In-House Diagnostics

Early detection is key when it comes to treating your pet, and Mercer Street Veterinary Hospital offers complete in-house diagnostics including cutting-edge equipment and an on-site laboratory. This saves time, money, and most importantly, you don’t have to wait overnight for results—meaning your pet gets a diagnosis and needed treatment sooner.

In-House Laboratory

We have the capability to perform various blood screens, pre-anesthetic bloodwork, urinalysis, dermatological analysis, and other types of testing onsite when needed.


Ultrasound is a powerful diagnostic tool that creates a real-time image of an animal’s body. This composite reveals important information about internal processes including the circulatory and gastrointestinal systems.

When used in conjunction with other diagnostic tools, ultrasounds can help identify disease, blockages, soft tissue damage, and other internal injuries.

An ultrasound works by broadcasting high-frequency sound waves that reflect off your pet’s internal structures. A small probe held against the skin collects the returning signals to create an image of the internal body, most commonly used to examine abdominal organs like the stomach, kidneys, liver, spleen, and gallbladder.


We’re proud to partner with a mobile cardiologist to offer echocardiograms to patients we suspect might be suffering from disease or malfunction of the heart. An echocardiogram is an ultrasound of the heart muscle and tissue, providing precise information about valves, blood flow, chamber size, and contractions.
