Pet Blood Work & Lab Testing in Philadelphia, PA
Blood work is one of the most valuable tools we have for understanding your pet’s health—giving us answers that a physical exam alone cannot provide.
Pet Blood Work
Your pet can’t tell you where it hurts. That’s why lab work and blood testing play such an essential role in veterinary medicine—helping our team get to the root of a problem quickly and accurately.
Blood tests allow us to collect and analyze a sample to learn what’s happening inside your pet’s body. The results give us immediate, detailed information that we may not be able to gather any other way. Whether you’ve noticed something off with your dog or cat, your pet is preparing for surgery, or it’s simply time for their annual wellness visit, blood work at Companion Pet Hospital helps us get you the answers you need.
Blood testing is highly effective for diagnosing a wide range of health concerns, including liver and kidney function, bleeding disorders, immune system disorders, oxygen-carrying capacity, congenital conditions, infection, anemia, and inflammation.
When Should My Pet Have Blood Work Done?
We recommend routine blood work for puppies and kittens, senior pets, pregnant animals, and pets with a history of health concerns. Testing during a routine wellness exam allows us to identify potential issues before outward symptoms appear—and early detection can lead to better outcomes and lower treatment costs over time.
Testing a healthy pet also helps us establish a baseline for their individual values. When something changes in future results, we have a reference point to work from—making it much easier to catch a developing problem early.
If your pet is scheduled for surgery, blood work is always performed beforehand to confirm their safety under anesthesia. Lab results help us assess kidney and liver function to determine the safest anesthesia level for your individual pet. If any concerns appear, we’ll work with you to reschedule or explore alternative treatment options before proceeding.
