Blood Tests for Cats

At PetWorks Veterinary Hospital, we offer in-house laboratory services. Our on-site equipment allows us to carry out some diagnostic tests, including complete blood chemistries, urinalysis, complete blood counts and fecal examinations. We also offer in-house testing for heartworm, tick-borne diseases, feline leukemia virus, feline immunodeficiency virus and parvovirus. Being able to perform these diagnostic tests in-house means that our veterinarians can promptly confirm a diagnosis and allows them to offer you immediate treatment recommendations. We also have access to outside laboratories for specialized diagnostics and consultations.

Why does my kitty need a blood screen?

The physical exam is only part of the picture, blood testing allows for much greater insight into what is going on with your pet’s health internally, and it can help us detect disease earlier when no symptoms are present. It is an essential part of veterinary (or human) diagnosis. Is critical to a rapid and accurate diagnosis.

How long does it take to get blood test results?

The most common place that we collect blood from your pet is from their jugular vein. The reason that we collect blood from the jugular vein is not that us vets are secreted vampires, in fact, because the blood flow is greater from the jugular vein. Which means your pet has to stay still for a shorter time and ideally, we want to preserve your pet’s other veins which may be needed for intravenous catheterization (e.g. placement of an IV drip).

What precautions should I take before a blood test?

Some blood tests are time sensitive or will require fasting, this isn’t as common for cats as it is for dogs. Your veterinarian will advise you on the appropriate steps required before your cat’s blood test.

How often should blood tests be done?

Healthy adult dogs and cats need an annual exam from their vet. At that time, a physical exam and pet history will be obtained. The physical exam findings will be review with you, and your vet will determine if your pet will need any blood work to monitor their well-being further. Regular and routine blood testing is an important part of your cat’s preventive health care.
