemia, inflammation, infection, or problems with clotting. The results need to be interpreted along with your pet’s symptoms and physical exam.
A single number rarely tells the whole story.
A Look at Organs and Metabolism
A chemistry panel gives us a different set of information.
It includes measurements related to things such as the kidneys, liver, blood sugar, proteins, and electrolytes.
If your pet is sick, these results may help us understand what systems could be involved. If your pet is healthy, they can give us a baseline for future comparison.
Depending on your pet’s age or symptoms, we may recommend additional testing too.
What About Puppies and Kittens?
Most healthy puppies and kittens do not need comprehensive bloodwork at every routine visit.
Testing may be recommended if a young pet has symptoms such as poor appetite, repeated vomiting or diarrhea, weakness, low energy, or poor growth.
Bloodwork is also commonly recommended before anesthesia.
If your puppy or kitten is having a spay, neuter, or another procedure, testing gives us additional information before medications are given.
Even when a young pet looks completely healthy, there are internal values we cannot evaluate during the physical exam alone.
Healthy Adult Pets: Why Normal Results Matter
When your pet’s bloodwork is normal, it may feel like nothing happened.
Actually, something useful did happen.
We learned what your pet’s normal looks like.
When we repeat bloodwork later, we can compare new results with earlier ones. That helps us see whether values are staying steady or beginning to change.
For some healthy adult pets, annual bloodwork may make sense. Others may follow a different schedule depending on age, breed, lifestyle, medical history, and previous results.
Senior Pets: Bloodwork Can Help Us Catch Subtle Changes
Older pets often need closer monitoring because the risk of chronic disease increases with age.
The signs can be easy to miss.
Your dog may drink more water than usual. Your cat may lose weight but still eat well. Your pet may sleep more, become less active, or need more frequent bathroom breaks.
Bloodwork can help us look for possible medical reasons.
Kidney disease, diabetes, liver changes, thyroid conditions, and anemia are examples of problems that may affect senior pets.
Some senior dogs and cats may benefit from bloodwork every six to twelve months. Pets with existing conditions or medications may need testing more often.
There is no universal age when every pet becomes senior. Large dogs generally reach that stage earlier than smaller dogs.
When Symptoms Mean We Should Look Sooner
If your pet is not feeling well, we do not have to wait for their next wellness exam.
Persistent vomiting or diarrhea, unexplained weight loss, increased thirst, frequent urination, poor appetite, weakness, pale gums, collapse, significant lethargy, or another meaningful change can be reasons to recommend bloodwork.
The results may help us decide what comes next.
Sometimes that means treatment. Other times we may recommend urine testing, imaging, or another diagnostic test.
Medication Monitoring Is Another Common Reason
If your pet takes certain medications long term, bloodwork may be part of the treatment plan.
We may need to monitor kidney or liver values, blood cells, electrolytes, or whether the medication is having the intended effect.
Testing may be recommended after treatment begins, after a dose adjustment, and periodically once your pet is stable.
If you are ever unsure why your pet needs another blood test, ask. We are happy to explain what we are checking and why.
Before Anesthesia: Why Bloodwork Is Often Recommended
Before surgery or another procedure requiring anesthesia, bloodwork can give us additional information about your pet’s health.
A physical exam is essential, but it cannot measure every internal value.
If something unexpected appears, we may adjust the anesthetic plan, recommend another test, or postpone an elective procedure.
Normal results are helpful too. They give us information for the procedure and another healthy baseline for future comparison.
One Test, Lots of Useful Information
Bloodwork is not a perfect window into every part of your pet’s health, but it can tell us a lot.
At Family Pet Hospital, we recommend testing based on your pet’s age, medical history, medications, symptoms, lifestyle, and previous results.
If you are not sure when your pet last had bloodwork, ask us at the next visit. We can review their history and help you decide whether it is time to check again.
