Our Clinical Practice
Our lab conducts clinical procedures and any procedure will be discussed to make a tailored diagnostic plan for each individual animal.

The benefits, risks, and costs of all procedures will be discussed to make a tailored diagnostic plan for each individual animal. Components of complete diagnostic evaluation for liver disease in horses include:
- Complete history and physical examination
- Specialized bloodwork for liver injury and function
- Blood tests for hepatitis viruses
- Abdominal ultrasound with special focus on the liver
- Liver biopsy for culture, viral testing, and histopathology
- +/- Endoscopy of the stomach and duodenum
Liver biopsies are routinely performed in horses with a low rate of complications. The procedure is performed in a standing sedated horse with local analgesia and a small needle through the skin. Although complications are rare, we recommend an overnight stay after biopsy for monitoring.
