What Can Bloodwork Tell Me About My Pet’s Health?

Pet blood tests provide valuable insight into your pet’s internal health, even before symptoms appear.

Diagnostic testing can help detect:

Infection or inflammation
Organ function issues (kidneys, liver)
Hormonal imbalances
Blood disorders
Early signs of chronic disease

Routine testing allows us to monitor trends over time and catch health concerns early when treatment is most effective.

What Is Veterinary Diagnostic Testing?

Veterinary diagnostic testing includes a range of tools used to evaluate your pet’s internal health. These tests allow us to assess organ function, detect infection, identify inflammation, and uncover hidden disease before symptoms become severe.

At our Manassas veterinary hospital, we offer comprehensive in-house diagnostic services for faster, more accurate results.

Thyroid Testing: Screens for hypothyroidism (dogs) and hyperthyroidism (cats)
Blood Gases Monitoring: Assesses oxygen, carbon dioxide, and pH balance

Before Surgery
